Maven-scm插件:为什么scmRevision没有像预期的那样工作？

Question

我使用的是Maven 3.0.3、Maven/SCM插件(1.5)和Git 1.7.4.1。我想运行一个maven命令来检查git的修订版，但是插件将我的"scmVersion“参数视为分支名称，而不是修订号。例如，如果我配置

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-scm-plugin</artifactId>
    <version>1.5</version>
    <configuration>
      <goals>install</goals>
      <username>username</username>
      <password>password</password>
      <scmVersion>ccaa6881dd1a9312ad44e39eea719f33ec3e8124</scmVersion>
      <scmVersionType>revision</scmVersionType>
    </configuration>
  </plugin>

(我已经验证了上面的版本是有效的版本)，我得到下面的错误。但是，如果我将"scmVersion“更改为分支名称，那么一切都会正常进行。如何将插件配置为从修订版签出？谢谢，-戴夫

可能是单片机连接有问题，试着像这样显式设置connectionType：

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-scm-plugin</artifactId>
    <version>1.5</version>
    <configuration>
      <connectionType>developerConnection</connectionType>
    </configuration>
  </plugin>

您可以使用以下命令验证POM中的URL连接是否有效

mvn scm:validate

正如here所解释的那样：

mvn -DscmConnection="<scm url>" -DscmDeveloperConnection="<scm url>" scm:validate
