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.
