seeing some strange behavior with lein trampoline. It seems that it downloads 3 versions of nrepl and then fails

[dan@fedora queue]$ rm -rf ~/.m2/repository/nrepl/
[dan@fedora queue]$ lein --version
Leiningen 2.9.1 on Java 1.8.0_232 OpenJDK 64-Bit Server VM

oh i read that too quickly. it gets 4 nrepl poms and a single nrepl jar

I have some tests failing in a docker container running in CircleCI. It fails with "Tests failed." and nothing else except the logs from my code. I don't get any test summary or anything. My tests are working locally and also work when I run "lein test" after sshing into the circleci container. Any idea why I don't have a test summary? There is nothing that indicates failure in my logs. I just get "Tests failed." with "Exited with code 1"

Looks like it was running out of memory

-Xmx768m fixed it right up

what code/lib does lein check actually run? is it cljfmt?

no

there different things

@drewverlee it’s basically running a clojure.core/compile on all clj ns’s in the configured source and (maybe) resource paths I believe.

whats the end result? to see if your code compiles?

Yes. That’s the main use I know of for it

Can see things like reflection warnings too if that matters to you

But without lein check you may not even attempt to compile all your ns’s - eg if not rests for some file or something & you are not doing AOT

I believe lein check enables something like (set! *warn-on-reflection* true) even for namespaces that do not contain that expression.
