internal maven properties

This page extracts a few classical values:

• ${project.basedir} 

  • This references to the root folder of the module/project (the location where the current pom.xml file is located)

POM properties referencing useful build locations, with default values defined in the Super POM:

• ${project.build.directory}

  • This represents by default the target folder.
• ${project.build.outputDirectory}
  • This represents by default the target/classes folder.
• ${project.build.testOutputDirectory}
  • This represents by default the target/test-classes folder.
• ${project.build.sourceDirectory}
  • This represents by default the src/main/java folder.
• ${project.build.testSourceDirectory}
  • This represents by default the src/test/java folder.

You can use further properties like the following:

• ${project.build.finalName}
  • This is by default defined as ${project.artifactId}-${project.version}.
• ${project.version}
  • This can be used at locations where you have to write a literal version otherwise, in particular if you are in a multi-modules build for inter modules dependencies.

User Settings

The settings.xml elements could be referenced by using things like this (see also at the Super POM):

• ${settings.localRepository}
  • which references the location of the local repository. This is by default ${home}/.m2/repository.

Values are evaluated in sequence from different syntaxes:

value	evaluation result	common examples
project.* pom.* (deprecated) * (deprecated)	POM content (see POM reference)	${project.version} ${project.build.finalName} ${project.artifactId} ${project.build.directory}
project.basedir pom.basedir (deprecated) basedir (deprecated)	the directory containing the pom.xml file	${project.basedir}
project.baseUri pom.baseUri (deprecated)	the directory containing the pom.xml file as URI	${project.baseUri}
build.timestamp maven.build.timestamp	the UTC timestamp of build start, in yyyy-MM-dd'T'HH:mm:ss'Z' default format, which can be overridden with maven.build.timestamp.format POM property	${maven.build.timestamp}
*	user properties, set from CLI with -Dproperty=value	${skipTests}
*	model properties, such as project properties set in the pom	${any.key}
maven.home	The path to the current Maven home.	${maven.home}
maven.version	The version number of the current Maven execution (since 3.0.4). For example, "3.0.5".	${maven.version}
maven.build.version	The full build version of the current Maven execution (since 3.0.4). For example, "Apache Maven 3.2.2 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19T14:51:28+01:00)".	${maven.build.version}
*	Java system properties (see JDK reference)	${user.home} ${java.home}
env.* *	environment variables	${env.PATH}
settings.*	Local user settings (see settings reference)	${settings.localRepository}
