maven - 使用 maven scm 插件

Question

是否可以使用 maven scm 插件来标记发布，而不必使用发布插件？

我正在尝试执行以下操作，但它不起作用

从 pom 文件中提取

<scm>
  <connection>scm:git:ssh://myuser@gerrit/tutorial.git</connection>
  <developerConnection>scm:git:ssh://myuser@gerrit/tutorial.git</developerConnection>
</scm>

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-scm-plugin</artifactId>
  <version>1.7</version>
  <executions>
    <execution>
      <goals>
        <goal>tag</goal>
      </goals>
    </execution>
  </executions>
</plugin>

从命令行我做

mvn clean install scm:tag

Maven 返回以下错误

[INFO] 'scm:tag' 的一个或多个必需的插件参数无效/缺失

[0] 在插件“maven-scm-plugin”的定义中指定以下内容:

... 值(value)

-或-

在命令行上，指定:'-Dtag=VALUE'

http://maven.apache.org/scm/maven-scm-plugin/tag-mojo.html向您显示两个必需的参数。您需要对它们进行 -D 或将它们放入 pom 中。
