java - 进程 'Gradle Test Executor' 以非零退出值 29 结束

Question

我的一个测试任务失败了，但在任何日志中都没有任何明显的错误消息:

:midonet-cluster:测试失败

失败:构建失败，出现异常。

* 出了什么问题: 任务“:midonet-cluster:test”执行失败。

Process 'Gradle Test Executor 12' finished with non-zero exit value 29

这是堆栈跟踪:

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':midonet-cluster:test'.

没有失败的测试。

这似乎是一些资源问题，因为当我减少测试数量时问题就消失了(通过从测试任务中排除包)。排除哪些测试并不重要。

如果禁用 gradle 守护进程，问题仍然存在。

Gradel 版本是 3.5.1，但问题仍然存在于 4.5.1。

在 Debug模式下运行任务不会显示任何新内容。我们可以检查失败的进程是否移至“STARTED”状态，然后移至“FAILED”状态。

这总是发生在具有 80GB 内存的 ubuntu16.04 机器上，有时在我的 16GB 内存的 MAC 上。

任何解决或调试此问题的帮助将不胜感激!

非常感谢。

Answer 1

原来是主代码调用的System.exit()，因为一些测试没有关闭后台服务。我相信 gradle 可能会更好地处理这个问题:)
