Maven release:prepare fails to commit tag
提问by Peter N. Steinmetz
Attempting to perform a release on a maven project, which has successfully released before.
尝试对之前已成功发布的 Maven 项目执行发布。
When I perform mvn release:prepareI am prompted for the release tags and the new snapshot tags and the project builds.
当我执行mvn release:prepare时，系统会提示我输入发布标签和新快照标签以及项目构建。
But when it attempts to push to the remote, I get
但是当它尝试推送到遥控器时，我得到
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-release-plugin:2.0:prepare (default-cli) on project NeuralAnalysis: Unable to tag SCM
[ERROR] Provider message:
[ERROR] The git-push command failed.
[ERROR] Command output:

And indeed, attempting to perform git push ssh://[email protected]/NeuralAnalysis.git NeuralAnalysis-1.5.6manually, also exits with the same complaint.
事实上，尝试git push ssh://[email protected]/NeuralAnalysis.git NeuralAnalysis-1.5.6手动执行，也会以同样的抱怨退出。
Performing git pullsays 'Already up-to-date'. git branchshows I am on the 'master'. git push origingives 'Everything up-to-date'.
表演git pull说“已经是最新的”。git branch显示我在“主人”上。git push origin给出“一切都是最新的”。
Looking at the repository using Tower shows that 'master', 'origin/master' and 'NeuralAnalysis-1.5.6' are all the same and on the last commit. The working directory contains release.properties and pom.xml.releaseBackup files.
使用 Tower 查看存储库显示“master”、“origin/master”和“NeuralAnalysis-1.5.6”都是相同的，并且是最后一次提交。工作目录包含 release.properties 和 pom.xml.releaseBackup 文件。
It looks to me like everything is fine with the repository overall.
在我看来，整个存储库的一切都很好。
回答by Peter N. Steinmetz
Turns out it was a remote tag with the same name, as suggested by VonC in the comment. This was likely created by some previously aborted release.
事实证明，这是一个同名的远程标签，正如 VonC 在评论中所建议的那样。这可能是由一些先前中止的版本造成的。
Although I found the remote tag by manually inspecting the refs/tags directory on the remote repository, git ls-remote --tagswill show them as well and the git push --verbosewill also show more about the problem in general.
虽然我通过手动检查远程存储库上的 refs/tags 目录找到了远程标签，但git ls-remote --tags也会显示它们，并且git push --verbose还会显示更多关于一般问题的信息。
To fix this, first retrieve the remote tags with git fetch --tags.
要解决此问题，请首先使用 检索远程标签git fetch --tags。
One way to perform the next step is then to simply bypass that release tag by updating the pom.xml to have a higher -SNAPSHOT version (including any references in the same project by other modules to that snapshot), check these in, and do mvn release:clean; mvn release:prepareover again.
执行下一步的一种方法是通过更新 pom.xml 以具有更高的 -SNAPSHOT 版本（包括同一项目中其他模块对该快照的任何引用）来简单地绕过该发布标记，检查这些，然后执行mvn release:clean; mvn release:prepare再次。
