• webapp-reference/pom.xml
• webapp-reference/webapp-reference-core
• webapp-reference/webapp-reference-web (depends on core)

When I create a new project from a maven pom, IDEA creates the correct module dependency from my web module to the core. Everything compiles right out of the box. If I do a maven synchronization and then a full build, the inter-module dependency is lost and I get a number of compilations errors (which can be easily fixed by manually adding the aforementioned module dependency on core).

I've attached screenshots of the process.

Notes:

• The project is available publicly via subversion: https://logan.carbonfive.com/svn/public/webapp-reference/tags/idea-multimodule-dependencies/
• Before importing the project into IDEA, I performed a "mvn install" from the parent directly.
