Question

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

我在配置中错过了什么？（我希望这是一个配置问题而不是Maven插件相关的bug！:)我的存储库URL似乎没问题（插件之前一直在抱怨，我修复了），我还设置了解析的日期格式（也一直在抱怨），也固定）。

承诺的目标/ 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。

感谢您提出任何建议，我没有搜索过任何内容（也没有提出任何建议;）。

我使用随机项目进行了测试（确切地说是noop）：

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

在maven-changelog-plugin顶部配置pom.xml的{{3}}之后：

  <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>

我能够毫无困难地运行mvn changelog:changelog。我的观点是该插件似乎适用于至少一个项目（随机选择:)。

我真的很想知道hg log --verbose行为是否正确，因为插件似乎抱怨它没有成功运行。如果是这样，你可以尝试在运行Maven时传递-X选项，看看你是否获得了更多有用的信息。

另外，请提供<scm>元素的内容。
