使用 maven 发布插件时“Git 致命：ref HEAD 不是符号引用”

"Git fatal: ref HEAD is not a symbolic ref" while using maven release plugin

提问by SkyWalker

I get the following error output while running the Maven release plugin prepare step i.e. mvn release:prepare --batch-mode -DreleaseVersion=1.1.2 -DdevelopmentVersion=1.2.0-SNAPSHOT -Dtag=v1.1.2 -Xfrom an Atlassian Bamboo plan. However doing the same in the command line works fine. The full error stack is below.

我在运行 Maven 发布插件准备步骤时收到以下错误输出，即mvn release:prepare --batch-mode -DreleaseVersion=1.1.2 -DdevelopmentVersion=1.2.0-SNAPSHOT -Dtag=v1.1.2 -X来自 Atlassian Bamboo 计划。但是，在命令行中执行相同操作可以正常工作。完整的错误堆栈如下。

Any ideas how can this be solved?

任何想法如何解决？

and this is very weird why is the local development clone output so different from the Bamboo one?

这很奇怪，为什么本地开发克隆输出与 Bamboo 输出如此不同？

The problem in Atlassian Bamboo was solved by un-checking the default setting Use shallow cloneswith description Fetches the shallowest commit history possible. Do not use if your build depends on full repository history. This checkbox is located under Plan Configuration -> Repositories tab -> Git -> Advanced options

Atlassian Bamboo 中的问题通过Use shallow clones使用 description取消选中默认设置来解决Fetches the shallowest commit history possible. Do not use if your build depends on full repository history。此复选框位于计划配置 -> 存储库选项卡 -> Git -> 高级选项

After this all the releases work fine.

在此之后，所有版本都可以正常工作。

I ran into the same error on Jenkins in combination with maven release plugin, we fixed it by going to Additional behaviours, Check out to specific local branch and enter 'master'

我在 Jenkins 与 maven 发布插件结合时遇到了同样的错误，我们通过转到其他行为来修复它，检查到特定的本地分支并输入“master”

I realise this is not a solution but it might give you some direction in where to look.

我意识到这不是一个解决方案，但它可能会给你一些方向。

For Jenkins and GIT add the additional behaviour check out to specific local branchand use the Workspace Cleanup Pluginto clean your workspace to the beginning of your CI job.

对于 Jenkins 和 GIT，添加额外的行为check out to specific local branch并使用Workspace Cleanup Plugin来清理您的工作区到 CI 作业的开始。

Unchecking the Use shallow cloneswas not sufficient in my case (I'm using Bamboo 5.7.2). I needed to also enable Force Clean Buildin the Source Code Checkout task. Enabling the Use shallow cloneswould work for the next execution of the job, but all subsequent execution would result in the same error.

Use shallow clones在我的情况下取消选中是不够的（我使用的是 Bamboo 5.7.2）。我还需要Force Clean Build在 Source Code Checkout 任务中启用。启用Use shallow clones将适用于作业的下一次执行，但所有后续执行都将导致相同的错误。

I have seen this problem under Bamboo used with Maven Release plug-in. I've fixed it by enabling the option 'Force Clean Build' in the 'Source Checkout' task. Bamboo says this might make the build slower, but it works and I didn't seen any significant time increase.

我在 Bamboo 下看到过​​这个问题，用 Maven Release 插件。我通过在“源代码检查”任务中启用“强制清理构建”选项来修复它。Bamboo 说这可能会使构建速度变慢，但它有效并且我没有看到任何显着的时间增加。

I am using a Jenkins Team Project with a Multibranch Project Setup.

我正在使用带有多分支项目设置的 Jenkins 团队项目。

I previously used checkout scmcommand.

我以前使用过checkout scm命令。

Now I am using the following code:

现在我使用以下代码：

checkout([
                 $class: 'GitSCM',
                 branches: scm.branches,
                 extensions: scm.extensions + [[$class: 'CleanCheckout'], [$class: 'LocalBranch', localBranch: 'new']],
                 userRemoteConfigs: scm.userRemoteConfigs
            ])

what worked for me was to call "git checkout -f master" before calling "mvn release"

对我有用的是在调用“mvn release”之前调用“git checkout -f master”

回答by Manu

For us the issue was with maven version specified in the pom file. Corrected the maven version specified in the pom file in accordance with the one in bamboo fixed the issue

对我们来说，问题在于 pom 文件中指定的 maven 版本。更正了pom文件中指定的maven版本，按照bamboo中的一个修复了问题
