if you inserted the above XML fragment in your pom.xmlHow can parent project variables be accessed?
You can use the prefix: ${project.parent
}.
A good way to determine possible variables is to have a look directly at the API. I‘m currently using Maven 2.2.1, and to access the Parent you can use ${project.parent
}. This will return an org.apache.maven.project.MavenProject instance.
To access the parent version: ${parent.version
}.
The pattern ${someX.someY.someZ
} can simply sometimes mean getSomeX().getSomeY().getSomeZ()
. Thus, properties such as ${project.build.directory
} is translated to getProject().getBuild().getDirectory()
.
