Hello,
this is not really Mojo specific.
If you build a JAR with maven you can
include the build number or version with filtered resources, filtering
the source code, as a expanded Variable in the Manifest header or by
copy of META-INF/maven/pom.properties. To any of those information you
can then reference to print it out.
This is an example I use (you need to use a class of your project and
add maven group and artifactID):
/** Read program version from Manifest or maven properties. */
private static String getVersion()
{
Class me = MyClass.class;
Package jarPackage = me.getPackage();
if (jarPackage != null)
{
String version = jarPackage.getImplementationVersion();
if (version != null)
{
return version;
}
}
InputStream in =
me.getClassLoader().getResourceAsStream("META-INF/maven/groupID/artifactID/pom.properties");
if (in == null) { return "UNKNOWN";}
try
{
Properties p = new Properties();
p.load(in);
return p.getProperty("version", "UNKNOWN");
}
catch (Exception ignored)
{
return "UNKNOWN";
}
finally
{
try { in.close(); } catch (Exception ignored) { /* ignored
*/ } }
}
Greetings
Bernd
