Intro

Because I couldn't find a clear overview of which properties are availabe in maven2 I started this page. It is a collection of things found in the offcial maven documentation and postings to the maven user mailing list.

Note: In Maven 3.0, all pom.* properties are deprecated. Use project.* instead!

Built-in properties

Pom/Project properties

All elements in the pom.xml, can be referenced with the project. prefix. This list is just an example of some commonly used elements. (deprecated: {pom.} prefix)

Local user settings

Similarly, values in the user's settings.xml can be referenced using property names with settings. prefix.

Environment variables

Environment variables can be referenced using the env prefix

Java system properties

All Java System Properties defined by the JVM.

Custom properties in the POM

User defined properties in the pom.xml.

<project>
...
  <properties>
     <my.filter.value>hello</my.filter.value>
  </properties>
...
</project>

Parent Project variables

How 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}.

Reflection Properties

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().
