 Description   

Using the Gradle-generated .classpath file in Eclipse 3.6 yields the following warning for each referenced library:

Classpath Dependency Validator Message: Classpath entry GRADLE_CACHE/xxx.jar will not be exported or published. Runtime ClassNotFoundExceptions may result.

Eclipse offers a Quick-Fix, which (when applied to each entry) makes the warnings go away. The Quick-Fix modifies the classpath entries so that ...

<classpathentry exported="true" kind="var" path="GRADLE_CACHE/xxx.jar" sourcepath="..."/>

... becomes:

<classpathentry exported="true" kind="var" path="GRADLE_CACHE/xxx.jar" sourcepath="...">
<attributes>
<attribute name="org.eclipse.jst.component.dependency" value="/WEB-INF/lib"/>
</attributes>
</classpathentry>

Workaround:

eclipseClasspath.withXml { xml ->
xml.classpathentry.findAll

{ it.@kind == 'var' }

.each

{ it.appendNode('attributes').appendNode('attribute', [name: 'org.eclipse.jst.component.dependency', value: '/WEB-INF/lib']) }

}

PS: Sorry for spamming you with all the Eclipse related issues lately. The new Eclipse plugin really rocks and it's impressive that all the issues can be easily worked around with a few lines of Groovy code.

As a result of gradle-0.9-rc-3 creating lib classpathentries instead of var, the workaround needs a small fix:

eclipseClasspath.withXml { xml ->
xml.asNode().classpathentry.findAll

{ it.@kind == 'lib' }

.each

{ it.appendNode('attributes').appendNode('attribute', [name: 'org.eclipse.jst.component.dependency', value: '/WEB-INF/lib']) }

}

Just wanted to give a heads up how I'm planning to resolve the issue. For more discussion, see GRADLE-2123.

Plan: Every library/variable dependency (basically, jars) in the .classpath is marked as 'nondependency' by default if the 'eclipse-wtp' plugin is applied. The wtp component file manages and configures the deploy path.

It is a slightly different approach than suggested, e.g. I'm using the 'org.eclipse.jst.component.nondependency' vs 'org.eclipse.jst.component.dependency'. However, this solves the problem and keeps things consistent with the existing approach (e.g. the component file '.settings/org.eclipse.wst.common.component' manages the deployable libraries).

There should be no more warnings. For more discussion see GRADLE-2123
