为什么Eclipse不能将第三方库源文件附加到WTP-faceted Gradle项目？

源文件被下载到Gradle缓存中，源文件的classpath条目看起来没问题，但是Eclipse不会显示第三方库的源文件。

在Eclipse中，生成的.classpath文件有一种奇怪的行为。只需将“Web App Libraries”条目放在类路径文件的底部（-> Java构建路径->顺序和导出）即可解决问题。

最好的解决方案是改进您的gradle.build文件（这样每次通过gradle生成类路径文件时就不需要重新排序构建路径）：

...
eclipse.classpath.file {
    // Classpath entry for Eclipse which changes the order of classpathentries; otherwise no sources for 3rd party jars are shown
    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'])
    }
}
