Attaches sources and javadocs to 3rd party jars in Eclipse

eclipseSourceAndJavadoc.gradle

eclipse {
	classpath.downloadSources = true
	classpath.downloadJavadoc = true
  
	// Classpath entry for Eclipse which changes the order of classpathentries; otherwise no sources for 3rd party jars are shown (http://stackoverflow.com/a/12836295)
	classpath.file {
		withXml { xml ->
			def node = xml.asNode()
			node.remove( node.find { it.@path == 'org.eclipse.jst.j2ee.internal.web.container' } )
			node.appendNode('classpathentry', [ kind: 'con', path: 'org.eclipse.jst.j2ee.internal.web.container', exported: 'true' ])
		}
	}
}
