java - How to exclude a dependency from parent's project in Maven?

Question

For example, I have 2 Maven projects. One is "project-parent". The other is "project-child". Obviously, "project-child" is the sub project of "project-parent".

"project-parent" has a dependency of log4j. But I want to exclude it from the "project-child". Is there a way?

You might say I should move log4j from "project-parent" to "project-child". That is totally correct. But the assumption is I CANNOT modify "project-parent"'s POM.

Thanks in advance.

Answer 1

I think in Maven2 there is no way to achieve this, because this is what POM inheritance is for . However there is one trick that I can think of:

Assume you have the right to upload artifact to your internal artifact repository. You may create an empty JAR, deploy it as log4j:log4j, with a obviously abnormal version (e.g. log4j:log4j:9999 ). Add such dependency in your project-child. Then it will override the dependency of parent to depends on a in-fact-empty JAR.
