I’ve finally managed to strip out all my transitive

api platform("com.fasterxml.jackson:jackson-bom:2.18.0")

dependencies across all my libraries and to my surprise that’s made the warnings go away. Still curious if anybody knows what the problem actually was here though? Is declaring a BOM as an

api

dependency such a bad offence that it’s expected gradle would behave unpredictably?

Not per-se. No idea what caused that issue for you, maybe some nuanced edge-case, no idea. Maybe you should report a bug about it. 🤷‍♂️

Thanks @Vampire! I’ll raise an issue.
