------------------------------------------------------------------------
The plugin 'org.apache.maven.plugins:maven-tomcat-plugin' does not exist
or no valid version could be found
提示说maven-tomcat-plugin' 插件不存在，仔细查看一下pom文件，发现里面配置了 ：
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>tomcat-maven-plugin</artifactId>
</plugin>
，
那为什么还报错。
仔细观察，发现mvn并没有采用pom文件里面的配置来下载tomcat-maven-plugin，而是自以为是的去下载maven-tomcat-plugin' ，关于这个问题很多帖子上都反映过，如下：
Hi,
I'm trying to use tomcat-maven-plugin from
http://mojo.codehaus.org/tomcat-maven-plugin/
But when I type mvn tomcat:deploy, i get
----------------------------------------------------------------------------
Building Design Council

----------------------------------------------------------------------------
Searching repository for plugin with prefix: 'tomcat'.
project-execute : myapp:myapp:war:0.1.0-SNAPSHOT (

Diagnosis: The plugin 'org.apache.maven.plugins:maven-tomcat-plugin'

FATAL ERROR: Error executing Maven for a project
org.apache.maven.lifecycle.LifecycleExecutionExcep tion: The plugin
'*org.apache.maven.plugins:maven-tomcat-plugin*' does not exist or no
valid version could be found
But I don't even have 'maven-tomcat-plugin' configured in my pom.xml!
I've tried removing whole repository, but the problem persists. I'm just
wondering if there is a way to make maven use a specific plugin for the
shortname tomcat?
这个老外也是这样。
后来，找到一个帖子，
hey, I resolver the conflict by calling:
mvn org.codehaus.mojo:tomcat-maven-plugin:deploy
'Invalid task 'kasza': you must specify a valid lifecycle phase, or a
goal in the format plugin:goal or
*pluginGroupIdluginArtifactIdluginVersion:goal *'
知道了，可以通过指定完全限定名称来解决这个问题。
所以 只要将上面命令中的 tomcat 替换成 org.codehaus.mojo:tomcat-maven-plugin 就可以解决问题了。
