java - Maven 在使用 tomcat7-maven-plugin 时找不到 tomcat7 目标

Question

我在尝试使用 maven tomcat 插件将我的 webapp 部署设置为 tomcat 7 时遇到问题。

设置.xml:

<server>
  <id>server</id>
  <username>admin</username>
  <password>password</password>
</server>

pom.xml:

<plugin>
  <groupId>org.apache.tomcat.maven</groupId>
  <artifactId>tomcat7-maven-plugin</artifactId>
  <version>2.2</version>
  <configuration>
    <server>server</server>
    <url>http://localhost:8080/manager/text</url>
    <path>/myapp</path>
  </configuration>
</plugin>

当我开始输入 mvn tom<tab> 时自动完成只建议我 mvn tomcat: .

mvn tomcat:list 的输出是:

[INFO] Scanning for projects...

看起来 tomcat6-maven-plugin 确实在使用中。

mvn tomcat7:list 的输出是:

[INFO] Scanning for projects...
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD FAILURE

我使用的是 Ubuntu 13.10，所有软件都是通过存储库安装的。

据我所知，tomcat7 mojo 还没有实现一些目标，mvn tomcat7:list 就是其中之一。 mvn tomcat6:list 可用于 tomcat6 mojo。
