Protosb descriptor isn't 2.x compatible about scalapb HOT 14 CLOSED

I use scalapb 0.4.14 and "com.github.os72" % "protoc-jar" % "2.x.5" using "-v261". It seems to work without problems having

syntax = "proto2";
import "scalapb/scalapb.proto";
...

at the beginning of my proto files.

@crispywalrus Thanks for reporting. Are you on protoc 2.6.1 or an earlier version?

We can solve it by providing a second copy of scalapb.proto without that line so it can work with older protoc's. In the mean time you can work around it by modifying your own copy of scalapb.proto.

from scalapb.

Closing due to inactivity. I believe this should work on >=2.6.1

from scalapb.

@thesamet I am using protoc 2.6.1 and getting an error

Import "scalapb/scalapb.proto" was not found or had errors.

I suppose it's related to this issue.

from scalapb.

nvm, I didn't add scalapb-runtime

from scalapb.

@prettynatty how did you add scalapb-runtime?

from scalapb.

@niiamon See "Adding scalapb.proto to your project" at http://trueaccord.github.io/ScalaPB/customizations.html

from scalapb.

@thesamet thanks but I already have that in the project but it's still not working.

@prettynatty I'm actually using your actor-server but I am simply unable to get it to compile due to the protobufs error.

These are some of the issues that complain when I attempt a build:

Error: Import "scalapb/scalapb.proto" was not found or had errors.
Error: Import "sequence.proto" was not found or had errors.

Any ideas how I can get over this?

from scalapb.

@niiamon Will you be able to reproduce this issue on a minimal project and post it on github so we can help debug?

from scalapb.

@thesamet on it. I will revert here as soon as I have something.

from scalapb.

@thesamet Please see this: https://github.com/niiamon/scalapb-test. I have Scala PB added to the project and I have a small proto file in there.

I am still relatively new to Scala and Protocol Buffers as well so any comments are welcome.

from scalapb.

@niiamon , your build.sbt was adding sbt-scalapb instead of scalapb-runtime to the library dependencies. Another unrelated issue that prevented it from compiling was a reference to a configuration named testerpackage, I renamed it to test so the example can fully run.

So the full libraryDependencies in your case should be:

libraryDependencies ++= {
  val akkaV       = "2.3.12"
  val akkaStreamV = "1.0"
  val scalaTestV  = "2.2.5"
  Seq(
    "com.typesafe.akka" %% "akka-actor"                           % akkaV,
    "com.typesafe.akka" %% "akka-stream-experimental"             % akkaStreamV,
    "com.typesafe.akka" %% "akka-http-core-experimental"          % akkaStreamV,
    "com.typesafe.akka" %% "akka-http-experimental"               % akkaStreamV,
    "com.typesafe.akka" %% "akka-http-spray-json-experimental"    % akkaStreamV,
    "com.typesafe.akka" %% "akka-http-testkit-experimental"       % akkaStreamV,
    "org.scalatest"     %% "scalatest"                            % scalaTestV % "test",
    "com.trueaccord.scalapb" %% "scalapb-runtime"                 % "0.5.9" % PB.protobufConfig
  )
}

from scalapb.

@thesamet so I've made those changes here as well. No such luck. I still get the same import was not found problem.

from scalapb.

Works completely fine here when I start sbt and type compile. Have you reloaded sbt after making the change (type 'reload' in an existing sbt session, or just exit sbt and start it again)? If the problem persists after an sbt restart, let's continue debugging it at Stackoverflow (please @thesamet there)
