$ {platforms.JDK_1.6.home} / bin / java“：java.io.IOException：error = 2

Question

我有几个正在构建的项目，每个构建，甚至是以前构建的每个构建，都突然在一个新提交中得到了-init-debug-args：

总时间：0秒构建步骤“调用Ant”将构建标记为失败归档工件已完成：失败

我已经在netbeans上重建了该项目，并且在本地可以完美地工作，我曾经在netbeans和jenkins使用过与以前相同的配置，但是它无法构建，谢谢

新提交是否“突然”在build-impl.xml ：

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

以上是未解决的变量。 没有看到其余的代码/构建，我只能猜测：是否有人将硬编码路径更改为变量（ ${platforms.JDK_1.6.home} ）？ 调用构建时，您可能需要将该变量传递给ant 。

这样，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。
