I'm on Pants 1.27 trying to compile scala 2.12.8. I see here that 2.12.8 is also the default internal version, I was getting errors with 2.12.<latest> so I decided to stick with .8. However I see 2.12.14 getting pulled in 🧵

./pants depmap :myapp | grep 2.12.14

returns nothing, but

Copy code

./pants export :myapp | grep 2.12.14

            "default": "/Users/mitesh/.ivy2/pants/https/maven-central.storage-download.googleapis.com/maven2/org/scala-lang/scala-library/2.12.14/scala-library-2.12.14.jar"

@happy-kitchen-89482 any ideas to debug this? we've got

scala-library

in our managed deps. I tried to define

scala-library-synthetic

but it wouldnt let me.

Does this recur if you

clean-all

and delete any caches? in ~/.cache/pants ?

Yep ive nuked

.pants.d

and

~/.cache

, and bumped

cache_key_gen_version

to be safe

managed_dependencies

and

i dont see that 14 hardcoded in pants repo

Copy code

mitesh@pants $> git branch
* 1.27.x
  main
mitesh@pants $> > git grep "2\.12\.14"
mitesh@pants $> > git grep "2\.12\.8"
build-support/native-image/build-zinc-native-image.bash:  version='2.12.8'

Another clue, I printed out this line

jar_lib

and

jar_entry

and got this. Note the 2.12.8 vs 2.12.14 mismatch

Copy code
