[Bug]: maven source artifact does not contain sources from shaded artifacts

[asbachb]

Module

Core

Testcontainers version

1.17.3

Using the latest Testcontainers version?

Yes

Host OS

not related

Host Arch

not related

Docker version

not related

What happened?

The testcontainer maven source artifacts (e.g. https://repo1.maven.org/maven2/org/testcontainers/testcontainers/1.17.3/testcontainers-1.17.3-sources.jar) does not contain sources for shaded artifacts.

So any classes which are put into: org.testcontainers.shaded are missing.

Relevant log output

### Additional Information

_No response_

[kiview]

TBH, I am not sure if there is something we can do about it.

[asbachb]

Seems to be unsupported by gradle shade plugin: GradleUp/shadow#41

[bsideup]

Hi @asbachb, shaded classes are "internal" and not supposed to be used by anyone. We also have a check that ensures that we never leak them to the public API. So it is "by design" in some sense.

[asbachb]

@bsideup sources are needed for debugging not for development. So from my understanding it does not matter if it's "internal" or not.

What's the point of publishing the sources if I cannot debug the "internals"?

[gsaviane-fs]

Specifically this bug #9542 cannot be debugged without having the shaded sources
