Getting a source error building Groovy project with Maven

Question

Answer 1

You will have to define project and bind to mavenProject if you are using script rather than inline.

def project = ${project}; // this will bind to the Maven Project property.

likewise

def session = ${session} //will bind to MavenSession

Source - Look for custom properties
