Description Martin Ahrer

2007-06-22 12:02:05 EDT

Build ID: I20070608-1718

Steps To Reproduce:
1. define a user library (e.g HIBERNATE including D:Projects/.m2/repository/commons-collections/commons-collections/2.1.1/commons-collections-2.1.1.jar)
2. define a user library (e.g. JSF including D:Projects/.m2/repository/commons-collections/commons-collections/2.1.1/commons-collections-2.1.1.jar)
3. add both user libraries to a project

this will get you a build path error

Build path contains duplicate entry: 'D:Projects/.m2/repository/commons-collections/commons-collections/2.1.1/commons-collections-2.1.1.jar' for project 'test'




More information:
This ist a very typical situtation when working with the JSF and the JPA facet: For example both JSF and JPA (Hibernate) work with commons-collections. So it's fairly impossible to create a web app using WTP facets JSF and JPA

Would it be better if this situation could be lowered to a warning (or ignore) ?
