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:

     ${project.name}
     ${project.version}
     bar



    
        
            org.codehaus.mojo
            properties-maven-plugin
            1.0.0
            
                
                    generate-resources
                    
                        write-project-properties
                    
                    
                        ${project.build.outputDirectory}/my.properties
                    
                
            
        
    

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");
