Subject Re: package a war which depends on a shaded jar or at jar
Date Sun, 06 Nov 2016 21:44:14 GMT
There are two solutions.

1. Use Maven < 3.3.0
2. Mark the dependencies that are shaded as optional or provided in the
module doing the shading

In the transition from Maven 3.2.x to Maven 3.3.x the internal model was
made read-only which rendered the hacks that the shade plugin has been
using (to remove shaded dependencies) invalid. Consequently, until JvZ
proves that a custom packaging for shaded jars can achieve the same
effective result with a read-only model, you are left with this issue when
using a shaded jar *that is built in the same reactor*
