+`metals` requires either an SBT project, a Mill project, or a running Bloop
+server.

+  Type: |String|
+  Default: `''`
+
+  By default the project root is found by searching upwards for `build.sbt`,
+  `build.sc`, `.bloop` or `.metals`.
+  If the project root is elsewhere, you can override the project root
+  directory.
