Unsupported major.minor version 52.0 [duplicate]

Answer 1

I had Java 1.7 & 1.8 installed (with SBT 2.4 that requires Java 1.8). Even though my project was linked to Java 1.8, I had to change the JAVA_HOME environment variable to point 1.8. Finally, problem solved.

Answer 2

I solved my problem by removing old versions of JRE and installing JRE 8.

Answer 3

If your JDK version is right. Another reason that may cause this error is that your Android Studio is in a low version, but your Gradle version is too high. Upgrade your IDE to a newer version may help this.

Answer 4

You must run and compile your application with the same version of Java.

If you're using Eclipse you should do 2 things:

1. In Eclipse, click on "Window > Preferences", and in the window that appears, on the left side, under "Java", click on "Installed JREs", click on "Add..." and navigate to the folder that contains the JDK.

2. Right-click on your project and click on "Properties", in the window that appears, on the left side, click on "Java Compiler" and uncheck "Use compliance from execution environment on the Java Build Path", this allows you to choose in the the list "Compiler compilance level" the same version that you set in the previous step.

Answer 5

If you're using the NetBeans IDE, right click on the project and choose Properties and go to sources, and you can change the Source/Binary Format to a lower JDK version.

Answer 6

None of these answers helped me, but I found a solution.
I had a webproject used in Wildfly 8.2, built with Maven, source and target was set to 1.8 on maven-compiler-plugin, as well as all Eclipse and Maven settings were set to Java 1.8. The problem was that Wildfly 8.2 cannot handle Java 1.8, so I had to set everything to 1.7 and it worked.
