Compiling modified graylog project

Hi all,

I have modified the master branch code for graylog and I want to create a docker image out of it.

i have used mvn -Dmaven.javadoc.skip=true -DskipTests package to create the jar files and tried to copy the stracture of these files as best as I can from the structure of graylog 5.0 package.
i have created the image using this repo:

slightly modified it so it wouldn’t take the package from the graylog site but us my own package.

once the image starts, after opensearch boots up I am getting this errer:
Exception in thread “main”

java.lang.NoClassDefFoundError: com/github/rvesse/airline/Cli

at org.graylog2.bootstrap.Main.main(

Caused by: java.lang.ClassNotFoundException: com.github.rvesse.airline.Cli

at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(Unknown Source)

at java.base/java.lang.ClassLoader.loadClass(Unknown Source)

... 1 more

which makes me think there was something wrong with the package command/ the way I took the jar files?

it works great when building the develop image or running locally from the IDE
