you can Ctrl + Alt + Shift + N and type "main"

I was getting errors about Java 5 language level. Set 7 everywhere in Project Structure and Settings. Getting problem with 'diamond' (

new TreeSet<>()

)

Wrong 1st argument type. Found: java.util.TreeSet<java.lang.Object>, required: java.util.Set<java.lang.Long>

And where are these memory tools? Can't find any mentions in the blog. Actually, new IDEA looks faster, has better icons, and I really like parameter name badges. ❤️

In the debug window

what's am I doing wrong when IntelliJ doesn't show decompiled Kotlin and instead shows the method body as

/** compiled code **/

we're following the precedent set by many other languages, e.g. https://google.github.io/styleguide/javaguide.html#s4.6.2-horizontal-whitespace

Settings | Build, Execution, Deployment | Build Tools | Gradle | Runner | [x] Delegate IDE build/run actions to Gradle

just made the effort to look how to move caret in camel humps mode

@cleiter do you have any insight into what caused that issue? I'm getting the same error.

If we have a maven project that has the

kotlin-maven-plugin

configured with

<jvmTarget>1.8</jvmTarget>

, should the idea IDEA project's Kotlin Compiler > Target JVM Version be auto-synced (upon re-importing the maven project) to the POM so it is also set to 1.8? Currently its not doing such and remains set to 1.6.

@deviant a bit offtopic, but assuming you're using retrofit, I would argue against naming your methods

getSubscriber

for content roots, there's currently a checkbox that you need to check in the "new project" dialog ("create directories for content roots" or something like that). the next IJ version will always create the directories

@semoro I have

-Xmx2048m

I have a data class with 15 properties (I need to write a program to convert a form to usable spreadsheet). IDEA suggests me to replace

list.filter { item -> /* do something with item.pair */ }

to

items.filter { (a, b, c, d, e, f, g, h, i, j, k, l, m, n, pair) -> /* do something with pair */ }

As you can see, pair is the last argument, so this suggestion is bad.

is it a known problem where completions take tens of seconds for kotlin files? it doesn't happen for java files at all. completion is near instant.

I’m running into a minor annoyance where IDEA keeps adding .idea/kotlinc.xml to a non-kotlin project. Unfortunately for reasons

.idea

is not in the

.gitignore

, so I keep having to delete it. Does anyone know if there’s a way to prevent IDEA from re-generating that file in a non-Kotlin project?

ctrl -e..never shows up there

hector

so that's what this guy is called 😄

@janvladimirmostert Did you check https://thoeni.io/post/macos-sierra-java/ ?

@trevjones "refactor function to extension function" already exists. press alt-enter on a parameter and select "convert parameter to receiver"

I am attempting to insert an image in the doc block of a kotlin class via html image tag but the F1 popup is not loading the image. Is this a known issue?

does anyone know how to prevent intellij from importing into a kotlin file (whenever it organizes the imports) java

Map

,

List,

,

String

java classes that kotlin has its own classes for. removing the import doesn't help. It just puts itself back - and of course colours the file also sorts of red since it can't compile anymore.

We are having an issue with compiling kotlin from Intellij after the upgrade to 1.1.2 - basically what happens is that if we make a change in module 1, then module 2 that depends on it does not detect this change. However, the editor does mark the code as red and uncompilable, but "Build Project" will give happily still compile, not seeing the change in module 1. This obviously leads to runtime errors like NoSuchMethod and so on. We tried to reproduce it with a minimal project but were unable, so we are pretty much at a loss as what to do. We have been doing kotlin for more than 9 months, and we are certain it only happened after the upgrade to kotlin 1.1.2. Compiling from gradle also works just fine. Are there any debug switches or anything we can enable so we can get gather more data? As I take it it is very hard to find the bug from the info I can provide so far. I'm thinking maybe some debug output of the classes that are being recompiled upon "Build Project"?

Is there a way to see Kotlin

TODO()

functions in IntelliJ TODO window? I tried adding a pattern like

\bTODO\s*\(

however it does not seem to work.

Hi all, not sure if this is the correct place to report this. I am using Kotlin plugin 1.1.2 with Android Studio 2.3-3. I wrote:

if (x !is String) return

and the IDE suggested that I should replace

if

operator with elvis. I tried replacing it with

(x is String) ?: return

but got a warning "Elvis operator always returns the left operand of non-nullable type Boolean". The same statement produces the same error in try.kotlinlang.org.

@mingkangpan Be aware your code is not safe. I would rewrite this loop to avoid the

!!

I have sometimes performances issues in intellij. I added a .vmoptions files as indicated here: https://intellij-support.jetbrains.com/hc/en-us/articles/207241235-Reporting-performance-problems?page=2#comments

this is most likely caused by https://github.com/Triple-T/gradle-play-publisher and has nothing to do with #intellij

what does this have to do with kotlin?

it also seems to contradict itself:
