Implement source include/exclude source support

[dmikusa]

Describe the Enhancement

Implement include/exclude behavior.

Possible Solution

The Java buildpacks are implementing source include/exclude inline by calling code from the source removal buildpack. This means it needs to be added into the buildpack at the correct location. Like we did with the build tools buildpacks.

Motivation

In some cases, you want source files to be carried over into the final image.

This is a requirement also when using the Dynatrace GraalVM Native Image Maven Plugin.

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

It states the following in the document:

"Typically, the resulting Native Image will be available in the target folder. In addition to the Native Image, there will be a dynatrace folder. It is required for monitoring at runtime. If you want to run the Native Image on another machine, copy the dynatrace folder along with the Native Image."
