Error occurred during initialization of boot layer FindException: Module not found

Question

Executing a simple \"Hello World\" program using Java 9 results in the following error message:

Error occurred during initialization of boot layer

Answer 1

I had the same issue and I fixed it this way:

1. Deleted all projects from eclipse, not from the computer.
2. 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".
3. Created a package. Let us call the package mywork.
4. Created a Java class inside the package myWork. Let us call the class HelloWorld.
5. I run the file normally and it was working fine.

Note: First, make sure that Java is running properly using the CMD command in that way you will understand the problem is on eclipse and not on JDK.

Answer 2

You say that your module-info.java contains

module myModule {}

That means it declares a module called myModule, not com.pantech.myModule. Pointing this from the command format:

 -m <module-name>/<main-class>
