When run -Pagent the reflection-config.json include Test classes about native-build-tools

[ScottPierce]

Does it matter if it includes reflection information for classes that are not actually compiled into the application?

Yeah, native image generation fails because in the classpath those classes are not present. So you have to add the

-H:+AllowIncompleteClasspath

You can use
gradle -Pagent run
if you want to generate agent output for main source set.

Filtering of classes which are detected during an agent run is done using agent-filter files. Advanced configuration of native-image-agent isn't (at the moment) exposed to the end-user through our plugins (you could work around that by changing JVM parameters when invoking relevant tasks of said build tools).

agent-filter.json which is present in the Gradle plugin is only used for filtering out internal Gradle classes (which are detected if run task is invoked in the same JVM as the Gradle process itself).

Also note that if you set agent=true in your configuration, --allow-incomplete-classpath will automatically be added to the native-image invocation.
