Question

I\'m writing a maven plugin that has a parameter that\'s a String[].

Like this:

/**
* @parameter expression=\"${args}\"
*/
protected String[] args;
<         


        

Answer 1

According to Sonatype's blog here, if you are a plugin developer and

1. use Maven 3

2. and annotate your array/collection type plugin parameter using annotation like:

   /** @parameter expression="${args}" */

In this way, the plugin parameter can be processed by Maven automatically and plugin users can provide the plugin array/collection type parameters via CLI using a comma separated system property like mvn myplugin:mygoal -Dargs=a,b,c
