Scalapb: Unresolved Dependency - Documentation Issue

[dhuadaar]

I was trying to use ScalaPB via the standard SBT project as mentioned on the official website. My sbt version is 0.13.11. I am getting a an error as follows :

[error] (*:update) sbt.ResolveException: unresolved dependency: com.trueaccord.scalapb#sbt-scalapb;0.4.20: not found
[error] Total time: 14 s, completed 27 Jun, 2016 3:47:37 AM

Does it print which URLs it is looking for it?

Hi, I met the same error while trying to add dependency, the complete message as follows:

Look forward to your reply, thanks.

Can you post a full project? I am unable to reproduce this issue.

[kdcc]

Since the full project is large and local, not so convenient to post, I list the configuration files as follows.

In scalapb.sbt:

libraryDependencies ++= Seq(
"com.trueaccord.scalapb" %% "compilerplugin" % "0.4.20",
"com.github.os72" % "protoc-jar" % "3.0.0-b2.1"
)

In build.properties:

Activator-generated Properties

Wed Jul 22 13:20:51 CST 2015

template.uuid=a91771f5-1745-4f51-b877-badeea610f64
sbt.version=0.13.11

I haven't add the following statements to build.sbt yet:

import com.trueaccord.scalapb.{ScalaPbPlugin => PB}

PB.protobufSettings

Btw, the following dependency works:

"com.trueaccord.scalapb" %% "compilerplugin" % "0.4.20"

If anything else I could supply, just tell me.
Thanks.

[thesamet]

Do you have the following line in your project/scalapb.sbt:

addSbtPlugin("com.trueaccord.scalapb" % "sbt-scalapb" % "0.4.20")

[kdcc]

Oh, totally my mistake. I placed scalapb.sbt in wrong path.
And under your guidance it works now!
Very grateful for your timely help!
Thanks!

[thesamet]

@PeeyushAgg can you post an example project with this behavior?

I set up a project with the files you provided and ScalaPB loads correctly.

@PeeyushAgg , when SBT is unable to resolve a dependency it prints a few lines that says where it's looking for it. Here is what it might look like:

[warn]  module not found: x#y;0.1.4
[warn] ==== typesafe-ivy-releases: tried
[warn]   https://repo.typesafe.com/typesafe/ivy-releases/...
[warn] ==== sbt-plugin-releases: tried
[warn]   https://repo.scala-sbt.org/scalasbt/sbt-plugin-releases/...
[warn] ==== local: tried
[warn]   /home/thesamet/.ivy2/local/...
[warn] ==== public: tried
[warn]   https://repo1.maven.org/maven2/com/...

Most likely somewhere in your environment (maybe in ~/.sbt, or in another sbt file) you have a resolver := ... such that maven central is excluded. All versions of sbt-scalapb are there: https://repo1.maven.org/maven2/com/trueaccord/scalapb/sbt-scalapb_2.10_0.13/

[dhuadaar]

This one helped. Issue resolved.

[mbesida]

According to the doc added

addSbtPlugin("com.thesamet" % "sbt-protoc" % "0.99.1")

libraryDependencies += "com.trueaccord.scalapb" %% "compilerplugin" % "0.5.43"

to scalapb.sbt, added

PB.targets in Compile := Seq(
  scalapb.gen() -> (sourceManaged in Compile).value
)

to build.sbt. On sbt update I got unresolved dependency: com.trueaccord.scalapb#scalapb-runtime_2.12;0.5.43
What am I doing wrong?

[thesamet]

We're supporting Scala 2.12 starting from version 0.5.45 (just change the compilerplugin version)

[mbesida]

@thesamet thanks, it would be good to refelect this on the mentioned doc site
