@hannu.hartikainen Holy cow, I absolutely loved your article on Google Jib as a way to run Java/Clojure apps in production. I’ve gotten Google Cloud Build container build times down to 45 seconds, using just distroless and the uberjar file. https://www.vincit.fi/en/clojure-in-google-cloud-run-with-jib/ I used the jib CLI, and was amazed that incremental uploads can take less than 7 seconds. I tried last night to use the Google Jib Core API to upload images, using the fantastic work in @vvehvilainen’s lein-jib-build plugin, but couldn’t get credentials loaded, after a couple hours of trying. This morning, I confirmed that the Jib CLI works, so I know it can be done. Any chance anyone might want to collaborate to get a simple tools.build interface to Jib running? (I’ll post a gist of my attempts from last night shortly.) Thanks, all! https://github.com/vehvis/lein-jib-build

Here’s the code I’m evaluating: https://gist.github.com/realgenekim/fdcad45286d065cc559cd75a8f946ad4#file-jib-build-clj-L45 And the error I’m getting is below. Any ideas?

Holy cow. I’m now getting credentials! Null Pointer Exception went away, when I passed in a real logger as an argument to CredentialRetrieverFactory. (Copied from JUXT Pack: https://github.com/juxt/pack.alpha/blob/master/src/mach/pack/alpha/jib.clj)
