Thanks Martin for saving my day! When I was facing this problem today at my new job, I remembered our project and your nifty Ant script. However, I already feared the worst, as I have never really taken a closer look on the Ant script. Can you imagine my joy on finding this blog entry?

Thank you, thank you, thank you. This was the answer to several hours of pain. I tried using but couldn’t figure out how to make it build relative paths. (I’m an Ant newbie and couldn’t figure how to pipe the flattenmapper result to the globmapper…chainedmapper was the missing link)

I suspect dnajam’s errors are due to attempting to load classes from a jar within his project jar. If I understand correctly, that requires a custom classloader. The solution presented here is for referencing external jars placed in a relative path below where the project jar is.

Hi dear Martin Ankerl ,
I have tried your sample code its writing the Manifest.mf file correctly. but while invoking any class file from an external jar, for example StringUtils from apache common-lang. it says java.lang.NoClassDefFoundError: org/apache/commons/lang/StringUtils.
However, commons-lang-2.4.jar is available within the folder name lib at the root of the jar archive as shown in above example. And the Manifest.MF also have an entry similar to following
Class-Path: lib/commons-lang-2.4.jar

Please help
regards

Hey everybody

Why not just use the core Ant task: “manifestclasspath”.

It’s in the AntManual
