Setting up the project
In order to take part in Scala plugin development, you need to:
Install IntelliJ IDEA 2017.1 or higher with a compatible version of Scala plugin
Fork this repository and clone it to your computer
$ git clone https://github.com/JetBrains/intellij-scala.git
Open IntelliJ IDEA, select
File -> New -> Project from existing sources, point to the directory where Scala plugin repository is and then import it as sbt project.
When importing is finished, in order to get artifacts and run configurations for IDEA project, go to the Scala plugin repo directory and run
$ git checkout .idea
- Open the sbt options (
Preferences -> Build, Execution, Deployment -> sbt)
Use sbt shell for build and import
Global sbt settings -> JVM Options -> Maximum heap size, enter at least
- Select the IDEA run configuration and select the
Debugbutton to build and start a development version of IDEA with the Scala plugin.
To run tests properly, the plugin needs to be packaged. On the sbt shell:
The "fast tests" can take over an hour. To get a quick feedback on project health, run the "typeInference tests"
> testOnly org.jetbrains.plugins.scala.lang.typeInference.*
The project is configured to build and run the typeInference tests with Travis CI, which you can enable in your forks. The full test suite can't currently be run because Travis doesn't allow builds to take that long.
