  major.minor version 52.0

sounds like a java problem to me. something which occurs when you want to run a code which was compilated with a newer version of java of the one you use to run (like compilated with java 8 and running it with java 7)

@reedrichardsm

Hi Thanks for your reply do you know how to resolve that issue ? Actually I am using java 7

Well can’t unfortunately give you the right answer :frowning: Also I’m just guessing…but maybe some clues: How do you build your app? Which comman(s) did you run? Which JDK are installed on your computer? How is your JAVA_HOME defined?
