Eclipse - module not found when adding module-info.java

Gert Kommer picture Gert Kommer · Nov 27, 2017 · Viewed 26.2k times · Source

I have a simple hello world project in eclipse that I want to run with java 9. The program runs when I don't have a module-info.java file but when I add that file I get the following error:

Error occurred during initialization of boot layer
java.lang.module.FindException: Module modulefinder not found

Steps to reproduce
1. Create a new maven project
2. Change compiler and build path jre to 9
3. Auto generate module-info.java
4. Update junit dependency in junit to 4.12 if eclipse complains
5. Run the project

Is this an eclipse related issue or am I missing something when running the project?

FYI eclipse version I use is Oxygen.1a Release (4.7.1a)

Found the answer based on intellij output:) I had to add the location of the classes to the vm arguments in the run configurations as well as the module name/path to main. like below. See the java -help command for more info regarding -m and -p
