Can't pass necessary libraries to final native image

[FejKer]

Hello, I am strugging with attaching necessary runtime libraries for my graalvm native image.

I want my service to be observed by Dynatrace. For this to happen, I need to configure my pom.xml file, to

• download the agent during build time
• generate target/dynatrace directory
• read the dynatrace directory during runtime (it needs to be on the same level as the native image)

https://docs.dynatrace.com/docs/ingest-from/technology-support/application-software/java/graalvm-native-image#get-started

The problem is - I could easily get regular maven build to work, however using buildpacks with jammy full stack builder, I just don't know how.

Things I tried:

• using BP_INCLUDE_FILES flag with target/dynatrace and target/dynatrace/** values - it did not work, because there were neither directory nor any files present in final image next to the executable
• overriding the image with my dockerfile, that manually copies the prebuilt libraries next to the native image executable in /workspace, /cnb/process and /cnb/lifecycle - also did not work

So to sum it up - I need my final image to be shipped with either prebuilt or built during build time dynatrace libraries. They are not present in the final docker image and even if I manually put them in, they do not seem to work.

I can see that the Dynatrace stage is executed correctly during maven build.

Any ideas that could help me with that matter?

Best regards.

I suspect that this will solve the issue for you, but it's not implemented yet. paketo-buildpacks/native-image#280 You can follow that for progress updates & if you're interested in submitting a PR, to implement it, just let me know. Happy to point you in the right direction.
