源代码在 Gradle 缓存中下载，源文件的类路径条目看起来没问题，但 Eclipse 不显示第 3 方库的源文件。

这是 Eclipse 中生成的 .classpath 文件的一种奇怪行为。只需将“Web App Libraries”条目放在类路径文件的底部（-> Java Build Path -> Order and Export）。

最好的解决方案是增强你的 gradle.build 文件（这样你就不需要在每次通过 gradle 生成类路径文件时重新排序你的构建路径）：

...
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'])
    }
}
