My ide started to show all Java imports in a kotlin project as red. It's for sure a false alarm because the build is fine. Invalidating caches didn't solve it. Can someone offer any hint on how to try to debug such issues? I don't even know where to start (it's a gradle multi project build).

first thought when i saw a new IDEA EAP announced on twitter: “I wonder what ancient kotlin version it will use.” now i know the answer. 1.5.10.

Why is Intellij giving this hint? Does it prefer I remove the

==

check, and just leave the

else

branch?

If I have a simple one line function e.g.

fun foo() = "hello"

And I want to change this to have a body, because I need to add more lines. e.g

fun foo(): String {
    return "hello"
}

Is there a refactoring that can do it for me?

I'm using Idea Ultimate 2021.3.2 and running a native unit test, and for some reason the gradle task macosX64Test is showing no stdout stuff from the unit test, just gradle-level messages. Strings from a println() are just not displayed at all, and text from an assertEquals failing is also not shown. Run window just indicates the test either failed or succeeded, making the unit test not very useful :-). Anyone else having trouble seeing stdout in the Run window during native unit tests?

If I open a .class file that was compiled from kotlin, IJ tries to decompile it as a kotlin, although

// Implementation of methods is not available

How do I disable that and use standard java decompiler/bytecode viewer? (the option `Show bytecode`is also disabled right now).

Hi, why does showing class diagram is not available for external definitions in a Kotlin/JS project ?

Hi, I have an issue with auto adding imports, which is really annoying. It automatically adds import and prefix variables it in the rest of file, for example: When I have a code:

class (
 val email:String
) {

fun doSomething() {
   print(email)
}

Then I decide not to define property

email

in constructor and remove

val

, IDEA automatically change all occurrences of

email

like this:

import kotlinx.html.InputType

class (email:String) {
   fun doSomething() {
      print(InputType.email)
   }
}

I am facing it in lot of similar cases, usually related to enums. I have option `Editor->General->Auto Import->Add unambiguous imports on the fly`disabled.

Hey folks, I'm wondering if anyone else has seen a similar issue where IntelliJ doesn't recognize some Kotlin/ktor code that compiles fine. For example in my screenshot it complains about a type mismatch yet this code compiles and runs fine, and was just based on some examples from the ktor client docs. Does anyone have any advice for figuring out this issue or tracking down why this happens in IntelliJ? I am running IntelliJ IDEA 2021.3.1 with openjdk-17 and Kotlin 1.6.10. Please let me know if there is a better place to ask questions like this as well. Screenshot in thread

Hi, I've created a Maven project which uses Kotlin and does not use Lombok, but when I open it I get the warning "Lombok requires enabled annotation processing: Do you want to enable annotation processors?". Searching every file in the project for "lombok" returns no results. Is this a known issue?

Hi , does IntelliJ performs better on M1(pro|max) than M1 ? I know pro|max performs much better than M1 on job of video editing or gaming, but I don’t do that. I just a developer , with tools of IntelliJ / Java / Kotlin / docker (and maybe android dev in the future) … etc. I am using M1 mini now , and it performs well. But for laptops , are there any performance differences among M1/Pro/Max (with same 16G ram) ?

Is there a way to update the Android Support Plugjn for Intellij ?

Does anyone know if it's possible to use

ReplaceWith

to refactor a

package

? In Arrow we need to migrate a DSL to a new package, but

ReplaceWith

seems to be broken. https://github.com/arrow-kt/arrow/blob/main/arrow-libs/core/arrow-core/src/commonMain/kotlin/arrow/core/computations/either.kt#L109

I have two Kotlin Gradle projects open in a single Idea project.

MyApp.kt

in Gradle project A imports

MyLib

from Gradle project B. If, from

MyApp.kt

I do "Go To -> Declaration or Usages" on

MyLib

, should it open

MyLib.kt

in project B? Currently it opens up a decompiled bytecode. This worked with Maven, but Idea does not seem to be making the connection between Gradle projects.

It's possible to search for usages of a data class constructor by positioning the cursor inside the constructor brackets and using "Find Usages". However, this doesn't work for value classes. Is this a known issue? Not seeing anything related in YouTrack.

Anyone knows how IntelliJ picks up my JAVA_HOME? Looks like it's able to pick up what I put in

.zshrc

even though it's not (always) started from the command line? Am I just lucky or do "graphical" apps also inherit the shell env variables somehow on MacOS?

Using Datagrip or IJ Ultimate with datagrip plugin: Is it possible to write custom sql extractor plugins/scripts in Kotlin? Current documentation only mention groovy (or JavaScript)?

Is the issue of the source code not being shown on demand going to be sorted during one of the Kotlin 1.6.x releases? When using ctrl+b on an element in a Kotlin source file only the metadata is shown, eg:

// IntelliJ API Decompiler stub source generated from a class file
// Implementation of methods is not available

package io.gitlab.embedSoft.lvglKt.core.lvglObject

public final enum class LvglPart private constructor() : kotlin.Enum<io.gitlab.embedSoft.lvglKt.core.lvglObject.LvglPart> {
    MAIN,

    SCROLLBAR,

    INDICATOR,

    KNOB,

    SELECTED,

    ITEMS,

    TICKS,

    CURSOR,

    CUSTOM_FIRST;
}

I wonder if for kotlin projects go to class should also find top level functions and top level values. (it could be renamed to go to top level object) I know that i can use go to symbol, but that finds way more things.

Hi, simple question, when opening a folder 1 containing only a sub-folder 2 with code, is there a way to directly open the sub-folder 2 with the code as the folder 1 doesn't contains anything appart the sub-folder 2 ?

Is the Kotlin code formatter used in the IntelliJ plugin available as a separate jar on Maven Central?

For a Maven project, when right-clicking pom.xml and selecting "Show effective POM", is it possible to get it to show which parent POM a certain line comes from?

No longer seeing "Put arguments on different lines" action. Only when line is too long, but I very often want to apply this action when line is less then wrap width (for example when working with Compose). Is it some bug or something configurable? (can't find where)

Something I've been noticing since Kotlin 1.6.20 in IJ is that building the project now seems to use Ant rather than Gradle, even though the project's build script is

build.gradle.kts

. Why is that?

Code completion seems to be broken when using Kotlin 1.6.21 with the linuxX64 target (may also be a problem with the other Linux targets). For example, in the platform.linux package only a single function is listed (mq_open - https://man7.org/linux/man-pages/man3/mq_open.3.html ) with most of the other items being constants (like KDSETMODE for example). If some other symbol (eg mq_send - https://man7.org/linux/man-pages/man3/mq_send.3.html ) has its import inserted by IntelliJ (via Alt+Enter) then that symbol now appears in the code completion list.

Is there a way to populate 'Favourites' from Gradle configuration? Use case: Our project module structure enforces '_Clean architecture_' so that each major feature module contains a '_Presentation_', '_Domain_', and '_Service_' sub-module. While this has its benefits; a down-side is ergonomic navigation between files of the feature in the IDE, due to all the intervening

/src/main/kotlin

folder cruft etc. A code-defined, custom project view that presents the presentation/domain/service packages beside each other would resolve this problem. Favourite list provide a good enough User Experience, but AFAIK they can't be populated by Gradle code, so can't live alongside the code and be shared with the team. Any solutions?

Is it not possible to create a Gradle based Kotlin Module , in intelij idea 2022? it seems to only default to Intelij build system

Can I debug the compilation process? I've set these options in

gradle.properties

and attached the debugger after run:

org.gradle.debug=true
org.gradle.debug.server=true
org.gradle.debug.suspend=true

...but for some reason the debugger doesn't 'break' on this Exception which is occurring in a JS build:

e: java.lang.AssertionError: Assertion failed
	at org.jetbrains.kotlin.ir.backend.js.transformers.irToJs.JsAstUtilsKt.translateCallArguments(jsAstUtils.kt:341)

I have previously used the debugger successfully to debug Gradle sync issues using the same method... is there something going on with internal process launching that's 'hiding' the JS compiler's activity from the debugger?

Anyone else’s IDE won’t import

kotlinx.serialization.Serializable

or is it just me? When I type

@Serializable

and autocomplete it it writes

@kotlinx.serialization.Serializable

instead of importing it. Doesn’t do it for any other class/annotation. Then if I try to hit

Alt+Enter

on it, it doesn’t offer to add the import there either. Weird
