Access maven properties defined in the pom

Question

How do I access maven properties defined in the pom in a normal maven project, and in a maven plugin project?

Answer 1

Use the properties-maven-plugin to write specific pom properties to a file at compile time, and then read that file at run time.

In your pom.xml:

<properties>      <name>${project.name}</name>      <version>${project.version}</version>      <foo>bar</foo> </properties>  <build>     <plugins>         <plugin>             <groupId>org.codehaus.mojo</groupId>             <artifactId>properties-maven-plugin</artifactId>             <version>1.0.0</version>             <executions>                 <execution>                     <phase>generate-resources</phase>                     <goals>                         <goal>write-project-properties</goal>                     </goals>                     <configuration>                         <outputFile>${project.build.outputDirectory}/my.properties</outputFile>                     </configuration>                 </execution>             </executions>         </plugin>     </plugins> </build> 

And then in .java:

java.io.InputStream is = this.getClass().getResourceAsStream("my.properties"); java.util.Properties p = new Properties(); p.load(is); String name = p.getProperty("name"); String version = p.getProperty("version"); String foo = p.getProperty("foo");
