Spring TestAotProcessorTests failure on MS Windows

Hi, I'm following the "build from source" guide, but there's one failed test: TestAotProcessorTests

After I clone from the repo and type ./gradlew build command, this test fails as follows.

java.lang.AssertionError:

This is the only failing test, and I tried to build multiple times.

Please let me know if you need additional information. Thanks.

Can you please confirm that you are using Microsoft Windows?

Comment From: snicoll

We've had the same problem in Spring Boot with our Windows build. Using Path.of makes sure that the path can be resolved on all OSes, see https://github.com/spring-projects/spring-boot/blob/0f9ff867e7558ce204d76d2e86e6a1704a97c23c/spring-boot-project/spring-boot-tools/spring-boot-maven-plugin/src/intTest/java/org/springframework/boot/maven/AotTests.java#L43

Comment From: sbrannen

This has been fixed on the main branch and should now work on MS Windows.

If it does not, please let us know.

Thanks for creating your first issue for the Spring Framework! 👍

Thanks for providing the link, @snicoll.

I wasn't aware of Path#subPath. Combining that with Files.walk (instead of Files.find like I was previously using) helps to greatly simplify my findFiles implementation:

@xieruiyuan, I have pushed a change to main that relies solely on Path APIs as suggested by @snicoll.

Please let us know if the build still works for you on Windows.

Thanks
