How to use maven shade to build jar and war

Question

I'm on a project working with openrdf, and I require the shade plugin to transform my service entries. I would like to build a war and a jar simultaneously, as both usages are possible. However, I cannot get the shade plugin to produce a shaded jar and a shaded war at the same time - shade only invokes on the package type defined in the properties, and binding e.g. the jar plugin to the package phase in order to create a jar next to the war results in an unshaded jar. How can I create both a shaded jar and a shaded war at the same time?

Answer 1

If by "shaded war" you mean just the regular war with all dependencies packed into WEB-INF/lib, then you might just use maven-war-plugin separately and use jar as packaging type. This way shade plugin will work correctly. And .war will be built by plugin.

Below is pom.xml. And here is working example.
