Update: Known IDEA issue: https://youtrack.jetbrains.com/issue/KTIJ-10228. Thanks #somethingsomething for the pointer.
I'm learning Kotlin and in one of the examples, there's the following code:
listOf("carrot", "cheese", "chocolate")
Putting it in IDEA and following up listOf source (control/command + click) leads to:
Which is very nice. I can see actual source code and learn from the origin. But!!!
When further clicking on asList leads to:
But here, there's no source code. Dead end :(
The expect keyword means that the actual implementation is platform dependent.
Is there a way to look up the code, connecting it to IDEA? For example, if I'm on a Mac, how do I see the local implementation and connect it to IDEA using control/command + click? Thanks.
I've searched for similar questions in SO. Found some related to dependency definitions in pom to see the source code instead of decompiled code. My problem is different. I actually see the source code - not any decompiled code. My specific problem is that not all source code is shown. Specifically missing the platform dependent source code.

Going off the documentation here are Modules and other Geb DSL not expected to be recognized within a Spock Spec with IntelliJ? This makes using Geb with IntelliJ a bit cumbersome with no DSL reference. I noticed from this question that the asker did some custom work to get IntelliJ to wrap and notice the Geb DSL.
My questions is am I doing something wrong or is this expected and has there been any progress on getting the Geb DSL recognized by IntelliJ?
If not does anyone have a workaround for this issue/limitation and or another IDE that does recognized the Geb DSL?
IntelliJ has support for Geb DSL, I've been using it for years and there are even tests in IntelliJ's codebase that confirm it's there.
If you could share how your code looks like and what exactly does not work for you then maybe we can find a problem with your setup or expectations. It would also be good to know whether you are using community edition or professional edition.
Please note that the issue discussed in the question you linked to has been fixed by me in this PR and is no longer present since IntelliJ 2018.2.
EDIT:
After reading your comments under my response I now understand what the problem is. Your expectation is that IntelliJ will be able to figure out what the page type at runtime is and provide you with autocompletion. I'm afraid that is simply not possible - you need to track current page instance in your code for IntelliJ to be able to infer types.
Note that tests in geb-example-gradle are written in the very concise, yet dynamic style which means that IntelliJ is not able to infer types. What you need to do is to use the strongly typed style as described in the documentation. That section of the docs could do with a bit of improvement because it's not precise - I've created a Github issue to track that.
Essentially, if you tweak GebishOrgSpec from geb-example-gradle to:
class GebishOrgSpec extends GebSpec {
def "can get to the current Book of Geb"() {
when:
def homePage = to GebishOrgHomePage
and:
homePage.manualsMenu.open()
then:
homePage.manualsMenu.links[0].text().startsWith("current")
when:
homePage.manualsMenu.links[0].click()
then:
at TheBookOfGebPage
}
}
then IntelliJ will provide you with autocompletion.
I am trying to learn Kotlin by following the tutorial. I managed to get the plugin installed in Intellij. But I am not able to get the first exercise to run. When I click on the little checkbok it tells me
Failed to launch checking. See idea.log for more details.
(I created another blank project and type the same simple exercise in a scratch file and it works.)
link to docs
Try to check the project's is linked to the right JDK. Open File/Project Structure/Project. Then select the correct Project SDK.
To me, this helped. But as others have pointed out, please, share your idea.log, which you can find at Help/Show log in [whatever text editor it's associated with].
Coming from Eclipse world, I really miss this important feature where Eclipse suggests if particular package needs to be imported for compilation error
e.g.
new ArrayList , this simply says Can't resolve symbol
'ArrayList' but doesn't suggest which package to import like eclipse
does.
Is this bug with IDEA or some setting needs to be done in it ?
[Solution]
The problem turns out be bad UX from IDEA
If user does mouse over, it show error message as per above screen shot
If user puts mouse somewhere else; it suggests package to import sometimes. It's not as friendly as Eclipse though
I've posted answer in bottom part of question. IDEA has got confusing & not so user friendly UX which gives hints about package to import.
I find it more useful in Eclipse, hope IDEA team will fix this

I have a new Java project started that is using Gradle (version 3.4.1) and IntelliJ. I used gradle init at the command line and then imported the project into IntelliJ, using the default wrapper (which is recommended, according the the IDE).
I have the following in the build.gradle file:
jar {
manifest {
attributes 'Main-Class': "com.testerstories.textadv.Voxam"
}
}
The attributes line, however, provides a consistent warning that says:
'attributes' cannot be applied to '(['Main-Class':groovy.lang.GString])'
The issue appears to be "incompatible types." But it's unclear what "attributes" is being "applied to". I would presume the manifest block. But then ... what does it want me to do exactly?
I realize this is a warning and I could just ignore it. I also realize I can block inspections. But in all the discussions about this, and I realize there are a few (although most of those seem to deal with 'groovy.lang.Closure'), I have yet to find anything that unambiguously states quite simply what the actual issue is and how to resolve it. I say "resolve it" in contrast to (1) just cover it up or (2) pretend it doesn't exist.
It concerns me that something that appears to be very basic Gradle usage is not recognized or is indicating a problem in one of the core IDEs that supports Java.
Finally, I'll note that before adding to the StackOverflow space, I had asked JetBrains support and their answer was to make sure my .iml file was indicating a "JAVA_MODULE" rather than a "WEB_MODULE", which I did verify. Their next answer was that I needed to provide (quoting directly) a "namespace to resolve the ambiguity, which should resolve erroneous type errors." Ironically, perhaps, that reply needed some ambiguity resolution of its own, but I have gotten no further responses.
UPDATE (RELATED TO ABOVE; BUT DIFFERENT CONTEXT)
If I use something like this in my Gradle:
systemProperties(System.getProperties())
I'm told that getProperties() is an ambiguous method call. Originally I thought that was unrelated to my original issue, but the IntelliJ inspector reports that this is also an issue with incompatible types.
The conclusion I'm reaching -- and what will probably be the "answer" -- is that Gradle and IntelliJ just don't play nice with each other in a variety of contexts.
I've been trying to use the JFace ProjectionViewer to implement folding in a standalone Java app. I got the idea from this article:
http://www.eclipse.org/articles/Article-Folding-in-Eclipse-Text-Editors/folding.html
However the source code provided with the article is for an Eclipse plug-in, not for a standalone.
The particular problem I'm having is that I can't get the VerticalRuler to respond and cause folding/unfolding.
Since I get the expected results, i.e. line numbers in the ruler, when I change from using a VerticalRuler to a LineNumberRuler while leaving everything else the same, I think my problem is specific to the implementation of the relationship among the ProjectionViewer, the VerticalRuler, and the Annotations.
My exact question is whether anyone has gotten this to work in a stand-alone code and, if so, how?
