Maven dependencies

1. Open your POM in the editor.

2. Press Alt+Insert to open the Generate context menu.

3. From the context menu, select Dependency.

4. In the Maven Artifact Search tool window, in the search field, start typing the name of your dependency. In the list of results select the one you need and click Add.

   

   Aqua adds the dependency to your pom.xml.

   

   Aqua also adds the dependency to the Dependencies node in the Maven tool window and to the External Libraries in the Project tool window.

   If the added dependency has its own transitive dependencies, Aqua displays them in both tool windows.

   

Enable annotation processors

1. Open your POM file.

2. Specify the annotationProcessors and annotationProcessorPaths options.

   For example, check the following code:

   <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.5.1</version> <configuration> <annotationProcessorPaths> <path> <groupId>org.sample</groupId> <artifactId>sample-annotation-processor</artifactId> <version>1.2.3</version> </path> </annotationProcessorPaths> </configuration> </plugin> </plugins> </build>

   For more information, refer to Maven.

3. Re-import your project. Aqua creates an annotation processors profile, enables the annotation processing and adds the appropriate path to the Annotation Processor settings located in Settings | Build, Execution, Deployment | Compiler.

   

1. Open your POM in the editor.

2. Press Alt+Insert to open the Generate context menu.

3. From the context menu, select the Managed Dependency option that will show you the list of the dependencies that are defined in the dependencyManagement section of your parent POM in a multi-module project. Aqua also shows the list of dependencies from the BOM files.

   

4. Select the required dependency and click OK. The dependency is added to the POM. You don't need to specify the version on the dependency it will be taken from the DependencyManagement.

   

   However, if you want to overwrite the defined version, you need to include version when you add the managed dependency to the POM.

1. In your POM, in the dependency description add scope and using the code completion, add the name of the scope.

   <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.13.2</version> <scope>test</scope> </dependency>

2. Import your changes. The name of the scope is displayed in the Maven tool window. In the Project Structure dialog, on the Modules page you can see that the scope of the dependency is also displayed.

   

   Note that changing dependency's scope in the Project Structure dialog will not affect the pom.xml file.

You can also add a custom jar file as a dependency using the Maven scope system when you define your dependency. However, note that this dependency will only be available on your machine, and you can use it only for the local deployment.

View the transitive dependency

1. In your project's POM, press Ctrl and hover over the dependency.

2. Click the dependency to open the dependency's POM.

   

3. In the dependency POM, view the active dependency, its transitive dependencies and their versions.

   

   You can check the origin from which the dependency was pulled in.

   

Exclude the transitive dependency

You can exclude a transitive dependency if you want.

1. Open the dependency POM and find the transitive dependency you want to exclude. Copy groupId and artifactId.

2. In your project POM, underneath your active dependency, enter exclusions and using code completion paste the copied info of the dependency you want to exclude.

   <dependencyManagement> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.13.2</version> <scope>test</scope> <exclusions> <exclusion> <groupId>org.hamcrest</groupId> <artifactId>hamcrest-core</artifactId> </exclusion> </exclusions> </dependency> </dependencies> </dependencyManagement>

   The dependency is also excluded from the Project and Maven tool windows.

• In the pom.xml file, add a dependency you need. When you change the pom.xml, Aqua displays a notification suggesting to load the changes. Click in the editor to import the dependency and update your project.

• In the Maven tool window, press . In this case, you manually trigger the re-importing process of all projects and their dependencies.

Generate a diagram

1. In the Maven tool window, on the toolbar, click or select the appropriate option from the context menu.

   

2. In the diagram window, Aqua displays the sub-project and all its dependencies, including the transitive ones.

   

Change the visibility level

You can change the visibility level and, for example, view dependencies that have a specific scope (compile, test, and so on).

1. In the diagram window, select the subproject and click .

2. From the list, select the dependency scope you want to see. Aqua displays only the specified dependency scope.

   

Navigate to POM

You can navigate to POM from the diagram window.

• Select the required node, and press F4, or choose Jump to Source on its context menu. The corresponding file opens in the editor.

Check conflicts and duplicates

• In the diagram window, click icon.

The red arrow points to dependencies that contain duplicates or errors. Aqua also displays dependencies' versions to help you resolve the conflicts. Double-click the dependency to open its POM.

Show path from the selection to the root

You can select dependencies and see how they are included in the project.

1. In the diagram window, select a dependency for which you want to see a connection to a project. If you want to select several dependencies at once, hold down Shift and make the selection.

2. Click .

Show neighbors of the selected node

You can select dependencies and see what other dependencies are connected to the selected nodes. It might be helpful if you have a large diagram and want to focus on just a part of it.

1. In the diagram window, select a dependency you need. If you want to select several dependencies at once, hold down Shift and make the selection.

2. Click .

   

Analyze dependencies

1. On the toolbar in the Maven tool window, click .

   Alternatively, in the Maven tool window, right-click the needed dependency and select Analyze Dependencies from the context menu. You can also right-click a module in the Project view and use the same action.

   

2. In the Dependency Analyzer window, you can narrow down your analysis scope, check only the conflicted dependencies, or check usages.

   If you want to see the required dependency in the pom.xml file, right-click the dependency and select Go to Maven Dependency. If you click Open Maven Config on the specific dependency, Aqua will open the dependency's POM file.

   If the duplicate dependency is found, it will be greyed out.

   

   For more information about available options and icons in the Dependency Analyzer window, refer to the reference section.
