I created a closure to update my eclipse .classpath file to reflect the current dependencies. Maybe this can help:

Closure updateClasspath = { task ->
File eclipseClasspathFile = task.project.file('.classpath')
if (!eclipseClasspathFile.exists())

{ eclipseClasspathFile.append ('<classpath></classpath>') }

ant.copy(file:eclipseClasspathFile, tofile:eclipseClasspathFile.toString() + ".old", overwrite:true)

def classpathXml = new XmlParser().parseText(eclipseClasspathFile.text)

def currentEclipseLibs = classpathXml.classpathentry.findAll

{ it.'@kind'.equals('lib') }


{ classpathXml.remove (it) }

task.project.dependencies.resolve('compile') //vs runtime
for (f in task.project.dependencies.resolveCache.get('compile'))

{ classpathXml.appendNode('classpathentry', [kind:'lib', path:f.toString()]) }


fileWriter = task.project.file('.classpath')
new XmlNodePrinter(new PrintWriter(fileWriter)).print (classpathXml)

A more comprehensive version of an eclipse plugin

Comment by Phil Messenger [ 15/Aug/08 ]

The file I've just attached takes the code submitted by Pieter Smit above and adds some additional features:

  • WTP project file generation in the case of a web project
  • support for sibling / child projects

Hi Phil, I've just returned from my holidays. I'm very much looking forwards to looking at your contribution very soon.

Hi Hans,

this is an updated version of the plugin with a few bug fixes. It's worth noting that at the moment this plugin doesn't generate the Eclipse ".project" file.

Couple of things to note

  • at the moment, WTP (that is Eclipses built in web development tooling) configuration files are generated if the "war" plugin is in use. This probably ought to be a configuration variable.
  • WTP supports the relocation of random source directories to a location under a web root. This is useful when you have configuration files in src/main/conf, but wish to have them deployed by WTP to WEB-INF/classes (so you can run your project in eclipse without needing to generate a war). At the moment this plugin looks for a map called "warResourceMappings" where the key is the source folder relative to project root and the value is the logical location

FWIW, I find the warResourceMappings map useful when actually generating a war:

warResourceMappings = ["src/conf" : "WEB-INF"]

archive_war {
	warResourceMappings.each { mapEntry ->
		zipFileSet( dir: project.file(mapEntry.key), prefix: mapEntry.value )

We submitted tasks for generating Eclipse files. I'm therefore closing this general issue. For the further work we will work with more fine grained issues. I have created a eclipse component for Jira which is supposed to be assigned to Eclipse related issues.
