Is the gradlew file present in your Nukkit directory, and has the file executable permission? (if it doesn't you can give them using chmod +x gradlew)

I tried to build the docker image using the same command you used and I cannot reproduce the issue

I confirmed the gradlew file permission in my Nukkit directory

-rwxr-xr-x 1 root root 8739 Oct 24 18:06 gradlew

No ploblem

[Iyarr]

I executed the command by hands from Dockerfile , and it occured this error on execution at ./gradlew shadowJar

bash: ./gradlew: /bin/sh^M: bad interpreter: No such file or directory

I think it occured error by newline character on windows PC
