Hi, I'm using IAM (http://www.eclipse.org/iam), WTP and the GWT Google Plugin for Eclipse for a multi-module project (using flat structure): . |-- core | `-- pom.xml |-- gwt | `-- pom.xml `-- parent `-- pom.xml
When I run my application using the Web App launch, my "gwt" project is only using classes from the installed "core.jar" (from m2 repo) instead of using classes from the open project "core". The classpath used to run my application via the Web App launch is not configured as the classpath used by WTP when I'm running my application on server (in this case it uses the open project instead of the jar installed in my m2 repository). IAM and Google plugin were working fine with a single module project, but not anymore with multi-modules :-( Thanks for your help!
