How to use custom .jar file from a war that is overlaid by maven dependency by removing the core jar

Question

I have a maven3 webapp (war) project that has 3 dependencies. The war dependency is (a 3rd party lib that I have no control over) -- httpclient-4..jar httpcore-4..jar httpcore-nio-4.*.jar

The 3rd party war dependency has a dependency on their defined version of http which is clashing with the later version I need to use.

The following steps occur during a package of my app.

My http jar is copied to /WEB-INF/lib/ The .war dependency which also includes http above is built and overlaid on top of my target Final .war file is created from target

Here,I have managed to exclude/remove the earlier version of http, but now i want to add my own dependency versions of the above jars like: httpclient-4.5.6.jar httpcore-4.3.jar httpcore-nio-4.3.jar

How can i copy while the war is trying to pack my level of change which will not contain 3rd party prev. versions?

--package excluded in bold---

Answer 1

You can on the unpack actually specify excludes on both the artifactItem and the main configuration. You can see an example of this here: Unpacking specific artifacts

This would allow you to before packaging exclude the dependencies that you don't want, from there the packagingIncludes on the maven-war-plugin would pull in all the required items.

Alternatively you could add a step before it that does another maven-dependency-plugin execution that does the copying of your specific artifacts.
