[FIXED] How to maven release multiple profiles project when redeploys are disabled

Issue

Question: How should I release a maven project which has 2 exclusive profiles when redeploys are disabled on Nexus?

Example (edited): I have a maven project MyArtifact with 2 profiles in pom.xml (P1 and P2) which generates 2 different ears. Each profile configures the maven-ear-plugin to include different modules and auto-generate the application.xml. The generated artifacts are MyArtifact-1.0-P1.ear (2 war modules) and MyArtifact-1.0-P2.ear (3 war modules).

Problem 1 (redeploy to nexus):

1. When I execute "mvn deploy -P P1" everything goes fine (war and pom are deployed to Nexus)
2. When I execute "mvn deploy -P P2" error! Nexus complains about redeploying the pom.xml.

Problem 2 (maven-release-plugin):

When using the maven-release-plugin to release for the multiple profiles, maven do a lot of things (checkout and tag CSM, updates pom versions, turns to tag, commit to CSM, etc...). At least it's not efficient nor practical to have to re-release/re-tag for each profile execution.

Solution

Yeah!

Insted of using profiles, I'am using the maven <executions> feature: 1 execution for each profile i have. Each execution has to generates resources in a different working folder. Each artifact has different classifier. When deploying maven will find the 3 artifacts (pom, ear, ear) and will deploy them to Nexus fine.

Below is the example. Please let me know it you have any problems with it:
