Maven writes a property file in the jar or war at
/META-INF/maven/<groupId>/<artifactId>/pom.properties.
For jars you can use a classloader to find that resource, but in the case
of a WAR the META-INF is not part of the classpath so you'd have to use
the servlet api to get the path to that file.
Code snippet:
public static String getVersion( String groupId, String artifactId )
throws IOException
{
ClassLoader cl = Thread.currentThread().getContextClassLoader();
Properties props = new Properties();
String propFileName = "META-INF/maven/" + groupId.replace( '.',
'/' ) + "/" + artifactId + "/pom.properties";
InputStream a = cl.getResourceAsStream( propFileName );
if ( a == null )
throw new IOException( "Cannot find '" + propFileName + "'" );
props.load( a );
return props.getProperty( "version" );
}
