I'm working with Spring Boot, GraphQL, and gRPC in my project. I’ve been testing the app by running it, and it has been working fine. However, when I tried to build it using mvn package to generate gRPC classes, it give me a bunch of errors as follows:

Results :
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0(I had to cut some of the errors because of the character limit)
As you can see, it still says Failures : 0 and the build is success in the end. However, the classes I need for gRPC are not generated. I'm using graphql-java-tools for GraphQL.
Any idea how to solve this problem? Any help is appreciated, thanks!
