    Hello, everyone! I have a question about creating Kotlin test code. When I create a Kotlin test, both a TestClass.java file and a Kotlin JUnit5 Test Class.kt file are generated. However, when I disable K2 mode, only the TestClass.kt file is created. Is there any solution to prevent the TestClass.java file from being generated, or to ensure only the Kotlin test file is created regardless of the K2 mode?

    What is the reasoning behind this? I don't think it makes it clearer. If i have a nullable boolean, then 
    ?: false
    implies "default to false". I find this more readable than 
    == ...
    .

    In IntelliJ my 
    .main.kts
    scripts don't know about the Java stdlib - lots of: Cannot access 'Object' which is a supertype of 'ObjectMapper'. Check your module classpath for missing or conflicting dependencies. Cannot access 'Serializable' which is a supertype of 'ObjectMapper'. Check your module classpath for missing or conflicting dependencies. I can't work out how to tell the script about them?

    is there a way to write live templates that reference the FQN of Kotlin extension functions? So that they will be auto-imported

    Are there any issues filed already for 
    switcher
    and 
    recent files
    behavior on IJ 2025.2 EAP? EAP 1 was completely broken, EAP 2 is broken as well but a bit less • EAP 1 would seemingly populate 
    recent files
    dialog with indexed files? It would show tons of generated files that were never open. In EAP 2 I still get unopened files, but only sometimes and it's just one file • in EAP 2 the 
    switcher
    (ctrl + tab on mac) doesn't show recently opened file anymore, and when invoked doesn't return the cursor to the place it was previously. In 2025.1.x, pressing 
    ctrl + tab
    repeatedly will toggle between two files, in 2025.2 the 
    switcher
    files don't match recent files at all if not I'll file some later, just curious if there's some new setting or something that I'm missing

    I like how I am able to jump to a method when using JUnit's MethodSource, is there a way to define the same behaviour for a custom annotation, also requiring a method name?

    Is there a way to make declarations which are only used in tests be highlighted as unused? We're actively adding unit tests in our large project and I'm afraid this will result in a lot of unused code in the long term

    Is there a way for Intellij to warn when commiting only specific TODOs? For example, I don't want it to complain on TODO and FIXME, but would like to stop the commit on NOCOMMIT tokens in the code? As far as I can see, either it checks for any possible TODO or none at all...

    Hey guys. After installation of the Kotlin Multiplatform Plugin to IntelliJ IDEA 2025.1.1.1 cannot find option 
    Compact Middle Packages
    in Project tab. Does anybody have this problem?

    Is this a known (k2) bug?
    Copy code
    data class Foo(val id: String) {
    override fun toString(): String = id
}

 class Bar(val id: String)

class Test
class Test2

fun main() {

    val foo = Foo("1")
    val bar = Bar("2")

    // why is not flagged as well?
    if(foo != bar) println("not equal")

    if(Test() != Test2()) println("not equal")
}
    The first condition is not flagged. The issues seems to affect only cases where the left-hand side argument of != is a data class.

    Hello, is this a known bug? Renaming a Kotlin field is not executed correctly in Java. It drops the 
    get
    prefix. Are there any known workarounds? Version: IntelliJ IDEA 2025.1.2 (Ultimate Edition) Build: #IU-251.26094.121, built on June 2, 2025 Kotlin Compiler: K2

    Feeling quite frustrated at the moment; I'm using IntelliJ 2025.1.2 and I can't get the 
    .idea
    folder to show up in the project files view. I can see it in Android Studio, if I open that instead, and even if I add a custom scope to the project it still won't show up in that custom scope. Does anyone know how to set this up? The new Kotlin Multiplatform plugin requires some .idea configuration to allow xcode run configurations to become visible, and it's very annoying needing to open the files externally to edit them.

    I have a positive message. I'm happy to see that type-aware completion (i.e. the feature that is bound to control-shift-space by default) has finally been implemented in the latest EAP. Now, I have a question for everybody: During the time when it wasn't available, I was quite frustrated and stayed on K1 for quite a while because of it. When talking to JB about it, I learned that they implemented features based on their statistics, and implemented features that was used a lot first. That makes sense, but it seems weird to me that type-aware-completion was only used by a single-digit-percent of users. If people are not using it, then what do they use?

    It seems I can't debug a

    script in IntelliJ IDEA ... it runs, but no breakpoints ever trigger anything. Is that a known limitation? (2025.2 EAP with K2)

    Getting these sorts of erroneous type errors all over a mixed Java/Kotlin module. (required type: T provided: T 🙃) Compiles fine however. Build #IU-251.26927.53 - ❗*Only occurs when K2 is enabled* ❗- known issue?

    I have a kotlin js project that builds fine using gradlew clean build. But in IntelliJ, the dependencies are not resolved, so I get for example "Unresolved reference: react" Can anybody give a hint what might be wrong? Tried already invalidate cache and restart, unlink / relink project, refresh gradle dependencies, delete .gradle and .idea folders Does not happen with IntelliJ 2024. Maybe our KotlinJS project is too old and no longer compatible with new intellij versions :(

    What's the status with 
    main.kts
    and K2? I just had to disable K2 again to get autocomplete 🤔 on 
    IntelliJ IDEA 2025.2 EAP
    . Am I missing something? Can you do 
    main.kts
    with K2?

    I really enjoy being able to write 
    .kts
    scripts instead of `.sh`; keeping more complex scripts in a powerful, familiar language. Unfortunately the usefulness of 
    kts
    is unduly limited by IntelliJ IDE's failure to resolve symbols across 
    @file:Import
    dependencies - meanwhile the scripts still run fine. This problem has only become more impactful with junie Junie; as the agent sees 'unresolved' false positives and erroneously act upon them, struggling for a fix that never comes. kodee sad This limitation is very sad, given it's been hanging for over 2 years... KTIJ-16352 Scripts / IDE: unresolved reference when trying to import file in main.kts scripts with @Import annotation Any insights into this issue in or outside of JB? Is scripting just abandoned beyond what's needed for Gradle? Such a shame, it's a killer feature in my book. Slack Conversation

    Is there any table which Kotlin version is used by the Kotlin IntelliJ plugin? I want to use kotlin.k2.only.bundled.compiler.plugins.enabled=false but I needed to migrate to the 2.2.0 FIR api (using context parameters in the FIR checkers), but IntelliJ does not use the new api yet, so my checker does not work.
