You have to set proper source files encoding with:

scalacOptions ++= Seq("-encoding", "your_encoding")

[Alex-Yu]

You have to set proper source files encoding with:

scalacOptions ++= Seq("-encoding", "your_encoding")

It's set but don't help.

[aronfiechter]

I just had the same problem (also, it worked in local but not on GitLab) and adding
scalacOptions ++= Seq("-encoding", "UTF-8")
worked

[bugorz]

I had the same problem and fix it by 1) or 2)

1. Export the locale

    export LC_ALL=en_US.UTF-8
    export LANG=en_US.UTF-8
    export LANGUAGE=en_US.UTF-8

2. Add -Dfile.encoding=utf-8 right after sbt.

[gslowikowski]

@bugorz, in your case the encoding is UTF-8, so you should just add

scalacOptions ++= Seq("-encoding", "UTF-8")

to your build.
