    copied!<p>I don't know <em>exactly</em> why the <code>${project.parent.basedir}</code> is not "available" from AntRun, maybe it's just not supported (see <a href="http://jira.codehaus.org/browse/MNG-3597" rel="noreferrer">http://jira.codehaus.org/browse/MNG-3597</a>).</p> <p>Here is an horrible workaround using gmaven:</p> <pre><code>&lt;plugin&gt; &lt;groupId&gt;org.codehaus.gmaven&lt;/groupId&gt; &lt;artifactId&gt;gmaven-plugin&lt;/artifactId&gt; &lt;version&gt;1.3&lt;/version&gt; &lt;executions&gt; &lt;execution&gt; &lt;id&gt;set-custom-property&lt;/id&gt; &lt;phase&gt;validate&lt;/phase&gt; &lt;goals&gt; &lt;goal&gt;execute&lt;/goal&gt; &lt;/goals&gt; &lt;configuration&gt; &lt;source&gt; project.properties.setProperty('main.basedir', project.parent.basedir.toString()) &lt;/source&gt; &lt;/configuration&gt; &lt;/execution&gt; &lt;/executions&gt; &lt;/plugin&gt; &lt;plugin&gt; &lt;artifactId&gt;maven-antrun-plugin&lt;/artifactId&gt; &lt;version&gt;1.6&lt;/version&gt; &lt;executions&gt; &lt;execution&gt; &lt;id&gt;render-parameter-sql&lt;/id&gt; &lt;phase&gt;validate&lt;/phase&gt; &lt;goals&gt; &lt;goal&gt;run&lt;/goal&gt; &lt;/goals&gt; &lt;configuration&gt; &lt;target&gt; &lt;echo&gt;project.artifactId : ${project.artifactId}&lt;/echo&gt; &lt;echo&gt;project.parent.basedir : ${project.parent.basedir}&lt;/echo&gt; &lt;echo&gt;main.basedir : ${main.basedir}&lt;/echo&gt; &lt;echo&gt;project.basedir : ${project.basedir}&lt;/echo&gt; &lt;echo&gt;project.build.directory : ${project.build.directory}&lt;/echo&gt; &lt;/target&gt; &lt;/configuration&gt; &lt;/execution&gt; &lt;/executions&gt; &lt;/plugin&gt; </code></pre> <p>I'm not proud of it, but it kinda "works" (if a string representation of the path to the parent basedir is ok for you):</p> <pre> $ mvn validate [INFO] Scanning for projects... ... [INFO] --- maven-antrun-plugin:1.6:run (render-parameter-sql) @ Q4040778 --- [INFO] Executing tasks main: [echo] project.artifactId : Q4040778 [echo] project.parent.basedir : ${project.parent.basedir} <b>[echo] main.basedir : /home/pascal/Projects/stackoverflow</b> [echo] project.basedir : /home/pascal/Projects/stackoverflow/Q4040778 [echo] project.build.directory : /home/pascal/Projects/stackoverflow/Q4040778/target [INFO] Executed tasks ... </pre> <p>But I need to say that what you want to do (<em>from this module I need the root of the parent to reach other modules</em>) is a <strong>bad practice</strong>, modules should be self contained and not tightly coupled.</p> <p>I do not recommend using what I posted :)</p>
