Thanks Kenney. I think what I want is similar to how the pom.properties would normally be
generated by Maven. As in, I want some code / cofiguration that can generate a properties
file with the "version" in it.
For example, I want something to work like
eg.
myApp.properties.template (with contents)
version.from.maven=${maven.pom.version}-${maven.package.build.date}
to produce:
myApp.properties (with contents)
version.from.maven=1.0-SNAPSHOT-2006-05-22
And so I can place in the myApp.properties in the class path and easily read it?

Maven writes a property file in the jar or war at

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" );
}

Guys,
We're using Maven2 and wanted to know the best way to get version information
(including
the SNAPSHOT timestamp, e.g. 1-0-SNAPSHOT-20050622 or sth) into a webapp that
was built
with the "mvn package"?
My guess is that there is a property ${maven.snapshot.version} or something
that we can
use to generate a properties file so that the app can read this information.
Perhaps a
filter copy plugin against one of the goals?
Does anything know any references around this area? Have anyone got examples
they can share?
Thanks,
Mark C
