Remote Container build does not copy all build artifacts

[hijoft]

We are building a Quarkus native image in Gitlab Pipeline using Gradle and "remote container build" with Docker.
Since we added https://quarkus.io/extensions/io.quarkiverse.poi/quarkus-poi/ extension and configured the Dockerfile according to Quarkus-POI guidelines (install and copy libraries), we faced java.awt.Font NoClassDefFoundError errors during generation of an Excel sheet.

ERROR [io.qua.ver.htt.run.QuarkusErrorHandler] (executor-thread-7) HTTP Request to /reports/api/v1/download?start=2023-01&end=2024-12&source=ALL failed, error id: 6dc1b7cd-0365-4e01-b08c-b18f861228d9-1: java.lang.NoClassDefFoundError: Could not initialize class java.awt.Font

Debugging has shown the *.so files generated next to the *-runner application files are not copied back to the build output directory from the remote container. Building it locally by using just "container build" works as expected and the runtime error did not appear with the required *.so files next to the *-runner application file.

Debugging the build process confirmed: only the *-runner file is copied back from the container.

Digging into the source we found there is no option to preserve the other produced build artifacts, just the executable will be copied back.

Line 57 in 20d3c9d

protected void postBuild(Path outputDir, String nativeImageName, String resultingExecutableName) {

It would be great to have all build artifacts preserved for further steps in the build process.
For now we just copy the libs from a different location, but it would be great to just use them from remote container build.

It requires a similar fix to this one, i.e. to copy the libs. Note that it is paramount to those libs coming from the same build as the main executable.

@Karm do you plan on working on that?

[Karm]

@geoand My Gradle-fu is weak, but I'll try 👍

[Karm]

I have the issue reproduced, fixing shortly...
