Maven: Overview for the values of Maven properties

I would like to find out the values of all Maven properties as they apply to some Maven project.
mvn help:system lists OS environment variables and JVM system properties, but no Maven properties.
mvn help:evaluate only works in an interactive mode, that means I have to type a single Maven property, (e.g. ${project.build.outputDirectory}) to get the value of that property.

I'm looking for a way get a full list of all Maven properties and their values.

Solution

  • As a workaround, add this to the <plugins> ... </plugins> section inside your project's pom.xml:

    <plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-antrun-plugin</artifactId>
  <version>1.7</version>
  <executions>
    <execution>
      <phase>validate</phase>
      <goals>
        <goal>run</goal>
      </goals>
      <configuration>
        <tasks>
          <echoproperties />
        </tasks>
      </configuration>
    </execution>
  </executions>
</plugin>

    Now execute mvn validate.
    On the console, prefixed with [echoproperties], there will be the full list of system properties, including those set by Maven such as project.build.outputDirectory, basedir, and settings.localRepository.
