mvn one:convert don't work?

Finally, I found that some dependency of maven-one-plugin don't install properly. but fix them this plugin work.

question fixed :

I am working on convert a maven 1 project to maven 2 project so I just run this command at the folder of the project:

mvn one:convert

then get a error:

 [INFO] Internal error in the plugin manager executing goal
  'org.apache.maven.plugins:maven-one-plugin:1.2:convert': 
 Unable to find the mojo 'org.apache.maven.plugins:ma开发者_Go百科ven-one-plugin:1.2:convert' in 
 the plugin 'org.apache.maven.plugins:maven-one-plugin'
 org.apache.maven.model.v3_0_0.PatternSet

Anybody know the reason ? Sorry I just so green on maven and the task is urgent...

Try maven-one-plugin:convert

Please take a look at the plugin manual and check if your configuration matches the required configuration.

http://maven.apache.org/plugins/maven-one-plugin/usage.html

The plugin does exist in central repo

Just wondering if you are running this command using maven 1. If so, can you install maven 2/3 and try?

Edit 1:

Downloaded a sample Maven 1 project from here. Ran mvn convert:one using the latest maven (maven 3). Worked successfully
