It probably won't be a perfect fit for you, but this is how I currently expose the svn repository
version using the jar manifest file. From ant you can pull the repository version by execing
'svnversion', then pop the version into the library manifest jar thus:
<!-- target: version -->
<target name="version">
<exec executable="svnversion" outputproperty="svn.version">
<arg value="." />
</exec>
</target>
<!-- target: jar -->
<target name="jar" description="Build jar for development" depends="compile,version">
<jar jarfile="${output.filename}.jar" basedir="${dir.build}">
<manifest>
<attribute name="Implementation-Version" value="${svn.version}" />
</manifest>
</jar>
</target>
Now you can pull the version from the library manifest using something like this:
(Note that AppVersion must be located within the jar in question, otherwise change
'this.getClass()' with '<someClassInTheVersionedJar>.getClass()')
public class AppVersion {
public String getCoreVersion() {
String implementationVersion = this.getClass().getPackage().getImplementationVersion();
if (implementationVersion == null) {
log.info("Implementation version not found, either the jar manifest is incomplete or the
AppVersion class is not contained in a jar file.");
return "Unknown, no implementation version found.";
} else {
return implementationVersion;
}
}
}
Hope this gives you some ideas!
