Hi Guillaume, The package looks good, thank you very much for packaging this library. The only issue I see is the prebuilt gradle wrapper in the source tarball. Even if it isn't used it should be removed. You can get a look at the libspring-java package [1] to see how this is done for other packages with a Gradle build.
