是否可以使用Maven SCM插件进行版本标记而不必使用发布插件？
我正在尝试做以下操作，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>
而从命令行中，我执行以下操作：
mvn clean install scm:tag
Maven报错如下：
[INFO] 对于'scm:tag'，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：
... VALUE
-或-
在命令行上指定：'-Dtag=VALUE'
