Does Buck support Scala?

Looking through the source code, I noticed several references to scala_library(), and using it in my BUCK file seems to work (except it asks me to specify a Scala library dependency). However, there does not seem to be any reference to Scala at all on the documentation site. Does this library support Scala or am I missing something?

@kageiit Oh wow, my bad. I forgot to include the mvn: prefix this time around, but in my original code I had it in and still got an error. I added the prefix back to my URLs and updating the hashes to rule out hash errors I still get an error:

Unable to download: mvn:org.scala-lang:scala-library-all:pom:2.12.4
Build failed: Command failed with exit code -1.
    When running <curl>.
    When building rule //:scala-library-source.

And like before, here’s the v8 output.

It would appear it’s checking for the existence of http://central.maven.org/maven2/org/scala-lang/scala-library-all/2.12.4/scala-library-all-2.12.4-pom.jar, which doesn’t exist. However, http://central.maven.org/maven2/org/scala-lang/scala-library-all/2.12.4/scala-library-all-2.12.4.pom does exist, which Gradle still seems to be able to understand despite Buck failing to.

I actually just did a check and changed my task to:

remote_file(
    name = 'scala-library-source',
    out = 'scala-library-source.jar',
    url = 'mvn:org.scala-lang:scala-library:jar:2.12.4',
    sha1 = '7663f74ef944453c86cc7e6597ed33e9281f6412',
)

and it seems to work now… I’m not super familiar with how pom files are handled, so I guess I’ll just ignore it. Anyway, I’ll close this for now seeing it seems to be working and I’ll look into updating the docs.

@Nickersoft the remote file url seems incorrect

according to https://buckbuild.com/rule/remote_file.html , you need a mvn: prefix before your maven coordinates
