Hi all,
I'm trying to compile some scala code that uses ScalaTest, but I'm seeing errors like the following:
error: exception during macro expansion:

at scala.tools.nsc.typechecker.Macros$class.macroExpandWithRuntime(Macros.scala:763)My dependencies.yml contains this:
org.scalatest:
scalatest_2.12:
version: "3.0.5"
lang: scala/unmangled
org.scalactic:
scalactic_2.12:
lang: scala/unmangled(I'm using bazel_deps.)
and in the BUILD file I have
scala_import(
name = "scalatest",
jars = [
"//3rdparty/jvm/org/scalatest:scalatest_2_12",
"//3rdparty/jvm/org/scalactic:scalactic_2_12",
],
)and my project (defined in the same BUILD file) then lists :scalatest as a dep.
(Based on some Googling, I've tried to supply --nouse_ijars, but that doesn't seem to have any effect. I suppose that's perhaps just for macros defined inside the repo itself and no external macros?)
Oh, yes, and I've also tried with regular 'scala' dependencies rather than scala/unmangled, but I'm guessting that that shouldn't really matter.

Hi,
Next week I'm merging a huge PR which effectively rewrites rule.
It has ben under review for 2 months and we've ran it through severa very large codebases (Wix's ~10MLOC passes with it) but I'd still suggest other companies to take it out for a spin and report on the PR bazelbuild/rules_scala#865.
On a related note I'll say that I'm not really looking here and I've moved to bazelbuild slack's org (#scala) so you're invited there as well.
Happy holidays
scala_library) currently doesn't add transitive dependencies to compile classpath? (the way java rules does with --strict_java_deps=off) indicated here: bazelbuild/rules_scala#235Any workaround to this, or do I simply need to add all actual deps (as part of migrating off maven)?
You’re right that rules_scala by default adds only direct dependencies but it has a strictdeps mode of warm and error which you can probably use for your needs. This is how we started out though we had a few other tools we’ve built like exodus (available on github)
Hey folks - trying to use bazel for a demo project (on my personal dev machine not behind some corporate firewall). this is the error i get ERROR: /home/ptandel/.cache/bazel/_bazel_ptandel/1dcc102f10d8db6f292e788f608253ba/external/io_bazel_rules_scala/scala/scala.bzl:561:5: //external:io_bazel_rules_scala/dependency/scala/scala_reflect depends on @io_bazel_rules_scala_scala_reflect//:io_bazel_rules_scala_scala_reflect in repository @io_bazel_rules_scala_scala_reflect which failed to fetch. no such package '@io_bazel_rules_scala_scala_reflect//': java.io.IOException: Error downloading [http://central.maven.org/maven2/org/scala-lang/scala-reflect/2.11.12/scala-reflect-2.11.12.jar] to /home/ptandel/.cache/bazel/_bazel_ptandel/1dcc102f10d8db6f292e788f608253ba/external/io_bazel_rules_scala_scala_reflect/scala-reflect-2.11.12.jar: Unknown host: central.maven.org
IIRC central.maven.org doesn't seem to be valid but i couldn't figure out how to specify something else (short of using a HTTP(S) proxy which I'm not sure would solve my problem)?
Hi. I am using IntelliJ, Scala, and the Bazel plugin. I am noticing that some dependencies are not resolved, leading to red font in the code window. The project builds fine from the command line however.
In particular, I've noticed that the .ijwb/.idea/libraries/ directory is missing an entry for com_typesafe_config_2_12_foo.xml.
com.typesafe.config dependency. It doesn't make sense to me because it's explicitly depended upon in my BUILD file (e.g. deps = [ "//3rdparty/jvm/com/typesafe:config" ]).
Hello!
Sorry about newbie question.
Where I can find sha256 for selecting scala version in WORKSPACE file?
https://github.com/bazelbuild/rules_scala#selecting-scala-version
There is a rules_scala governance doc in a world commentable google doc.
It is very much baked (and is based on previous work mostly done by the amazing @Oscar) and the main motivation of opening it up again is to see if I haven’t missed anything.
Re the main heated discussion of correctness and such- I’ve massaged the terminology based on suggestions here to be the most open while keeping the values I think are core.
In ~2 weeks I plan to send and merge a PR with this doc.
scala_proto_library call uses a custom toolchain? The docs just say "To configure ScalaPB options, configure a different scala_proto_toolchain and declare it in a BUILD file". Any build file? Every build file that needs it?
