mvn 发布：准备不提交对 pom.xml 的更改

我正在尝试发布一个 Jenkins 插件（隐藏通知程序）使用 Maven 并面临发布插件的问题。

mvn clean release:prepare

运行完成时没有错误，但无法在我的本地 git 存储库中提交更改的 pom.xml 。尽管它确实标记了我试图发布版本 1.0.2 的分支的 HEAD。这是我的本地分支在准备发布之前的样子

* df60768 (HEAD, origin/develop, develop) upgraded parent pom to version 1.498
* 792766a added distribution management section to pom.xml and amended readme.md 

这就是它之后的样子

* df60768 (HEAD, tag: stashNotifier-1.0.2, origin/develop, develop) upgraded parent pom to version 1.498
* 792766a added distribution management section to pom.xml and amended readme.md 

不幸的是，pom.xml 已经包含了下一个开发版本，这又会导致后续的release:perform 发布该快照版本。

从maven的命令输出来看，它几乎看起来省略了git commit命令：

我正在运行 Maven 3.0.5（没有 --dry-run 或 -DpushChanges=false）。以下是我的有效 pom 的相关（我认为）部分：

[...]

   <connection>scm:git:git://github.com/jenkinsci/stashnotifier-plugin.git</connection>

我究竟做错了什么？

我通过更新 git scm 提供程序依赖项（而不是发布插件版本）解决了我这边的问题（运行 maven 3.0.5）：

<build>
  <plugins>
    <plugin>
      <artifactId>maven-release-plugin</artifactId>
      <version>2.4.2</version>
      <dependencies>
        <dependency>
          <groupId>org.apache.maven.scm</groupId>
          <artifactId>maven-scm-provider-gitexe</artifactId>
          <version>1.8.1</version>
        </dependency>
       </dependencies>
      </plugin>
    </plugins>
</build>

git scm 1.8.1 版本正确地进行了 git 提交（使用准备和回滚目标进行了测试）。

编辑：根据您的环境，可能需要不同版本的 maven-release-plugin 和 maven-scm-provider-gitexe。请参阅评论以进行更多讨论。
