Question

Example:

I would hope and expect the following pom to deploy both profileResources and commonResources when the “profile” profile is active, but it deploys only profileResources. What can I do to achieve the desired effect?

Answer 1

Try adding combine.children="append" to the resources element in the non-profile plugin- I think it’s messing up because the default behaviour means the profile settings will override anything with the same name higher up the tree. See http://maven.apache.org/pom.html#Plugins for details on merging/appending attributes.
