charles Lgn :
I use IntelliJ 2018.3 and I need to use JDK 11.
The project compile on Eclipse (the Eclipse compiler) but not on IDEA (the Javac compiler)
So I decide to use Eclipse compiler on IDEA (Eclipse compiler 4.7.2) but I have always this error : 
Is there any solution to compile my programm on IntelliJ with the Eclipse compiler and if yes, How can I do that ?
CrazyCoder :
Use JDK 9 or lower, it's not supported for Java 10 and 11 yet: https://youtrack.jetbrains.com/issue/IDEA-190791 (Eclipse compiler specific limitation).
You can increase the heap size of the JVM running the build process and switch back to javac compiler instead of using Eclipse compiler:
This should fix the first error.
