I am working with SWTBot, and created a plugin in order to test my application's GUI. At the point i have been able to initiate the bot, but i am not getting the following exception when testing the product:
java.lang.NoClassDefFoundError: edu/emory/mathcs/backport/java/util/concurrent/BlockingQueue

It happens when the program tries to build a session factory in Hibernate. I've been googling a lot and most of the answers i found are related with maven/spring usage, which is not what i am using.
The problem seems to be the lack of backport.util.concurrent.jar, which is (or should be) included in the java.util.concurrent.jar.
I managed to create a plugin from the backport.util.concurrent.jar and include it in my target-definitions, but the problem still persists.
Does anyone have a clue of how this problem can be solved? Any help will be much appreciated.
Thanks in advance!
I figured it out. I thought the problem was in my swtbot tester plugin, but it was indeed in one of the several plugins present in the product i am testing. Solution was to add the dependency in the correct plugin of the product (instead of adding it in the swtbot tester plugin).
Thanks anyway
