# IdeaProject

API Documentation: | `IdeaProject`

Enables fine-tuning project details (*.ipr file) of the IDEA plugin.

Example of use with a blend of all possible properties. Typically you don't have to configure IDEA module directly because Gradle configures it for you.

    import org.gradle.plugins.ide.idea.model.*

    plugins {
        id 'java'
        id 'idea'
    }

    idea {
      project {
        //if you want to set specific jdk and language level
        jdkName = '1.6'
        languageLevel = '1.5'

        //you can update the source wildcards
        wildcards += '!?*.ruby'

        //you can configure the VCS used by the project
        vcs = 'Git'

        //you can change the modules of the *.ipr
        //modules = project(':some-project').idea.module

        //you can change the output file
        outputFile = new File(outputFile.parentFile, 'someBetterName.ipr')

        //you can add project-level libraries
        projectLibraries << new ProjectLibrary(name: "my-library", classes: [new File("path/to/library")])
      }
    }

For tackling edge cases users can perform advanced configuration on resulting XML file. It is also possible to affect the way IDEA plugin merges the existing configuration via beforeMerged and whenMerged closures.

beforeMerged and whenMerged closures receive `Project` object

Examples of advanced configuration:

    plugins {
        id 'java'
        id 'idea'
    }

    idea {
      project {
        ipr {
          //you can tinker with the output *.ipr file before it's written out
          withXml {
            def node = it.asNode()
            node.appendNode('iLove', 'tinkering with the output *.ipr file!')
          }

          //closure executed after *.ipr content is loaded from existing file
          //but before gradle build information is merged
          beforeMerged { project ->
            //you can tinker with Project
          }

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

### Property details

#### `XmlFileContentMerger` `ipr` (read-only)

See `IdeaProject.ipr(org.gradle.api.Action)`

#### `String` `jdkName`

The java version used for defining the project sdk.

See the examples in the docs for `IdeaProject`

Default with `idea` plugin:
  Java version used to run Gradle, for example `'1.6'`
Default with `idea` and `java` plugin:
  Java version used to run Gradle, for example `'1.6'`

#### `IdeaLanguageLevel` `languageLevel`

The default Java language Level to use for this project.

Generally, it isn't recommended to change this value. Instead, you are encouraged to set `sourceCompatibility` and `targetCompatibility` for your Gradle projects which allows you to have full control over language levels in Gradle projects, and means that Gradle and IDEA will use the same settings when compiling.

When not explicitly set, this is calculated as the maximum language level for the Idea modules of this Idea project.

Default with `idea` plugin:
  `JavaVersion.JAVA_1_6`
Default with `idea` and `java` plugin:
  `project.sourceCompatibility`

#### ``List`<`IdeaModule`>` `modules`

Modules for the ipr file.

See the examples in the docs for `IdeaProject`

Default with `idea` plugin:
  `project.allprojects.idea.module`

#### `File` `outputFile`

Output *.ipr

See the examples in the docs for `IdeaProject`.

Default with `idea` plugin:
  ``${project.projectDir}`/`${project.name}`.ipr`

#### ``Set`<`ProjectLibrary`>` `projectLibraries`

The project-level libraries to be added to the IDEA project.

Default with `idea` plugin:
  `[]` (`[scala-library]` with `scala-base` plugin)
Default with `idea` and `java` plugin:
  `[]` (`[scala-library]` with `scala-base` plugin)

#### `JavaVersion` `targetBytecodeVersion`

The target bytecode version to use for this project.

Generally, it isn't recommended to change this value. Instead, you are encouraged to set `sourceCompatibility` and `targetCompatibility` for your Gradle projects which allows you to have full control over language levels in Gradle projects, and means that Gradle and IDEA will use the same settings when compiling.

When `languageLevel` is not explicitly set, this is calculated as the maximum target bytecode version for the Idea modules of this Idea project.

Default with `idea` plugin:
  `JavaVersion.JAVA_1_6`
Default with `idea` and `java` plugin:
  Highest `project.targetCompatibility` value of all java subprojects or `JavaVersion.JAVA_1_6` if no java project found.

#### `String` `vcs`

The vcs for the project.

Values are the same as used in IDEA's “Version Control” preference window (e.g. 'Git', 'Subversion').

See the examples in the docs for `IdeaProject`.

#### ``Set`<`String`>` `wildcards`

The wildcard resource patterns.

See the examples in the docs for `IdeaProject`.

Default with `idea` plugin:
  `['!?*.java', '!?*.groovy']`

### Method details

#### `void` `ipr`(``Action`<? super `XmlFileContentMerger`>` action)

Enables advanced configuration like tinkering with the output XML or affecting the way existing *.ipr content is merged with Gradle build information.

See the examples in the docs for `IdeaProject`

### Script block details

#### `ipr` { }

Enables advanced configuration like tinkering with the output XML or affecting the way existing *.ipr content is merged with Gradle build information.

See the examples in the docs for `IdeaProject`

Delegates to:
  `XmlFileContentMerger` from `ipr`
