Add Maven support to an existing project

You can open an existing non-Maven project (plain Java project) and add a Maven support via IntelliJ IDEA UI.

Before you start adding Maven to your project, please read Maven documentation to familiarize yourself with Maven concepts and components.

Add Maven support

  1. Open an existing project, for example, a Java project.
  2. In the Project tool window Alt+1 , select the module or the project directory to which you want to add Maven.
  3. Press Ctrl+Shift+A and type Add Framework Support . Once the action is found, click it to open the Add Framework Support dialog.
  4. In the dialog that opens, select Maven from the options on the left and click OK . Add Maven supportIntelliJ IDEA adds a default POM to the project and generates the standard Maven layout in Project tool window. Maven project viewIntelliJ IDEA also creates a corresponding structure with Lifecycle and Plugins in the Maven tool window. Maven tool window
  5. Open the generated POM and specify a groupId . The artifactId and version are specified automatically. For more information about Maven naming conventions, refer to the Maven documentation. Generated POMEvery time you change the POM, IntelliJ IDEA displays a popup suggesting to import your changes.

At this point you can further develop your project using Maven. We recommend making all your project changes in POM since IntelliJ IDEA considers pom.xml as a single source of truth.

Create an executable JAR

You can conclude the following optional steps to create an executable JAR.

the Manifest file

  1. From the main menu, select Build | Build Project () to build project. IntelliJ IDEA generates target folder. Note that IntelliJ IDEA only compiles sources and doesn’t create either JAR file or Manifest file.
  2. Create a Manifest file in the resources directory. Right-click the directory, select New | Directory to create the META-INF subdirectory. Then right-click the subdirectory, select New | File to create the MANIFEST.MF file.
  3. Open the MANIFEST.MF file in the editor and add information about your main class. Check the following code:

Main-Class: Main

Alternatively, we can ask Maven to add this line of code into the MANIFEST.MF file with the following code in pom.xml :

org.apache.maven.plugins maven-jar-plugin Main
  • In your POM specify the Manifest file information, so you can use Maven to generate an executable jar file. POM with manifestAlternatively, you can execute package instead of the install command to achieve the same result.
  • In the Maven tool window, in the Lifecycle list, double-click the install command to generate the jar file. IntelliJ IDEA generates the appropriate information in the target folder and an executable JAR in the Project tool window. Generated JARYou can right-click the generated JAR and select Run to execute the file.
  • If the existing project contains more than one module, converting such a project into the Maven project becomes quite challenging. In this case we recommend that you create an external POM where you describe your project and open your POM as you would open a regular Maven project.

    Поздний ответ, наверное, но для истории:

    Можно в корень обычного проекта в IDEA добавить pom.xml (хоть из другого проекта), подправить ему group, artifact, зависимости. Потом в контекстном меню для этого файла выбрать «Add as Maven Project». Проект станет теперь maven, дальше уже настраиваем его как обычный maven-проект.

    Update простейший XML файл имеет вид

    Maven

    IntelliJ IDEA supports a fully-functional integration with Maven that helps you automate your building process. You can easily create a new Maven project, open and sync an existing one, add a Maven support to any existing IntelliJ IDEA project, configure and manage a multi-module project.

    You can also create a Maven project and store it in the WSL environment or open it from the WSL file system. For more information, refer to the WSL section.

    If you want to use a custom Maven version that is not bundled with IntelliJ IDEA, you need to install it locally.

    Create a new Maven project

    New project Maven

    1. If no project is currently open in IntelliJ IDEA, click New Project on the Welcome screen. Otherwise, select File | New | Project from the main menu.
    2. Name the new project and change its location if necessary.
    3. Select the Create Git repository to place the new project under version control. You will be able to do it later at any time.
    4. Select a language that you want to use in your project. Click if you want to add other languages available via plugins.
    5. Select Maven in the list of Build system .
    6. Specify project’s SDK (JDK) or use the default one.
    7. The selected Add sample code option will create a file with a basic code sample.
    8. In Advanced Settings , specify the following Maven coordinates that are added to the pom.xml file:
      • GroupId — a package of a new project.
      • ArtifactId — a name of your project.

    For more information about Maven coordinates, refer to Maven naming conventions.

    Create a new project with Maven archetype

    Maven archetype

    1. Launch the New Project wizard. If no project is currently opened in IntelliJ IDEA, click New Project on the welcome screen. Otherwise, select File | New | Project from the main menu.
    2. Select Maven Archetype from the options on the left.
    3. Using options on the right, configure your project:
      • Name : specify the name of your project.
      • Location : specify the location of your project.
      • Create Git repository : Select the Create Git repository to place the new project under version control. You will be able to do it later at any time. The .gitignore file is generated in any case.
      • JDK : specify project’s SDK (JDK) or use the default one.
      • Catalog : specify which Maven repository you want to use in your project. The internal Maven catalog is a default one. You can also select the local repository that is located in the .m2 directory, or you can select Maven central repository. You can also click Manage Catalogs and add a custom repository if you need.
      • Archetype : select the needed Maven archetype. Click Add to specify the custom archetype.
      • Version : the version is specified automatically.
      • Additional properties : add additional properties

    If you are creating a project using a Maven archetype, IntelliJ IDEA displays the Maven settings that you can use to set the Maven home path and Maven repositories. Also, you can check the archetype properties.

    To modify or add archetype catalogs later in your project, refer to the Archetype Catalogs settings.

    Create a Java EE project with Maven as a build tool

    1. Launch the New Project wizard. If no project is currently opened in IntelliJ IDEA, click New Project on the welcome screen. Otherwise, select File | New | Project from the main menu.
    2. Select Jakarta EE from the list of generators.
    3. Leave the default option Maven as your build tool system.
    4. Select additional libraries and frameworks.
    5. Specify your project’s name, location, and artifact coordinates. Click Create . IntelliJ IDEA creates a Maven project with the dedicated Maven tool window and adds necessary dependencies. For the more detailed information, refer to Tutorial: Your first Java EE application.

    Open an existing Maven project

    1. Go to File | Open . Alternatively, click Open on the welcome screen. If you have some custom plugins that require you to import your project from the IntelliJ IDEA model, press Ctrl+Shift+A and search for the Project from Existing Sources action.
    2. In the dialog that opens, select the pom.xml file of the project you want to open. Click OK .
    3. In the dialog that opens, click Open as Project .

    IntelliJ IDEA opens and syncs the Maven project in the IDE. If you need to adjust importing options when you open the project, refer to the Maven settings. For example, if you have Maven options configured in the maven/config file and want to use them in your project, select the Use settings from .mvn/maven.config option in the Maven setting.

    If you have a Maven project with the configured Maven wrapper then IntelliJ IDEA will take the Maven version from the maven.properties file and add it as the Maven home path.

    Configure the Maven settings before opening a new project

    You can configure IntelliJ IDEA to display Maven settings before you open a new Maven project. (A new Maven project in this case is the existing project that you open in IntelliJ IDEA for the first time.) Since these are application-level settings, they are applied to any new project you open.

    Maven Settings

    1. On the Welcome screen, select Customize | All Settings . Alternatively, go to File |New Project Setup | Preferences for New Projects in the main menu.
    2. In the Settings dialog, select Build, Execution, Deployment | Build Tools | Maven .
    3. In the Maven settings dialog, select the Show settings dialog for new Maven projects .
    4. Click OK to save the changes. Next time you open a new project, IntelliJ IDEA displays the Maven Settings dialog where you can specify a location of the local Maven repository and a user settings file.

    Add a new Maven module to an existing project

    You can add a Maven module to the project in which you are already working.

    1. In the Project tool window, right-click the project folder and select New | Module . Alternatively, go to File| New | Module in the main menu to open the New Module wizard.
    2. If you used the main menu to add a module, then the process of adding a module is the same as Creating a new Maven project. If you are adding submodules by right-clicking the root folder then the process of adding a new module is shorter. You need to specify the name of your module in the Name field. The rest of the information is added automatically, and you can use either the default settings or change them according to your preferences.

    Configure a multi-module Maven project

    You can create a multi-module Maven project in IntelliJ IDEA. The multi-module project is defined by a parent POM file with several submodules.

    If you have the Maven version 3.7 or later installed, IntelliJ IDEA will support importing a project from the MNG-6656 model.

    In this case when you open a child POM file in the editor, you don’t have to specify a version inside the parent tags if it is located in the relativePath by default. If you add a dependency to a module in the same project, you don’t have to specify a version of the dependent module.

    1. Create a Maven parent project. IntelliJ IDEA creates a standard Maven layout including an src folder.
    2. In the Project tool window, remove the src folder since you would only need it in the very rare cases. For your general project, you don’t need the src folder for the parent POM.
    3. In the Project tool window, right-click your project (or in the main menu, go to File ) and select New | Module to add a subproject.
    4. In the New Module wizard following the instructions on how to add a module, specify the necessary information and click Finish . The src folder is created automatically, and you can open POM and add a packaging that you need. IntelliJ IDEA adds the module to the parent project. IntelliJ IDEA also adds name and the description of the subproject to the parent POM. the parent POMIn a multi-module project, the parent POM needs to have a pom packaging. Last, but not least, IntelliJ IDEA adds the description of the parent POM to the subproject’s POM. the subproject POMYou can click in the left gutter to quickly open the parent POM from your subproject.
    5. You can also add dependencies to the parent POM that will be inherited by the subprojects. Parent POM: added dependency
    6. Open Maven tool window to see that all changes made in the parent POM are reflected in subprojects. the Maven tool window

    Access the Maven settings

    Use the Maven settings to configure options such as Maven version, local repository, offline mode, and so on.

    1. In the Settings dialog ( Ctrl+Alt+S ) , go to Build, Execution, Deployment| Maven . Click on the toolbar, in the Maven tool window to access the Maven settings.
    2. On the Maven settings page, configure the available options and click OK to save the changes.

    Use the Maven wrapper or a custom version of Maven

    The Maven2 version is not bundled with IntelliJ IDEA. If you need to use it in your project, download and enable the Maven2 support plugin.

    For a custom version, Download the needed Maven version on your computer.

    the Maven settings: Maven home path

    1. Press Ctrl+Alt+S to open the IDE settings and then select Build, Execution, Deployment | Build Tools | Maven .
    2. On the Maven settings page, in the Maven home path field, specify the location of the Maven custom version installation. For the Maven wrapper, select the use Maven wrapper option from the list. In this case the version of Maven defined in the .mvn/wrapper/maven-wrapper.properties file will be used.
    3. Click OK .

    Change the JDK version in a Maven project

    There are several places where you can change the JDK version that will affect not only your current project, but the whole application as well.

    Change the JDK version in the Project Structure

    Changing the JDK version in the Project Structure dialog will only affect the current project.

    Project Structure dialog / Project page

    1. In the main menu, go to File | Project Structure Ctrl+Alt+Shift+S .
    2. In the dialog that opens, in Project SDK , specify the JDK version and click OK to save the changes.

    Change the JDK version for the Maven runner

    When IntelliJ IDEA runs Maven goals, it will use the JDK version specified for the Maven runner. By default, IntelliJ IDEA uses the project’s JDK.

    Changing the JDK for the Maven runner will only affect the current project.

    Maven Settings / Runner page

    1. In the Settings dialog ( Ctrl+Alt+S ) , go to Build, Execution, Deployment | Maven | Runner .
    2. On the page that opens, in the JRE field, select the JDK version.

    Change the JDK version for the Maven importer

    Changing the JDK version for the Maven importer will affect the whole application since it is a part of the Maven global settings. If you want to use the same JDK version as you use in your project for syncing or resolving dependencies, change the JDK version for the importer.

    Maven Settings / Importing page

    1. In the Settings dialog ( Ctrl+Alt+S ) , go to Build, Execution, Deployment | Maven | Importing .
    2. On the page that opens, in the JDK for importer field, select the same JDK version as you used in the Project Structure and click OK to save the changes.

    Как из обычного IDEA-проекта сделать Maven

    Maven — это инструмент для сборки Java-проектов: компиляции, создания JAR, дистрибутива программы, генерации документации. С простыми проектами можно обойтись и без него — и собирать их в командной строке. Часто так и делают, но если проект большой и сложный, команда сборки выходит очень длинной, поэтому её иногда записывают в bat/sh-скрипт.

    Скрипты обычно зависят от платформы. Чтобы избавиться от этой зависимости и упростить работу, используют инструменты для сборки проекта, например Maven.

    Миграция на Maven

    Из любого стандартного проекта IDEA можно мигрировать на Maven-проект.

    В статье используется среда разработки JetBrains IDEA Community 2021.1. Если у вас другая версия, интерфейс может отличаться.

    Для этого выполните следующие действия:

    • Выберите проект или модуль, который будете добавлять в Maven, — в нашем примере это будет модуль LambdaExpressions.
