Question

我有几个项目在构建，每一个构建，甚至之前构建的这个，突然在一个新的提交中，我得到了这个-init-debug-args：

总时间:0秒构建步骤'Invoke Ant‘标记为失败的构建存档工件已完成:失败

我已经在netbeans上重建了这个项目，它在本地工作得很好，我有以前在netbeans和jenkins上的相同配置，当它曾经工作时，但它就是不能构建谢谢

新的commit在build-impl.xml中“突然”改变了这一点吗

${platforms.JDK_1.6.home}/bin/java

上面是一个未解析的变量。在看不到其余代码/构建的情况下，我只能猜测:是否有人更改了变量(${platforms.JDK_1.6.home})的硬编码路径？在调用构建时，您可能需要将该变量传递给ant。

或者，您的构建节点(Jenkins主节点或从节点)突然丢失了一个名为${platforms.JDK_1.6.home}的现有环境变量
