Provide a user-facing API to deal with GraalVM options

[gsmet]

For extension developers, we have all the BuildItem machinery which takes care of configuring GraalVM.

For applications themselves, we expose @RegisterForReflection but that's pretty much it. There's a need for a user-facing API allowing to configure GraalVM from the application code itself (add resources, resource bundles...).

Maybe some of this should be driven by config, e.g. file globs for matching resources to keep in the final image.

Also it would be nice to align some of this between JVM mode and native image, for example if I want to have some resource available at run time, I should be able to just specify that I want that resource instead of having extra config for native image. Non-included resources should be excluded from both JVM mode and native image.

The closer we make the experience between the two, the easier it will be for users to move from JVM to native image in their dev cycle.

See https://stackoverflow.com/questions/55300484/how-to-include-classpath-resources-in-a-quarkus-native-image/55300914#55300914 for a user asking about that.

Seems to be coming up a lot lately :)

As a Maven user, I would expect all my Maven resources from the current reactor to be included in the final image (otherwise, I wouldn't put them in the reactor in the first place), and of course I wouldn't want to worry about any patterns to match exactly my resources and nothing else from the classpath, so it would be really nice if quarkus-maven-plugin could do the job for me.

Resources are addressed more specifically in #2746.

hello,

I have try to list all option, that I found in release note of graal:
seems missing:

• FlightRecorder
• StartFlightRecording
• FlightRecorderOptions
• FlightRecorderLogging
• DefaultLocale
• IncludeLocales
• IncludeAllLocales
• DeleteLocalSymbols
• ActiveProcessorCount
• StaticExecutableWithDynamicLibC : build native image staticly except libC (docker optimization)

Seems not needed:

• InlineBeforeAnalysis : InlineBeforeAnalysis enabled by default in coming GraalVM 21.3 release #19446, not needed
• RemoveSaturatedTypeFlows Add job to test -H:+RemoveSaturatedTypeFlows and -H:+PrintAnalysisStatistics #9794
• SerializationConfigurationResources : handled with reflection class build item Serialization feature support #15380
• AllowVMInspection (seems implemented but not documented) and needed for flightRecoder
• EnableSecurityServicesFeature: not needed. just to disable optim of remove uneeded security providers
• SubstitutionResources : to be able to declase substitution class. objectSubstitution and class substitution is done with annotation so ok
• ReflectionConfigurationResources : handled with builditem
• ReflectionConfigurationFile : handled with builditem
• ResourceConfigurationFiles : handled with builditem
• JNIConfigurationResources : handled with builditem
• ResourceConfigurationResources : handled with builditem
• DynamicProxyConfigurationResources : handle with NativeImageProxyDefinitionBuildItem
