我正在使用 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。因此，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>

（我已经验证以上是有效的修订版），我收到以下错误。但是，如果我将“scmVersion”更改为分支名称，那么一切正常。如何配置插件以从修订中签出？谢谢， - 戴夫

可能是 SCM 连接有问题，尝试像这样显式设置 connectionType：

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

您可以使用命令验证 POM 中的 URL 连接是否有效
mvn scm:validate

正如这里所解释的：

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