Description
When the maven-remote-resources-plugin:process goal is integrated into the lifecycle of a parent project in a multi-module reactor build, the goal fails with an NPE if dependency version ranges are used in the child modules. Additionally, "runOnlyAtExecutionRoot" option needs to be set to true in order to recreate the problem. Please see the attached test project that demonstrates the problem.
Full exception trace is as follows:
