AOT Generated Spring Data Repositories clash in process-aot and process-test-aot

[mipo256]

Assume the application production code was build with the spring-boot:process-aot goal executed in Maven or equivalent task in Gradle. This production application code contains Spring Data AOT JPA repositories.

If later the tests for this application are compiled via mvn test-compile with the spring-boot:process-test-aot, then the exception occurs, likely due to the fact the Spring Data AOT Repositories were generated in process-aot step already and then process-test-aot tries to do the same.

To reproduce - if we would run basic mvn clear package with process-aot and process-test-aot as parts of the build as well for the Spring PetClinic with the 4.0.0-M1 as the parent (I'll open PR shortly in PetClinic for that), we would get the following error:

Caused by: java.lang.IllegalStateException: /home/user/OpenSource/spring-petclinic/target/spring-aot/test/sources/org/springframework/samples/petclinic/owner/OwnerRepositoryImpl__Aot.java already exists
	at org.springframework.aot.generate.GeneratedFiles$FileHandler.create(GeneratedFiles.java:279)
	at org.springframework.aot.generate.GeneratedFiles.lambda$addFile$1(GeneratedFiles.java:170)

It is not immediately clear how this issue should be even addressed. I'm sorry if this issue should not reside in the Spring Boot domain at all, just created it to keep track of this.

Actually, it seems that the problem is not even in the clash of process-aot and process-test-aot. It seems that the process-test-aot clashes with itself, because the same exception occurrs even if you disable the spring data aot repositories generation via -Dspring.aot.repositories.enabled=false, or even exclude the process-aot goal/task at all

Thanks for the report.

Testing is different than production code. AOT runs for each context and Spring Data doesn't account for that most probably as it doesn't seem to create an index in the name. I unfortunately can't move this to https://github.com/spring-projects/spring-data-commons so please create it over there with a link to this issue so that the team can see the history.
