# Class EclipseClasspath

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

public abstract class EclipseClasspath extends Object
The build path settings for the generated Eclipse project. Used by the `GenerateEclipseClasspath` task to generate an Eclipse .classpath file.

The following example demonstrates the various configuration options. Keep in mind that all properties have sensible defaults; only configure them explicitly if the defaults don't match your needs.

     plugins {
         id 'java'
         id 'eclipse'
     }

     configurations {
       provided
       someBoringConfig
     }

     eclipse {
       //if you want parts of paths in resulting file to be replaced by variables (files):
       pathVariables 'GRADLE_HOME': file('/best/software/gradle'), 'TOMCAT_HOME': file('../tomcat')

       classpath {
         //you can tweak the classpath of the Eclipse project by adding extra configurations:
         plusConfigurations += [ configurations.provided ]

         //you can also remove configurations from the classpath:
         minusConfigurations += [ configurations.someBoringConfig ]

         //if you want to append extra containers:
         containers 'someFriendlyContainer', 'andYetAnotherContainer'

         //customizing the classes output directory:
         defaultOutputDir = file('build-eclipse')

         //default settings for downloading sources and Javadoc:
         downloadSources = true
         downloadJavadoc = false

         //if you want to expose test classes to dependent projects
         containsTestFixtures = true

         //customizing which Eclipse source directories should be marked as test
         testSourceSets = [sourceSets.test]

         //customizing which dependencies should be marked as test on the project's classpath
         testConfigurations = [configurations.testCompileClasspath, configurations.testRuntimeClasspath]
       }
     }

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

The beforeMerged and whenMerged closures receive a `Classpath` object.

Examples of advanced configuration:

     plugins {
         id 'java'
         id 'eclipse'
     }

     eclipse {
       classpath {
         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 .classpath content is loaded from existing file
           //but before gradle build information is merged
           beforeMerged { classpath ->
             //you can tinker with the Classpath here
           }

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