I can reproduce the issue. This comes from here:

quarkus/devtools/cli/src/main/java/io/quarkus/cli/build/GradleRunner.java

Line 238 in 8033e5e

File buildFile = projectRoot.resolve("build.gradle").toFile();

I have fixed it. I'm adding a test.

Thanks @glefloch, we need to backport it to 2.0 and 2.1 if possible
