Getting application version from pom

Question

I have a rest endpoint used to return information about application (so far only app version) But so far this info is hardcoded, and it\'s pretty easy to forget to change it

Answer 1

You better use build-in manifest.

new Manifest(Application.class.getResourceAsStream("/META-INF/manifest.mf"))

For the concrete impl-version:

new Manifest(Application.class.getResourceAsStream("/META-INF/manifest.mf"))
            .getMainAttributes()
            .get(Attributes.Name.IMPLEMENTATION_VERSION)

Using maven do not forget to create the manifest using:

    
        
            
                org.apache.maven.plugins
                maven-jar-plugin
                2.4
                
                    
                        
                            true
