Managed ClassPath in Runtime + Scala.js causes Intellij to Perform Full Optimized Scala.js build in project load about sbt-web HOT 10 OPEN

@jastice Perhaps IntelliJ should read the value of managedClasspath in Compile rather than managedClasspath in Runtime. AFAICT, the in Compile should contain everything needed for the project model of IntelliJ, without introducing dependencies on potentially expensive things only part of in Runtime.

yes I am seeing something like this too

from sbt-web.

Is there an issue filed with Jetbrains about this?

@wsargent Not that I am aware of, but is it their fault? Afaik, Intellij now uses SBT to resolve dependencies, so it seems like SBT is triggering the build of Scala.js when it shouldn't be?

Is there any progress on this, or should I make an issue at Jetbrains?

I made an issue on Intellij's bug tracker to see if its on their end https://youtrack.jetbrains.com/issue/SCL-12594

IntelliJ Scala developer here.

The IntelliJ import depends on the managedClasspath key indirectly to set the classpath in the IntelliJ-side project model. Thus, if that task has a dependency on package, an import will trigger a full compilation. I currently don't see a way around this except not having this dependency in your build.

@wsargent So it seems like this is purely an issue with sbt-web or Scala-js, if you do this

managedClasspath in Runtime += (packageBin in Assets).value

You are literally telling SBT (and hence Intellij) that in order to evaluate my classpath you need to package all of my assets (which actually doesn't make any sense, they are seperate things).

I have also made an issue with Scala-js

from sbt-web.

@sjrd IntelliJ actually depends on externalDependencyClasspath which depends on managedClasspath to extract the dependencies for all sbt configurations. It's not clear to me we should be excluding specific configurations.

I will involve the sbt guys to see whats their comment here
