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.

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
