[GRADLE-3257] IntelliJ project generation for Scala projects doesn't support IntelliJ 14 Created: 05/Mar/15  Updated: 10/Feb/17  Resolved: 10/Feb/17

 Description   

.iml has changed from

<component name="FacetManager">
<facet type="scala" name="Scala">
<configuration>
<option name="compilerLibraryLevel" value="Project" />
<option name="compilerLibraryName" value="scala-compiler-2.11.5" />
</configuration>
</facet>
</component>

to

<component name="NewModuleRootManager" inherit-compiler-output="true">
...
<orderEntry type="library" name="scala-sdk" level="project" />
...
</component>

Until Gradle supports the new format, one has to follow a semi-automatic conversion process after each regeneration. It's now also possible to configure the sdk on the module rather than project level, which might be a better fit for Gradle.

Here's my workaround:

ext.scalaVersion = '2.11.4'

idea.project.ipr.withXml {
Node scalaSdkLib = it.node.component.find

{ it.@name == "libraryTable" }

.library.find

{ it.@name == "scala-compiler-$scalaVersion" }

scalaSdkLib.@name = "scala-sdk-$scalaVersion"
scalaSdkLib.@type = "Scala"
Node compilerClasspath = scalaSdkLib.appendNode("properties").appendNode("compiler-classpath")
def classesRoots = scalaSdkLib.CLASSES[0].children()
classesRoots.each

{ compilerClasspath.appendNode("root", [url: it.@url - '!/']) }

classesRoots.clear()
}

gradle.projectsEvaluated {
allprojects {
idea.module.iml.withXml {
def facetManager = it.node.component.find

{ it.@name == 'FacetManager' }

def scalaFacet = facetManager?.find

{ it.name() == 'facet' && it.@type == 'scala' }

if (scalaFacet != null) {
facetManager.remove(scalaFacet)
it.node.component.find

{ it.@name == "NewModuleRootManager" }

.appendNode("orderEntry", [type: "library", name: "scala-sdk-$scalaVersion", level: "project"])
}
}
}
}

Thanks. Turns out that .ipr generation needs to be changed as well.

As not everyone will be on IntelliJ 14+, the target version should be configurable, e.g. 

 allprojects { apply plugin: "idea"; idea.toolVersion = 14 }

.

As announced on the Gradle blog we are planning to completely migrate issues from JIRA to GitHub.

We intend to prioritize issues that are actionable and impactful while working more closely with the community. Many of our JIRA issues are inactionable or irrelevant. We would like to request your help to ensure we can appropriately prioritize JIRA issues you’ve contributed to.

Please confirm that you still advocate for your JIRA issue before December 10th, 2016 by:

  • Checking that your issues contain requisite context, impact, behaviors, and examples as described in our published guidelines.
  • Leave a comment on the JIRA issue or open a new GitHub issue confirming that the above is complete.

We look forward to collaborating with you more closely on GitHub. Thank you for your contribution to Gradle!
