Can't run Plugin in Mac OS

Try running on Java 8 instead of Java 11.

I can't find any other plugin sdk there

IntelliJ IDEA Community Edition IC-183.5912.21

This is the current one

How to find the version 8 SDK?

Install JBR8 or Oracle Java 8, see https://intellij-support.jetbrains.com/hc/articles/206544879 for the https://bintray.com/jetbrains/intellij-jdk/ links.

Now That problem is fixed, But anyway my plugin is not starting. It shows some error in the plugin. But same code, in Windows it is working perfectly.

Please post full stacktrace from idea.log of test instance.

Rebuild the plug-in with Java 8 target level.

Hi Serge,

I didn't get the point. In the above comment, I put a screenshot of Project structure window. In that, I used IntelliJ IDEA Community Version (Java 1.8.0_201) with project level language  8- Lambdas, type annotations etc. 

Any other way to build? Please elaborate. 

I decompiled one class and It shows byte code version(52 java 8)

Or is there any issue with my mac's JRE? 

According to the error, the jar file of the plug-in you are loading in the IDE contains classes that were compiled with Java 11 target level.

It could be either the core classes of the plug-in or some library you are using in your dependencies. You need to rebuild all the classes with Java 8 target and try again.

Try to delete the sandbox directory in case it contains some old plug-in classes previously built with Java 11.

Ok Serge

Now the problem fixed.

What I did is, removed the production/ out folder and imported as a new project. Then overwrite the .idea folder. 

Thanks for your time.
