Problem/Bug New computer/ New bugs / Java compiler

Hello,
Recently I got a new apple air computer which is awesome, But I soon realized it would trouble me on eclipse. To get to the main point I keep on running into the unsupported major.minor version 52.0 error. I have tried multiple of times to change my compiler to 1.7 and I have even changed my execution environment to run Java 1.7 JRE. The problem still concedes. I am asking for help on how to solve this problem because without my eclipse working I wont be able to code a plugin that I need to be coded by a certain date.

Thanks for all the help,
camman00

given that by that stack trace, the server is running only java 7, focus on that and not the other compiler levels. You are likely missing one of the points to change in the project.

Also note you need the jdk as part of the solution here, not just the jre setting.

And note if you are using something like a maven project, the maven parts may be established for using java 8 settings and need as well to be adjusted

@Boomer
Thanks for the reply but the error still concedes

Heres a list of stuff that I have done so far.
* Compiler set to 1.7
* Eclipse runs JDK 1.7
* Execution environment matches 1.7 to 1.7 jdk
* Preferences page matches the properties page
