I'll do this getting the value from the generated manifest. I build my app with
the javaapp plugin (see maven-plugins.sf.net) and you can access the values
with something like:
public static void main(String[] args) {
Package pkg = Manifest.class.getPackage();
String specVersion = pkg.getSpecificationVersion();
String implVersion = pkg.getImplementationVersion();
}
Note, that the specification version is currently not available using the jar
plugin of Maven, this is fixed in the javaapp plugin. Additionally this works
only, if the classes are really loaded from the jar. Using this code from
within an IDE or a unit test it will fail.
