Getting BSP running thread

Question

ancient-vegetable-10556 · Answer

Currently importing into intelliJ gives me this error ```request failed buildTarget scalacOptions bsp error ValueError File with digest Digest hash Fingerprint lt 08f983b45ef2306eaca35e9280aae2b8691a063e1f2d04b0f5d38f910cda7c19 gt size bytes 134857 not found 32602 ``` that hash corresponds to `com google errorprone error prone annotations 2 7 1`

ancient-vegetable-10556 · Answer

It starts working if you run ` pants check ` before doing a BSP import though Is this intended behaviour or do we want a BSP import to work cleanly before running pants < witty crayon 22786> < fast nail 55400>

witty-crayon-22786 · Answer

mm no that s a bug that i noticed and then forgot about the code is currently directly taking digests from the lockfile and assuming they already exist on disk

witty-crayon-22786 · Answer

i ll file it

< witty crayon 22786> I m reaching a bit of an impasse here I can definitely get IntelliJ to pick up a hardcoded JDK path The problem is that creating that JDK path requires us running `cs java home` under a sandbox which appears to put everything under hardlinks I could potentially use the runtime JDK stuff that I put in place for running deploy JARs and materialise the JDK into ` pants d bsp` but that still seems a bit icky Thoughts

ancient-vegetable-10556 · Answer

happy to jump on a call to talk it through too this probably needs more pickling of internals than I expected

witty-crayon-22786 · Answer

gt which appears to put everything under hardlinks that should be fine it should be a location under `~ cache pants named caches`

ancient-vegetable-10556 · Answer

Yes that s correct

ancient-vegetable-10556 · Answer

the trick is that the suffix is loooooooooooong

witty-crayon-22786 · Answer

such that it causes a failure

ancient-vegetable-10556 · Answer

No failures yet it s more about trying to actually get a directory name that I can give to intelliJ and expect it to stick around

witty-crayon-22786 · Answer

imo inside of the cache is fine

ancient-vegetable-10556 · Answer

I know that

ancient-vegetable-10556 · Answer

the problem is actually finding the directory in the cache

witty-crayon-22786 · Answer

is the issue that `cs java home` is giving you the location within the sandbox to resolve that you d need to use the bash equivalent of `realpath` to have it resolve through the symlink

ancient-vegetable-10556 · Answer

I definitely expect the jdk to stick around the issue that coursier unpacks it unto a directory that is hardlinked inside the sandbox

witty-crayon-22786 · Answer

symlinked

ancient-vegetable-10556 · Answer

mac os seems to think it s a hardlink can I dereference that

witty-crayon-22786 · Answer

a parent directory is a symlink

witty-crayon-22786 · Answer

inside of the sandbox there will be a ` cache coursier` directory and that will be the symlink

witty-crayon-22786 · Answer

but i think that a canonical path realpath call on the full path will still expand that

witty-crayon-22786 · Answer

the JDK isn t an immutable input

witty-crayon-22786 · Answer

it s in the named caches

ancient-vegetable-10556 · Answer

One moment

witty-crayon-22786 · Answer

ancient-vegetable-10556 · Answer

I am working from that one moment

witty-crayon-22786 · Answer

something like `realpath $ cs java home ` should do it

ancient-vegetable-10556 · Answer

OK I can run `realpath` from the jdk preparation script and that gives me the cache I d been using readlink which I think needs you to find the specific directory rather than going up the tree itself

witty-crayon-22786 · Answer

yea

witty-crayon-22786 · Answer

that s right about readlink

ancient-vegetable-10556 · Answer

realpath looks like it comes from homebrew so I think I ll have to traverse that tree myself

ancient-vegetable-10556 · Answer

sigh

witty-crayon-22786 · Answer

hm

witty-crayon-22786 · Answer

oh hm yea that s annoying

ancient-vegetable-10556 · Answer

Actually I should be able to do that in python just by finding the common suffix

witty-crayon-22786 · Answer

um maybe do it from Python

witty-crayon-22786 · Answer

oh crap not quite the sandbox will already be cleaned up

witty-crayon-22786 · Answer

but if you write the script as a python script using `PythonBinary` you can run python in the sandbox

ancient-vegetable-10556 · Answer

right
