For the simple Maven pom.xml config above, I'm using the spring-boot-maven-plugin to build my OCI image. Now, I want to include some extra folders/files under my project directory, and for the experiments I tried, BP_INCLUDE_FILES doesn't seems to have any effect (the image is successfully built)

1. my-stuff is a directory under my project root directory (where pom.xml is located as well) - nowhere to find my-stuff inside the OCI image built
2. my-stuff is a directory under src/main/resources - I tried both <BP_INCLUDE_FILES>my-stuff/*</BP_INCLUDE_FILES> and <BP_INCLUDE_FILES>src/main/resources/my-stuff/*</BP_INCLUDE_FILES> with no avail.

Using the command docker run --rm -it --entrypoint /bin/bash my-app-image:0.0.1-SNAPSHOT to examine the content of the built image:

it does seem that the builder "explode" the JAR into the BOOT-INF/classes folder (that's why there is no my-app.jar file) - but, how does BP_INCLUDE_FILES work? Please help!

Off the top of my head, what you're trying looks OK. Nothing is jumping out.

My first suggestion would be to try the same thing but using pack cli.

https://buildpacks.io/docs/for-platform-operators/how-to/integrate-ci/pack/

This will help to rule out issues with the plugin or Maven.

If you could also run your build, capture the output and post the full output that will help understanding what is happening.

Thanks
