[Eclipse Jaspersoft Studio 6.0.4 total fail on Linux install and Windows install]

I fixed this problem myself. Reading the stacktrace I found that there was a dependency in my pom (I'm using Maven) to a library org.slf4j:jcl-over-slf4j. Excluding this the problem is solved. It would be nice if this kind of problems was handled nicer and maybe documented in some requirements document.

 

 

[Eclipse Jaspersoft Studio 6.0.4 total fail on Linux install and Windows install]

I have installed the plugin for Eclipse and I want to create a Jasperreport and fail drasticly at once. This happends on Windows 7 and Linux Ubuntu 14.10. Please let me know what information is needed. I'm able to create a jrxml file, but when I try to open it in Eclipse there is always a crash with stacktrace given below. I'm not able to use the plugin, please let me know what is wrong.
