Exclude dependency in a profile

Question

I have a maven module which has some dependencies. In a certain profile, I want to exclude some of those dependencies (to be exact, all dependencies with a certain group id). Th

maven is a tool, we can hack it.

• maven runs fine if you have the same artifact + version defined as dependency twice.
• define a profile that eliminates an artifact + version by changing it to another package we already have.

For example, in the pom.xml:

... other pom stuff ...
  
    artifact1
    artifact2
    0.4
    0.5
  

  
    remove-artifact2
    
      artifact1
      artifact1
      0.4
      0.4
    
  

• Now if you install this pom.xml without the profile, artifact1:0.4 and artifact2:0.5 will be the dependency.
• But if you install this pom.xml with the profile mvn -P remove-artifact2 The result pom.xml contains only artifact1:0.4

This comes quite handy during api migration where artifact are renamed and versions are not compatible.
