Fail to run AOT process step on native build

[guillaume-1]

Hi,

I tried to build a native image from a Spring Boot 3.0.0 project (Webflux based on Netty, Mongo reactive)
I've already created an issue on springboot project, but the error seems to be generated by spring data class : org.springframework.data.util.TypeContributor
Here my compile stacktrace with "gradle nativeCompile" command:

Task :processAot

Can you help me please ?
Thanks.

Could you please share a minimal sample (something that we can unzip or git clone, build, and deploy) that reproduces the problem. That would help us spot the issue.

[guillaume-1]

Sure @christophstrobl
You can reproduce it running : ./gradlew build on this attached repo
skaly-native-test.zip
Note that I had to add implementation 'org.mongodb:mongo-java-driver:3.12.11' to avoid this at the same build step : java.lang.ClassNotFoundException: com.mongodb.client.MongoCollection
But this causes conflicts with spring data mongo dependencies at runtime.

thanks @guillaume-1 - will have a look!
