Clojurians Log v2
clj-on-windows
I'm getting this error during compilation (compile-clj) and it only happens when I depend on maven dependency that has lots of transitive dependencies. I thought it could be the long classpath issue so I tried adjusting my maven-local to something shorter on a different drive (D). However it is still looking for some main class on my C drive:
Error: Could not find or load main class Dumais\AppData\Local\Temp\compile-clj15644282254864761747\compile-clj;target.classes;src;C:\Users\Paul

Clojure compilation failed, working dir preserved: C:\Users\Paul Dumais\AppData\Local\Temp\compile-clj15644282254864761747 It seems to have an issue with the space in my home directory name.
I've heard about this issue recently in #tools-deps or #tools-build as well. Maybe it helps looking in there as well
haha, was that me?
oh that was probably you :)
what answer did you get there then?
Nothing yet, but then I went down a different path and back again - so I got help on the second issue.
At first I was going to launch clojure code via java in an existing app, but then thought a separate app that uses the java app as a dependency would be easier.
Hence I'm back to trying to make an uberjar using tools.build.
Have you tried :use-cp-file?
I'm suspecting it's a Windows specific escaping issue with how tools.build calls process builder (which I've accounted for in babashka.process when I ran into that) but I'm not sure. :use-cp-file may help
it could also be useful to get a hold of this file: https://github.com/clojure/tools.build/blob/f096376cd4e301dbf90ce447fee901397d3490c0/src/main/clojure/clojure/tools/build/tasks/compile_clj.clj#L105 and see what's in it
I find it interesting that running clj -P is now downloading a bunch of dependencies that it didn't do before trying to compile.
Haven't tried :use-cp-file
Do I change this to :always or :never?
Tried always but that didn't work. Trying never...
I think true?
I'm using clojure via scoop and bash.
ah yes :always
try that
hmmm, now I get:
Execution error (FileNotFoundException) at java.io.FileInputStream/open0 (FileInputStream.java:-2).
C:\Users\Paul Dumais\AppData\Local\Temp\uber10211030562887780850\LICENSE (Access is denied)This has come up before in #tools-build: sometimes a dependency has a LICENSE directory but another has a LICENSE file
you can add a conflict handler for that
ahhh, yeah seen that too somewhere...
but this is a good sign, it's getting further now
Hmm, tried putting in this as an option to compile-clj but no joy so far:
:exclude [#"(?i)^META-INF/LICENSE/.*"
#"^LICENSE/.*"]what about just ".LICENSE."`
fucking markup
I had the options in the wrong part - trying it in b/uber
Ok, added #".LICENSE." , but that didn't work either.
i meant .*LICENSE.*
but the markup fucked it up
ah
That did it!
Thanks!
You may want to report your first issue before :use-cp-file in #tools-build though, I think I know the root cause but it's better if it got solved properly. I think clojure.java.process in 1.12 will suffer from the same issue actually
A repro that people can readily clone and run will help
Also specify Java version / vendor
But maybe that's not the root of the issue - not sure.
