It connects to a running sbt instance and communicates with it using Language Server Protocol. Atom sends event notifications to sbt (like
didSave), in response sbt recompiles the project and sends back information about warnings and errors which are displayed in Atom:
You can install it using Atom interface or by running this command:
apm install atom-sbt-client
On the first launch it will automatically install its dependencies if needed:
project/build.propertiesshould set sbt version to 1.1.0 or higher)
It should trigger compilation and if there are any errors, you should see them in the gutter and in the diagnostics panel.
Another feature is jump-to-definition, which works for some types in the project.
Note that despite the debug logging in the sbt shell, you can still use it directly. It's just a normal sbt shell which additionally communicates with Atom.
Good catch. Let us know what about this package looks wrong to you, and we'll investigate right away.
