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?
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.22.0</version>
<configuration>
<parallel>methods</parallel>
<useUnlimitedThreads>true</useUnlimitedThreads>
</configuration>
</plugin>In bazel the parallelism unit is targets.
In any case you’re welcome to open an issue to suggest more fine grain parallelism and we can discuss it further
@ittaiz @johnynek I have one more question, in order for the targets to be executed in parallel, do I need to have a main build file which calls them?
filegroup(
name = "build_all",
srcs = [
"//services/service1:build",
"//services/service2:build",
"//services/service3:build",
]
)Will doing it like this make the execution sequential instead of parallel?
Btw. Don’t know the stage you’re in but if you’re in an initial I recommend you take a look at exodus which is a project aimed at migrating maven projects to fine grain bazel targets. We (Wix) used it to migrate ~10MLOC
Amazing! Well, most of the things have been migrated, however, there are still some that haven't been, so this will come handy, I started looking into it yesterday :)
Hello, I'm getting a bit weird error when defining custom dependencies with scala_proto. I've followed the docs at https://github.com/bazelbuild/rules_scala/blob/master/docs/scala_proto_library.md I've added the scalapb_toolchain and default_deps_toolchain but I'm getting error
File "/private/var/tmp/_bazel_hrvolap/cbad7e6dac15bf07632f0b5b890ca227/external/io_bazel_rules_scala/scala/private/toolchain_deps/toolchain_deps.bzl", line 13, column 9, in _lookup_provider_by_id
fail(_required_deps_id_message(ctx.attr.name, toolchain_type_label, deps_id))
Error in fail: scalapb_worker_deps requires mapping of scalapb_worker_deps provider id on the toolchain @io_bazel_rules_scala//scala_proto:deps_toolchain_typewhich seems like needs to be added to toolchain, but when I added it as a dep_provider to the default_deps_toolchain I get dependency cycle.
Also the whole story why I want custom dependencies because grpc client dependency is overlapping with dependencies for bigtable and version are not compatible
SOLVED
I've redefined in my workspace
declare_deps_provider(
name = "scalapb_worker_deps_provider",
deps_id = "scalapb_worker_deps",
visibility = ["//visibility:public"],
deps = [
"@com_google_protobuf//:protobuf_java",
"//third_party/jvm/com/thesamet/scalapb:protoc_bridge",
"//third_party/jvm/com/thesamet/scalapb:compilerplugin",
],
)and included it in default_deps_toolchain, then everything worked
