Scala is officially supported on Scalingo.
It uses sbt 0.11.0+.
$ ls Procfile build.sbt project src $ scalingo create my-app $ git push scalingo master ... -----> Scala app detected -----> Building app with sbt -----> Running: sbt compile stage
The buildpack will detect your app as Scala if it has the
project/build.properties and either
*.sbt in the root directory or
.sbt/*.scala. It vendors a version of sbt and your
.ivy/cache into your container. The
.ivy2 directory will be
cached between builds to allow for faster build times.
In some cases, builds need to clean artifacts before compiling. If a clean
build is necessary, configure builds to perform clean by setting
$ scalingo env-set SBT_CLEAN=true SBT_CLEAN has been set to true.
All subsequent deploys will use the clean task. To remove the clean task, unset
$ scalingo env-unset SBT_CLEAN SBT_CLEAN has been unset.
