我已将 Maven2 项目配置为从 Mercurial 存储库（可通过 file:// 协议访问）生成更改日志报告，但目标执行失败并显示以下消息：

我在配置中错过了什么？（希望是配置问题而不是Maven插件相关的bug！:) 我的repository URL好像没问题（插件之前一直抱怨，我修好了），我还设置了解析的日期格式（也一直在抱怨，也固定）。

承诺的 target/changelog.xml 根本没有生成。

Maven 2.2.1 Mercurial 1.4.3 Windows XP SP3

mvn scm:changelog命令提供预期的输出。

感谢您的任何建议，我没有搜索任何内容（也没有搜索；）。

我对一个随机项目进行了测试（准确地说是noop）：

hg clone https://noop.googlecode.com/hg/ noop

And after configuring the dateFormat of the maven-changelog-plugin in the top pom.xml:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-changelog-plugin</artifactId>
    <configuration>
      <dateFormat>EEE MMM dd hh:mm:ss yyyy Z</dateFormat>
    </configuration>
  </plugin>

I've been able to run mvn changelog:changelog without troubles. My point is that the plugin seems to work for at least one project (chosen randomly :).

I'd really like to know if hg log --verbose behave correctly as the plugin seems to complain about it not running successfully. If it does, could you try to pass the -X option when running Maven and see if you get more useful information.

Also, please provide the content of your <scm> element.
