\nIt is a collection of things found in the offcial maven documentation and postings to the maven user mailing list.
\nBuild in properties<\/b><\/p>\n\n
\nAll elements in the pom.xml, can be referenced with the project. prefix or using pom. as prefix. This list is just an example of some commonly used elements.<\/p>\n\n
\nSimilarly, values in the user’s settings.xml can be referenced using property names with settings. prefix.<\/p>\n\n
\nEnvironment variables can be referenced using the env prefix<\/p>\n\n
\n${java.home}..\/bin\/java.exe<\/li>\n<\/ul>\n
\nAll Java System Properties defined by the JVM.
\nCustom properties in the POM<\/b>
\nUser defined properties in the pom.xml.

\nHow can parent project variables be accessed?
\nYou can use the prefix: ${project.parent}.
\nA 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<\/a> instance.
\nTo access the parent version: ${parent.version}.
\nReflection Properties<\/b>
\nThe pattern ${someX.someY.someZ} can simply sometimes mean getSomeX().getSomeY().getSomeZ(). Thus, properties such as ${project.build.directory} is translated to getProject().getBuild().getDirectory().
