## [Groovy] Class EclipseWtpComponent

- org.gradle.plugins.ide.eclipse.model.EclipseWtpComponent

- Enables fine-tuning wtp component details of the Eclipse plugin

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

       apply plugin: 'java'
       apply plugin: 'war'
       apply plugin: 'eclipse-wtp'

       configurations {
         someInterestingConfiguration
         anotherConfiguration
       }

       eclipse {

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

         wtp {
           component {
             //you can configure the context path:
             contextPath = 'someContextPath'

             //you can configure the deployName:
             deployName = 'killerApp'

             //you can alter the wb-resource elements. sourceDirs is a ConventionProperty.
             //non-existing source dirs won't be added to the component file.
             sourceDirs += file('someExtraFolder')

             //you can alter the files are to be transformed into dependent-module elements:
             plusConfigurations += [ configurations.someInterestingConfiguration ]

             //or whose files are to be excluded from dependent-module elements:
             minusConfigurations += configurations.anotherConfiguration

             //you can add a wb-resource elements; mandatory keys: 'sourcePath', 'deployPath':
             //if sourcePath points to non-existing folder it will *not* be added.
             resource sourcePath: 'extra/resource', deployPath: 'deployment/resource'

             //you can add a wb-property elements; mandatory keys: 'name', 'value':
             property name: 'moodOfTheDay', value: ':-D'
           }
         }
       }

  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 WtpComponent object

  Examples of advanced configuration:

       apply plugin: 'java'
       apply plugin: 'war'
       apply plugin: 'eclipse-wtp'

       eclipse {

         wtp {
           component {
             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 wtp component file content is loaded from existing file
               //but before gradle build information is merged
               beforeMerged { wtpComponent ->
                 //tinker with WtpComponent here
               }

               //closure executed after wtp component file content is loaded from existing file
               //and after gradle build information is merged
               whenMerged { wtpComponent ->
                 //you can tinker with the WtpComponent here
               }
             }
           }
         }
       }

- - ### Property Detail

    - #### String classesDeployPath

      The deploy path for classes.

      For examples see docs for EclipseWtp

    - #### String contextPath

      The context path for the web application

      For examples see docs for EclipseWtp

    - #### String deployName

      The deploy name to be used.

      For examples see docs for EclipseWtp

    - #### final XmlFileContentMerger file

      See file(Closure)

    - #### Set<Configuration> libConfigurations

      The configurations whose files are to be transformed into dependent-module elements with a deploy path of #libDeployPath.

      For examples see docs for EclipseWtp

    - #### String libDeployPath

      The deploy path for libraries.

      For examples see docs for EclipseWtp

    - #### Set<Configuration> minusConfigurations

      The configurations whose files are to be excluded from dependent-module elements.

      For examples see docs for EclipseWtp

    - #### Map<String, File> pathVariables

      The variables to be used for replacing absolute path in dependent-module elements.

      For examples see docs for EclipseModel

    - #### final Project project

    - #### List<WbProperty> properties

      Additional property elements.

      For examples see docs for EclipseWtp

    - #### List<WbResource> resources

      ConventionProperty for additional wb-resource elements.

      For examples see docs for EclipseWtp

      Only resources that link to an existing directory (`WbResource#sourcePath`) will be added to the wtp component file. The reason is that non-existing resource directory declarations lead to errors when project is imported into Eclipse.

    - #### Set<Configuration> rootConfigurations

      The configurations whose files are to be transformed into dependent-module elements with a deploy path of '/'.

      For examples see docs for EclipseWtp

    - #### Set<File> sourceDirs

      ConventionProperty for the source directories to be transformed into wb-resource elements.

      For examples see docs for EclipseWtp

      Only source dirs that exist will be added to the wtp component file. Non-existing resource directory declarations lead to errors when project is imported into Eclipse.
