    sorry, meant 2.13.6, not 2.16.6.

    i'm using the latest ultimate EAP (IU-212.5284.31) with the latest scala nightly plugin (2021.2.443). and the package search plugin is bundled with the EAP release. i can see the package search plugin settings in the settings window. i have a trivial "hello, world" scala 2.16.6 sbt project. and i've read https://blog.jetbrains.com/scala/2021/07/09/package-search-integration/, which says package search should work for scala. but for the life of me i can't get it to work at all. it makes me feel insane. thoughts/comments?

    Hello @mtk, I am also testing this with the latest ultimate EAP and the latest scala nightly and scala version 2.13.6 (the same versions with yours). and I can manage to use package search for it. So if it is okay for you, could you please send me the link to your project for me to test it out on my machine? Furthermore, additional info like environment you are running, enabled plugins, etc. would be very helpful.

    the env is windows 10 (although i've been using unix since 1982 :-)). it is completely up to date. you can clone github.com/mtk/BareBones for an example that fails (for me). i tested against a fresh idea EAP install, added the scala plugin, switched to nightly and updated.

    btw, if i do a shift-shift search and enter 'package search', i only get four responses: 1) a link to the package search settings screen, 2&3) a check for new dependency versions toggle (one each for maven & gradle, both on), and 4) a 'package search plugin' toggle (also on). no other actions.

    how to set the label position or location?

    val a=new Label {
    
            //locationOnScreen =new Point(400,600)
            //location= new Point(400,600)}

    I got an error :Reassignment to val location.

    Good morning! sbt v1.6.0-M1 was just released, it merged some fixes relating to the BSP support (mainly, allowing using Rebuild project from IntelliJ as well as compilation progress reports, in addition to other fixes). I wrote a small blog post about how to use BSP in IntelliJ, if you're not using it already! https://hmemcpy.com/2021/09/bsp-and-intellij/

    I am always getting ^^^ when I open Intellij. I used the EAP version at one point, but I haven't for a few months. I tried uninstalling, and then reinstalling the plugin. Any ideas on how to fix this besides updating to the EAP version of Intellij?

    Has anyone run into a case where Intellij insists on building an sbt subproject as scala3 even though the subproject itself is explicitly set to scalaVersion := "2.13.6", and know of a fix? Sbt itself is not confused.

    I gave my plugin a shot at building with the newly released 2021.3 EAP (and scala-plugin 2021.3.4) - I'm getting this error on my CI now:

    my_test failed: com.intellij.testFramework.TestLogger$TestLoggerAssertionError: jarFiles is not set for PluginDescriptor(name=IDE Features Trainer, id=training, descriptorPath=plugin.xml, path=~/.zio-intellijPluginIC/sdk/213/plugins/featuresTrainer/lib/featuresTrainer.jar, version=213.3714.440, package=training, isBundled=true), took 0.001 sec

    Anyone know what this might be?

    Unrelated to Scala but I'm failing at googling: IDEA indicates lines changed since last git commit in the gutter, is there a way to also indicate lines that changed in the last commit from previous?

    Not on exactly on the gutter, but if you turn on git annotations, lines changed in the last commit are highlighted:

    Hi everyone! We're starting to use Lagom in our company and I can't seem to configure how to let SBT know that our project uses java 11. Every time I run sbt sync from IDEA, the project settings roll back to java 8.
    We currently have configured the build as so: Compile / javacOptions ++= Seq("-source", "11", "-target", "11")

    Hi All, I have big problem with Scala 3 plugin, my project very often use constructions like:

    object Reproduce {
      case class User(id: UUID)
    
      sealed trait TestBase
      case class Test01(data: String, id: Int) extends TestBase
    
      def render: PartialFunction[(TestBase, User), String] = { case (base: Test01, user) =>
      }
    }

    My expectations variable base have type Test01 and code completion + code navigation + refactoring + etc. works, but latest Scala plugin, sadly yet, think that base have type Any in result code editing is very painful, refactoring not work and many other problem.

    is there any one who know the difference between "this.type" and "this"?
    as far as i understood.. it's no difference when it use for return like this..

    abstract class Abstract0 {
    def setOption(j: Int): Any
    }

    class Concrete0 extends Abstract0 {
    var i: Int = 0
    def setOption(j: Int): this.type = {i = j; this}
    }

    class Concrete1 extends Abstract0 {
    var i: Int = 0
    def setOption(j: Int):Unit = {i = j;}
    }

    class Concrete2 extends Abstract0 {
    var i: Int = 0
    def setOption(j: Int) = {i = j; this}
    }

    object testfor2 extends App{

    val xx = (new Concrete0).setOption(1)
    val xxx = (new Concrete0).setOption(1).setOption(1)
    val xxxx = (new Concrete1).setOption(1)
    val xxxxx = (new Concrete2).setOption(1)

    }

    this.type is the type whereas this is the instance.
    In case of inheritance, this.type is the type of the implementing class, not the trait / abstract class.
    Allen.Yoon
    @ironmaskara
    hmm.. I can't catch a meaning of type and instance to this case.
    if I get returns [using "this.type" and set this value in "val x"] and [using "this" and set this value in "val xx"], then.. I guess these are no difference.

    aha... wait..
    I think... you said... if we use "this.type" for return value in abstract class.. and concrete class extends this one.. and return "this" and.. abstract class's return type this.type will point out to implementing class not the trait/abstract class

    am i right?

    Hey, I am using Scala nigthly 2021.2.449 and scalafmt 3.0.6. It seems to me (but I am no 100% sure) that since this nightly plugin build IDEA forces import optimize on save, even though it is disabled. Is it related to optimise import on the fly?
