[FIXED] Cannot load logging resource file in spring boot with java 11

Issue

I have a problem migrating my application to java 11. I recieve a FileNotFoundException when trying to load my logging config.

java.io.FileNotFoundException: class path resource [logging/logback-local.xml] cannot be resolved to URL because it does not exist

This is done via configuration and worked in Java 8:

This is my application.yml

logging:
  config: classpath:logging/logback-local.xml

application structure looks like this:

src
  -main
    -java
      -foo.bar.Application.java
    -resources
      -application.yml
      -logging
        -logback-local.xml
pom.xml

pom:

I think this is a problem with the jigsaw modular system, but I could not find any solutions to this on the Internet.

Thanks for the help!

Solution

So after some fiddling around, using the suggestion from Hatice, the problem disappeared. I have no idea what caused the problem.
