Package org.gradle.plugins.ide.idea.model

Class IdeaModule

java.lang.Object
org.gradle.plugins.ide.idea.model.IdeaModule
public class IdeaModule extends Object
Enables fine-tuning module details (*.iml file) of the IDEA plugin.

Example of use with a blend of most possible properties. Typically you don't have to configure this model directly because Gradle configures it for you. 

 apply plugin: 'java'
 apply plugin: 'idea'

 //for the sake of this example, let's introduce a 'performanceTestCompile' configuration
 configurations {
   performanceTestCompile
   performanceTestCompile.extendsFrom(testCompile)
 }

 dependencies {
   //performanceTestCompile "some.interesting:dependency:1.0"
 }

 idea {

   //if you want parts of paths in resulting files (*.iml, etc.) to be replaced by variables (Files)
   pathVariables GRADLE_HOME: file('~/cool-software/gradle')

   module {
     //if for some reason you want to add an extra sourceDirs
     sourceDirs += file('some-extra-source-folder')

     //and some extra test source dirs
     testSourceDirs += file('some-extra-test-dir')

     //and hint to mark some of existing source dirs as generated sources
     generatedSourceDirs += file('some-extra-source-folder')

     //and some extra dirs that should be excluded by IDEA
     excludeDirs += file('some-extra-exclude-dir')

     //if you don't like the name Gradle has chosen
     name = 'some-better-name'

     //if you prefer different output folders
     inheritOutputDirs = false
     outputDir = file('muchBetterOutputDir')
     testOutputDir = file('muchBetterTestOutputDir')

     //if you prefer different SDK than the one inherited from IDEA project
     jdkName = '1.6'

     //put our custom test dependencies onto IDEA's TEST scope
     scopes.TEST.plus += [ configurations.performanceTestCompile ]

     //if 'content root' (as IDEA calls it) of the module is different
     contentRoot = file('my-module-content-root')

     //if you love browsing Javadoc
     downloadJavadoc = true

     //and hate reading sources :)
     downloadSources = false
   }
 }
For tackling edge cases, users can perform advanced configuration on the resulting XML file. It is also possible to affect the way the IDEA plugin merges the existing configuration via beforeMerged and whenMerged closures.

beforeMerged and whenMerged closures receive a Module parameter

Examples of advanced configuration: 

 apply plugin: 'java'
 apply plugin: 'idea'

 idea {
   module {
     iml {
       //if you like to keep *.iml in a secret folder
       generateTo = file('secret-modules-folder')

       //if you want to mess with the resulting XML in whatever way you fancy
       withXml {
         def node = it.asNode()
         node.appendNode('iLoveGradle', 'true')
         node.appendNode('butAlso', 'I find increasing pleasure tinkering with output *.iml contents. Yeah!!!')
       }

       //closure executed after *.iml content is loaded from existing file
       //but before gradle build information is merged
       beforeMerged { module ->
         //if you want skip merging exclude dirs
         module.excludeFolders.clear()
       }

       //closure executed after *.iml content is loaded from existing file
       //and after gradle build information is merged
       whenMerged { module ->
         //you can tinker with Module
       }
     }
   }
 }

  • Constructor Details

  • Method Details

    • getName

      public String getName()
      Configures module name, that is the name of the *.iml file.

      It's optional because the task should configure it correctly for you. By default it will try to use the project.name or prefix it with a part of a project.path to make sure the module name is unique in the scope of a multi-module build. The 'uniqueness' of a module name is required for correct import into IDEA and the task will make sure the name is unique.

      since 1.0-milestone-2

      If your project has problems with unique names it is recommended to always run gradle idea from the root, i.e. for all subprojects. If you run the generation of the IDEA module only for a single subproject then you may have different results because the unique names are calculated based on IDEA modules that are involved in the specific build run.

      If you update the module names then make sure you run gradle idea from the root, e.g. for all subprojects, including generation of IDEA project. The reason is that there may be subprojects that depend on the subproject with amended module name. So you want them to be generated as well because the module dependencies need to refer to the amended project name. Basically, for non-trivial projects it is recommended to always run gradle idea from the root.

      For example see docs for IdeaModule

    • setName

      public void setName(String name)

    • getSourceDirs

      public Set<File> getSourceDirs()
      The directories containing the production sources.

      For example see docs for IdeaModule

      public void setSourceDirs(Set<File> sourceDirs)

    • getGeneratedSourceDirs

      @Incubating public Set<File> getGeneratedSourceDirs()

    • getScopes

      public Map<String,Map<String,Collection<Configuration>>> getScopes()

      Example how to use scopes property to enable 'performanceTestCompile' dependencies in the output *.iml file: 

       apply plugin: 'java'
 apply plugin: 'idea'

 configurations {
   performanceTestCompile
   performanceTestCompile.extendsFrom(testCompile)
 }

 dependencies {
   //performanceTestCompile "some.interesting:dependency:1.0"
 }

 idea {
   module {
     scopes.TEST.plus += [ configurations.performanceTestCompile ]

      Since:
      3.5

    • getOutputFile

      public File getOutputFile()
      Configures output *.iml file. It's optional because the task should configure it correctly for you (including making sure it is unique in the multi-module build). If you really need to change the output file name (or the module name) it is much easier to do it via the moduleName property!

      Please refer to documentation on moduleName property. In IntelliJ IDEA the module name is the same as the name of the *.iml file.

    • setOutputFile

      public void setOutputFile(File newOutputFile)

    • resolveDependencies

      public Set<Dependency> resolveDependencies()
