Maven already has a solution to do what you want   Get MavenProject from just the POM xml - pom parser   btw  first hit at google search     Model model   null  FileReader reader   null  MavenXpp3Reader mavenreader   new MavenXpp3Reader     try        reader   new FileReader pomfile       lt -- pomfile is your pom xml      model   mavenreader read reader        model setPomFile pomfile    catch Exception ex           do something better here      ex printStackTrace      MavenProject project   new MavenProject model   project getProperties       lt -- thats what you need

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    lt properties gt        lt name gt   project name  lt  name gt        lt version gt   project version  lt  version gt        lt foo gt bar lt  foo gt   lt  properties gt    lt build gt       lt plugins gt           lt plugin gt               lt groupId gt org codehaus mojo lt  groupId gt               lt artifactId gt properties-maven-plugin lt  artifactId gt               lt version gt 1 0 0 lt  version gt               lt executions gt                   lt execution gt                       lt phase gt generate-resources lt  phase gt                       lt goals gt                           lt goal gt write-project-properties lt  goal gt                       lt  goals gt                       lt configuration gt                           lt outputFile gt   project build outputDirectory  my properties lt  outputFile gt                       lt  configuration gt                   lt  execution gt               lt  executions gt           lt  plugin gt       lt  plugins gt   lt  build gt    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

This can be done with standard java properties in combination with the maven-resource-plugin with enabled filtering on properties    For more info see http   maven apache org plugins maven-resources-plugin examples filter html  This will work for standard maven project as for plugin projects
