Maven variable for reactor root

Question

In a multi-module maven project, is there a variable that points to the root project folder?

• ${project.basedir} points to the current project\'s d

Answer 1

In Maven 3, ${session.executionRootDirectory} is "a variable that always points to the ... directory ... from which the maven command was executed."

Note that this is distinct from a property that gives the top-level root directory of a multi-module project, regardless of where in the directory structure mvn is executed from. Such a property does not exist to my knowledge, but you can use the ${basedir}/.. hack to achieve it. See this thread on maven-users for more details.
