Unsupported major.minor version 52.0 [duplicate]

Answer 1

If you are using IntelliJ IDEA, go to Project Structure (Ctrl + Alt + Shift + S), and you can change your project's JDK.

Answer 2

Just want to add this. I had this problem today. Adjusted the settings in my project, rebuilt, and same problem. I had (incorrectly) assumed that changing the settings in my project (Eclipse) would cause the projects on which my project depends to be recompiled also. Adjusting the settings to all of the projects up the dependency tree solved the problem.

Answer 3

You will need to change your compiler compliance level back to 1.7 in your IDE.

This can be done in the preferences settings of your IDE. For example, in Eclipse go to menu Windows → Preferences, select Java, and expand it. Then select Compiler and change the compliance level to 1.7. I am sure this will work from there.

Answer 4

If you are using Eclipse, make sure your menu Project → Properties → Java build path → libraries → JRE system library matches your project requirements (as shown in the image).

Answer 5

If you have a problem in Android Studio and you have installed Android N, change the Android rendering version with an older one and the problem will disappear.

Answer 6

I had the same problem... a JDK and plug-in version conflict.

I compiled using 1.8 ... the latest one, and that message started to appear. So I've searched for the JRE 7 (http://www.oracle.com/technetwork/java/javase/downloads/server-jre7-downloads-1931105.html)... and installed it... again... Now 1.8 and 1.7 in the same computer.

Using NetBeans, and compiling, and targeting to version 1.7, fixed my problem.
