运行maven发布插件时，我得到以下错误输出在Microsoft Visual Studio Team Service（VSO）下准备
--batch-mode -X -Dtag=$(releaseTag) -DreleaseVersion=$(releaseVersion) -DdevelopmentVersion=$(releaseNextSnapshotVersion) clean release:clean release:prepare 在命令行或使用Jenkins（和checkout特定分支）执行相同操作正常。请注意，对我而言，它不是重复的 "Git fatal: ref HEAD is not a symbolic ref" while using maven release plugin因为我没有为VSO找到任何解决方案。
完整错误堆栈如下。任何想法如何解决？
