Bit thrown today - I checked out an old commit from 16 months ago. A docker

docker build . --no-cache

builds fine running

RUN ./gradlew --no-watch-fs --stacktrace build

The same command outside docker fails as so:

* What went wrong:

Now it's true that I do not provide versions for

com.fasterxml.jackson:jackson-bom

or

org.eclipse.jetty:jetty-bom

- the project is basically an enhancement of another dependency, which has versions for them, so I let it control those versions. How is it possible that the same gradle version can resolve those dependencies in Docker, but not locally? (I've tried disabling the build and configuration cache, same error.)

possibly missing a property or other configuration that sets those versions?

Not that I can see. Compared build scans, the only obvious difference is that in the scan from the docker build the dependency that defines those bom versions has them as dependencies, and in the scan from the local build it does not. But I don't understand why - I've even blown away my local

~/.gradle/caches

to force a redownload of that dependency, and of course in docker it gets downloaded every time. So the metadata should be the same - but clearly isn't.

interesting. are the repositories the same in each case? perhaps there’s mavenLocal() or some other repo difference?

That was it. I had a

mavenLocal()

repository. Removing it makes it pass. Great spot.

good stuff.

mavenLocal()

== janky behaviour.

Thanks very much, I thought I was going mad...
