getting parent directory of ${basedir} from maven

Question

Is there way to get parent directory for ${basedir} in my pom.xml? Currently I have

<earSourceDirectory>${basedir}/EAR/src/main/resources</earSourceDirectory> 

but I need to access parent directory of basedir as my resources lies in different maven project.

How can I get the parent folder of ${basedir}?

Answer 1

${project.basedir}/../

However, access resources in a different module is something I try to avoid. I'd suggest using the unpack goal of the maven-dependency-plugin.

Answer 2

In the children:

<properties>
    <main.basedir>${project.parent.basedir}</main.basedir>
</properties>

In the grandchildren:

<properties>
    <main.basedir>${project.parent.parent.basedir}</main.basedir>
</properties>
