梅文 + Mercurial：执行命令标签时出错

Question

我想使用 Maven-Release-Plugin 发布项目的新版本。

但是，我收到以下错误：

[INFO] Tagging release with the label softsmithy-lib-v0.1...

我尝试运行

/bin/sh -c cd /var/lib/hudson/jobs/SoftSmithy-Utility-Library-Release && hg tag --message '[maven-release-plugin]  copy for tag softsmithy-lib-v0.1' softsmithy-lib-v0.1

并且运行良好！

有什么想法出了什么问题吗？

PS：我在以下网站上注意到： http://maven.apache.org/scm/matrix.html

提到Mercurial标签命令是不支持，但它似乎执行命令（然后以某种方式失败）。如何将 Maven 发布插件与 Mercurial 一起使用？

PPS：这似乎只发生在多模块项目中。单个 POM 项目运行良好。我尝试了 -DpreparationGoals="clean install" 但没有帮助。

Answer 1

我终于找到了解决方案：

所需的父 POM

<groupId>org.sonatype.oss</groupId>
<artifactId>oss-parent</artifactId>
<version>6</version>

使用 Maven Release Plugin 版本 2.0

不幸的是，使用 Mercurial 的多模块项目存在问题。
使用版本 2.1 时，该问题消失了。

解决方法：覆盖项目 POM/项目父 POM 中的版本。

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-release-plugin</artifactId>
  <version>2.1</version>
  <configuration>
    <mavenExecutorId>forked-path</mavenExecutorId>
    <useReleaseProfile>false</useReleaseProfile>
    <arguments>-Psonatype-oss-release</arguments>
  </configuration>
</plugin>

我在这里提出了一个问题：
https://issues.sonatype.org/browse/OSSRH-1388

Answer 2

如果您查看 HgTagCommand.java,它包括一些启动此类异常的地方（即“执行命令时出错”）：

标签[消息]的是：

ScmResult result = HgUtils.execute( branchConsumer, getLogger(), workingDir, branchCmd );
HgScmProviderRepository repository = (HgScmProviderRepository) scmProviderRepository;

if ( !result.isSuccess() )
{
  throw new ScmException( "Error while executing command " + joinCmd( branchCmd ) );
}

关于 看起来与多模块项目兼容，您可以在其中拥有多个 Mercurial 存储库。

Answer 3

我遇到了同样的问题，这是因为 maven release 进行了 3 次提交（至少在 Mercurial 中）：

• 准备发布 制作
• 发布的标签
• 准备下一次开发迭代

有时如果您的项目或发布插件的配置配置不正确，release 卡在第一次提交中。问题是，有时它已经将版本更新到您的 sonatype 服务器中，因此您必须从 sonatype 服务器中删除这个假版本，配置好您的父项目的 pom.xml，编译项目，并再次释放。
这就是我删除项目 bridje-parent 中的错误版本 1.0.0-alpha5 时的样子：

同时删除位于其子模块中的假 release。请记住在发布发布之前在您的scm服务器中提交更改。
如果它对你有用，请投票，这种情况很少发生在我身上。
