Error occurred during initialization of boot layer FindException: Module not found
I had the same issue and I fixed it this way:
Deleted all projects from eclipse, not from the computer.
Created a new project and as soon as you write the name of your project, you get another window, in which is written: “Create module-info.java”. I just clicked “don’t create”.
Created a package.
Created a Java class inside the package.
I run the file normally and it was working fine.
