Rework or remove agent configuration merging

[sdeleuze]

As shown in this branch with the samples/commandlinerunner-agent project, when executing mvn -Pnative -Dagent=true -DskipNativeTests clean test package the execution fails because native-image-configure generate --output-dir=/home/seb/workspace/spring-native/samples/commandlinerunner-agent/target/native/agent-output/test do not provide inputs.

Related code is in MergeAgentFiles and related to AGENT_SESSION_SUBDIR.

I am wondering if we could just avoid doing this kind of processing and just pass the generated configs to native-image since we can provide multiple ones.

Tested on Maven only but could impact Gradle as well.

@sdeleuze Can you retest this since #230 and #247 got merged?

[sdeleuze]

Happy to try, but is this supported on Maven (which our samples are using)?

[lazar-mitrovic]

Well we have https://github.com/graalvm/native-build-tools/blob/master/native-maven-plugin/src/main/java/org/graalvm/buildtools/maven/MergeAgentFilesMojo.java .

If it isn't working for this use-case I'd be happy to rework agent files merging in the near future.

Ok I will test it today and comment here with the outcome.

Works as expected, even if it would be nice to support the use case "run agent for test in order to compute main native config" with less verbose Maven configuration, see spring-attic/spring-native#1247 (comment).

Maybe we can close this issue for 0.9.12 and I will create a new one to polish the use case described above?
