Unrecognized option: --add-opens=jdk.compiler/com.sun.tools.javac.code=ALL-UNNAMED
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
I found other comment to check Lombok works and I see it is fine.
How to fix the problem?
ANSWER
Answered 2021-Jul-28 at 07:22You are running the project via Java 1.8 and add the --add-opens
option to the runner. However Java 1.8 does not support it.
So, the first option is to use Java 11 to run the project, as Java 11 can recognize this VM option.
Another solution is to find a place where --add-opens
is added and remove it.
Check Run configuration in IntelliJ IDEA (VM options field) and Maven/Gradle configuration files for argLine
(Maven) and jvmArgs
(Gradle)
