This works for all situations although we mainly use it to include build
information on our demo web apps.
Create a properties file e.g. build.properties where any build variable
properties can be accessed by the java/jstl etc. Have your maven.xml build
update this file using the ant <propertyfile> task. e.g.
<propertyfile file="${project.build.properties}" comment="Updated by
MAVEN build">
<entry key="build.number" value="${project.build.label}"/>
<entry key="build.date" type="date" value="now" pattern="dd/MM/yyyy
HH:mm"/>
<entry key="version" value="${pom.currentVersion}"/>
</propertyfile>

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.
