copied!<p>You can't do it directly as far as I know, but it is pretty common practice to accept a delimited String and split that into an array yourself.</p> <p>For example the <a href="http://maven.apache.org/plugins/maven-site-plugin/" rel="nofollow noreferrer">maven-site-plugin</a> allows you to specify a comma-delimited String of locales, while the <a href="http://scala-tools.org/mvnsites/maven-scala-plugin/usage_run.html" rel="nofollow noreferrer">maven-scala-plugin</a> handles this by allowing you to define the arguments with a pipe separator. You can look at the relevant Mojos to see how the argument is processed.</p> <p>Some example usages below:</p> <p>site-plugin:</p> <pre><code>-Dlocales=enGB,frFR </code></pre> <p>scala-plugin:</p> <pre><code>-DaddArgs=arg1|arg2|arg3 </code></pre> <p>Update: if you want to handle this more elegantly, you could use maven-shared-io to allow definition of an external descriptor file, then pass the descriptor location as a property. This means a single command-line argument can reference a structure of configuration.</p> <p>If this sounds like it might work for you, have a look at this <a href="https://stackoverflow.com/questions/1231561/how-to-share-common-properties-among-several-maven-projects/1265428#1265428">answer</a> that describes how to use external descriptors in the properties plugin, or this <a href="https://stackoverflow.com/questions/495208/how-to-externalize-pieces-of-maven-build-file/1222536#1222536">answer</a> that does similar for the xml-maven-plugin. Or you can just look at the assembly-plugin for ideas.</p>
