在Jenkins上获取git存储库时出错（不是每次）

我有Jenkins的工作来运行单元测试。每隔10分钟，它会检查git存储库中是否有任何新的更改。如果发现一些变化，它将运行测试

此错误每2-3次生成发生一次。其他版本也可以

出现错误的日志：

我不明白为什么会发生这种错误。我想消除它。现在jenkins作业向我显示了假错误（不是测试状态的结果）

编辑。 我注意到，当我自己在工作区目录中执行最后一个git fetch命令时，它会依次返回两个不同的结果（我不确定是否与上述错误有关）：

---

您的Jenkins构建命令是什么？？？它是一个shell命令：

/usr/local/bin/prove-j3--lib--timer--nocount--formatter=TAP:：formatter:：JUnit$WORKSPACE/t>$WORKSPACE/build/testreports/Jenkins-${JOB_NAME}-JUnit.xml

，但我认为错误在构建阶段之前，而是在scm操作期间。这与中描述的问题相同（未解决）。我删除了整个工作区并再次克隆了git项目。所以现在新的构建是可以的。但这是一个很好的解决办法。
