# Class EclipseProject

java.lang.Object
org.gradle.plugins.ide.eclipse.model.EclipseProject

public abstract class EclipseProject extends Object
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!

    plugins {
        id 'java'
        id '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'

        //if you don't want any node_modules folder to appear in Eclipse, you can filter it out:
        resourceFilter {
          appliesTo = 'FOLDERS'
          type = 'EXCLUDE_ALL'
          matcher {
            id = 'org.eclipse.ui.ide.multiFilter'
            arguments = '1.0-name-matches-false-false-node_modules'
          }
        }
      }
    }

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:

    plugins {
        id 'java'
        id '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
          }
        }
      }
    }

- ## Method Details

  - ### getName

    public String getName()

  - ### setName

    public void setName(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.
