the PMI registered REP's for gainig expertise best processes of project

Maven looks for org.apache.maven.plugins: if you don't specify a groupid for 
the plugin you want to execute.

You need to add a plugin group to your settings.xml file. Go to your 
~/.m2/settings.xml and add the following there:


org.codehaus.mojo


This tells Maven to look at org.codehaus.mojo: for plugins aswell.

Thanks for trying it out Manuel. But I am still getting error trying to

Does it have anything to do with MacOS ? Or any settings in maven 
installation? I didn't change anything on the maven installation though, 
using the default one.


Thanks,
Abhishek

Hi all,

I am new to maven and I was trying to run a simple java program

I created a simple project using:

$ mvn archetype:create -DgroupId=simpleproject
-DartifactId=simpleMavenProject

It contains a default HelloWorld app in simpleproject.App.java
which is what I am trying to run.

NOTE: If I use the full name of the exec-maven plugin, it is working.
