EclipseProject - Gradle DSL Version 2.14.1

# EclipseProject

API Documentation: | `EclipseProject`

Enables fine-tuning project details (.project file) of the Eclipse plugin

Example of use with a blend of all possible properties. Bear in mind that usually you don't have configure eclipse project directly because Gradle configures it for free!

    apply plugin: 'java'
    apply plugin: 'eclipse'

    eclipse {
      project {
        //if you don't like the name Gradle has chosen
        name = 'someBetterName'

        //if you want to specify the Eclipse project's comment
        comment = 'Very interesting top secret project'

        //if you want to append some extra referenced projects in a declarative fashion:
        referencedProjects 'someProject', 'someOtherProject'
        //if you want to assign referenced projects
        referencedProjects = ['someProject'] as Set

        //if you want to append some extra natures in a declarative fashion:
        natures 'some.extra.eclipse.nature', 'some.another.interesting.nature'
        //if you want to assign natures in a groovy fashion:
        natures = ['some.extra.eclipse.nature', 'some.another.interesting.nature']

        //if you want to append some extra build command:
        buildCommand 'buildThisLovelyProject'
        //if you want to append a build command with parameters:
        buildCommand 'buildItWithTheArguments', argumentOne: "I'm first", argumentTwo: "I'm second"

        //if you want to create an extra link in the eclipse project,
        //by location uri:
        linkedResource name: 'someLinkByLocationUri', type: 'someLinkType', locationUri: 'file://someUri'
        //by location:
        linkedResource name: 'someLinkByLocation', type: 'someLinkType', location: '/some/location'
      }
    }

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

beforeMerged and whenMerged closures receive `Project` object

Examples of advanced configuration:

    apply plugin: 'java'
    apply plugin: 'eclipse'

    eclipse {
      project {

        file {
          //if you want to mess with the resulting XML in whatever way you fancy
          withXml {
            def node = it.asNode()
            node.appendNode('xml', 'is what I love')
          }

          //closure executed after .project content is loaded from existing file
          //but before gradle build information is merged
          beforeMerged { project ->
            //if you want skip merging natures... (a very abstract example)
            project.natures.clear()
          }

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

### Properties

Property | Description
`buildCommands` | The build commands to be added to this Eclipse project.
`comment` | A comment used for the eclipse project. By default it will be configured to project.description
`file` | See `EclipseProject.file{}`
`linkedResources` | The linked resources to be added to this Eclipse project.
`name` | Configures eclipse project name. It is 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 moduleName is unique in the scope of a multi-module build. The 'uniqueness' of a module name is required for correct import into Eclipse and the task will make sure the name is unique.
`natures` | The natures to be added to this Eclipse project.
`referencedProjects` | The referenced projects of this Eclipse project (*not*: java build path project references).

### Methods

Method | Description
`buildCommand(buildCommand)` | Adds a build command to the eclipse project.
`buildCommand(args, buildCommand)` | Adds a build command with arguments to the eclipse project.
`linkedResource(args)` | Adds a resource link (aka 'source link') to the eclipse project.
`natures(natures)` | Appends natures entries to the eclipse project.
`referencedProjects(referencedProjects)` | The referenced projects of this Eclipse project (*not*: java build path project references).

### Script blocks

Block | Description
`file` | Enables advanced configuration like tinkering with the output XML or affecting the way existing .project content is merged with gradle build information

### Property details

#### ``List`<`BuildCommand`>` `buildCommands`

The build commands to be added to this Eclipse project.

For example see docs for `EclipseProject`

Default with `eclipse` and `java` plugins:
  Java builder, plus Scala and Web builders as appropriate.

#### `String` `comment`

A comment used for the eclipse project. By default it will be configured to project.description

For example see docs for `EclipseProject`

Default with `eclipse` and `java` plugins:
  `project.description`

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

See `EclipseProject.file{}`

#### ``Set`<`Link`>` `linkedResources`

The linked resources to be added to this Eclipse project.

For example see docs for `EclipseProject`

Default with `eclipse` and `java` plugins:
  []

#### `String` `name`

Configures eclipse project name. It is 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 moduleName is unique in the scope of a multi-module build. The 'uniqueness' of a module name is required for correct import into Eclipse and the task will make sure the name is unique.

The logic that makes sure project names are unique is available since 1.0-milestone-2

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

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

For example see docs for `EclipseProject`

Default with `eclipse` and `java` plugins:
  ``${project.name}` (sometimes prefixed with parts of `${project.path}` to guarantee uniqeness)`

#### ``List`<`String`>` `natures`

The natures to be added to this Eclipse project.

For example see docs for `EclipseProject`

Default with `eclipse` and `java` plugins:
  Java nature, plus Groovy, Scala and Web natures as appropriate.

#### ``Set`<`String`>` `referencedProjects`

The referenced projects of this Eclipse project (*not*: java build path project references).

Referencing projects does not mean adding a build path dependencies between them! If you need to configure a build path dependency use Gradle's dependencies section or eclipse.classpath.whenMerged { classpath -> ... to manipulate the classpath entries

For example see docs for `EclipseProject`

Default with `eclipse` and `java` plugins:
  []

### Method details

#### `void` `buildCommand`(`String` buildCommand)

Adds a build command to the eclipse project.

For example see docs for `EclipseProject`

#### `void` `buildCommand`(`Map` args, `String` buildCommand)

Adds a build command with arguments to the eclipse project.

For example see docs for `EclipseProject`

#### `void` `linkedResource`(``Map`<`String`, `String`>` args)

Adds a resource link (aka 'source link') to the eclipse project.

For example see docs for `EclipseProject`

Appends natures entries to the eclipse project.

For example see docs for `EclipseProject`

#### `void` `referencedProjects`(``String`...` referencedProjects)

The referenced projects of this Eclipse project (*not*: java build path project references).

Referencing projects does not mean adding a build path dependencies between them! If you need to configure a build path dependency use Gradle's dependencies section or eclipse.classpath.whenMerged { classpath -> ... to manipulate the classpath entries

### Script block details

The object passed to whenMerged{} and beforeMerged{} closures is of type `Project`

For example see docs for `EclipseProject`

Delegates to:
  `XmlFileContentMerger` from `file`
