When pasting Kotlin code from another class with "static" imports, e.g.:
#SpringBootTest(webEnvironment = RANDOM_PORT)
I would like IDE to add import like this
import org.springframework.boot.test.context.SpringBootTest.WebEnvironment.*
But instead of that IntelliJ Idea (version 2018.1.1) changes the pasted code to
#SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
and adds
import org.springframework.boot.test.context.SpringBootTest
Is that bug or feature and can I change it?
This is a shortcoming of the current version of the Kotlin plugin. I've filed an issue to improve the behavior in future versions.

I found this tutorial from JetBrains: https://www.jetbrains.com/help/idea/create-your-first-kotlin-app.html?section=Gradle%20Kotlin
It is dated August 19th, 2020.
I am using the same IntelliJ IDEA version as in their documentation: 2020.2.
However, my project creation wizard looks quite different from theirs.
They provide this screenshot:
But for me, it looks like this:
and when I click on Next:
I don't see where I can choose the Console Application template, or Gradle.
I found a second tutorial - https://kotlinlang.org/docs/tutorials/jvm-get-started.html , which shows yet a third variation of the New Project wizard:
Are the tutorials out of date? Am I doing anything wrong? How do I create a Kotlin project, based on a console application template, with Gradle?
The wizard you have seems to be obsolete now. There was a brand-new one, released as a part of Kotlin 1.4 recently(see here). Most probably, the problem is caused by the Kotlin IDE plugin being outdated or something. Please try to delete in and re-install using the Preferences -> Plugins menu. Comment here with the results, please. I'd like to know if this would help.
Indeed it's quite weird, I've never seen the dialog to look like yours (mine looks like the one in the tutorials). However, choosing the template doesn't do anything special - it simply creates the main file, which you can do so yourself.
So create a new project with the "JVM/IDEA" option. If it already opens up a main.kt file, you don't need to do anything else. If it didn't, look in the src folder - you should see a folder named main with a folder named kotlin (with a blue icon instead of grey) inside - here's where you wanna create your main file (right click -> new kotlin file/class -> main.kt and make it a file, not a class). Finally, put this in the file:
fun main(args: Array<String>) {
println("Hello world!")
}
Note: if you don't have a kotlin folder, create the file in the folder with the blue icon (might even be src). Also, if this doesn't use Gradle (for some reason), create a Gradle project instead, and at the "Additional libraries and frameworks" option, uncheck Java and check Kotlin, then continue with creating main.kt if it isn't created.
You may create a Kotlin + gradle project from the terminal:
$mkdir myProject; cd myProject; gradle init
follow the tutorial.
And then start the Intellij & open the dir
You're good to go
Same process like this
The same happened to me but I figured out how to fix it:
Just disable Material Theme UI.
My team members and me often face the problem in Intellij that we cannot import some classes via Alt+Enter because Intellij hasn't indexed them successfully.
Our set up
We have different Flutter projects which belong and work together.
ProjectFolder:
our_project/customer_app
our_project/provider_app
our_project/server_app
our_project/model_app
Some of these projects have dependencies to other projects which are declared in the pubspec.yaml file.
Problem
E.g. the customer_app has a dependency to the model_app.
Now we add this new class in model_app such as class MyModel.
Later in the process we want to use MyModel inside of the customer_app.
If we type something like MyModel() and try to press Alt+Enter it doesn't find the class immediately. (it works miracously only sometimes)
What we have to do then is to copy the path of MyModel and do the import manually. Which is often time consuming.
We even tried to run flutter packages get which also doesn't help to find this import of MyModel. Ideally we want that Intellij find the import automatically by indexing it without copying the path out of the other project.
This is a known issue and planned to be fixed eventually.

I have this in my script
import groovy.io.FileType
.....
derp = new File("blah")
The script works but inetillij complains it cant resolve "File" and it suggested I import a totally different wrong library for it (com.jidesoft.icons.IconSet)
I already tried invalidating cache and restarting
How do I get intelllij to import groovy.io.FileType? I cant even find a way to suppress error either it doesnt give me that option
groovy.io.FileType is an enum class. It appears your variable derp would be of type File, not FileType.
You can statically import enums from the FileType class (for example):
import static groovy.io.FileType.*
In my Intellij on Java 8 the File class comes from the java.io package in a .groovy file.
I have created a listener class in my project. Now what I have read in web there are two methods to add a listener either to your class or to testng file.
Please check in the folder structure. For now, I m using it like this in my java class but it is giving me error as in image attached:
#Listeners({Test.tes.Utils.ListenerUse.class})
From your screenshots, I understand that your test class HomeTestCases.java resides in the package Test.test.MyHomepageTestCases in src/test/java
You are trying to refer to the listener ListenerToUse.java that resides in the package Test.tes.Utilsin src/main/java.
When you use #Listeners(Test.tes.MyHomepageTestCases.MyHomepageTestCases.ListenerToUse.class)
Here you are basically telling Java to look for the listener class ListenerToUse inside Test.tes.MyHomepageTestCases.MyHomepageTestCases (as a nested class), but that's not the case because ListenerToUse is NOT a embedded class inside MyHomepageTestCases.java.
To fix the problem please do the following:
Change: #Listeners(Test.tes.MyHomepageTestCases.MyHomepageTestCases.ListenerToUse.class)
To: #Listeners(Test.tes.Utils.ListenerToUse.class)
I think the issue is you're mixing the package of your Listener, and the package of the class where you want to add it.
Your code now:
#Listeners(Test.tes.MyHomePageTestCases.MyHomePageTestCases.ListenerUse.class)
Correct package:
#Listeners(Test.tes.Utils.ListenerUse.class)
However, you've named your package "Test", which is (besides breaking Java naming conventions -> https://docs.oracle.com/javase/tutorial/java/package/namingpkgs.html) clashing with the TestNG Test class. On your screenshot, I can see that "Test" is grayed out. If you hover with your mouse over it, you'll probably see Eclipse has resolved it as "org.testng.annotations.Test". So you have two options:
Name your packages properly and try again
Expand the imports sections of your HomeTestCases class; manually add:
import Test.tes.Utils.ListenerUse;
and delete the following:
import org.testng.annotations.Test;
I just installed rxjs 5 beta 3 via npm i rxjs#5.0.0-beta.3.
I have the following example code:
import {Observable} from "rxjs"
new Observable(o => o.next(42)).filter(() => true);
This code compiles perfectly well when using ts-node for example.
But when looking at this code inside IntelliJ IDEA, the filter() operator is not found.
When using operators on an Observable instance, they are not found either.
The suggested static members of Observable are:
create()
if()
throw()
The suggested members of an instance of Observable are:
_isScalar()
forEach()
lift()
subscribe()
I also tried to import only what I need, but still my IDE tells me that filter() does not exist on the Observable instance:
import {Observable} from "rxjs/Observable"
import "rxjs/add/operator/filter"
new Observable(o => o.next(42)).filter(() => true);
Any suggestions how to make IntelliJ IDEA know about the operators?
To fix this issue you need to add RxJS as a javascript library in IntelliJ:
Go to Settings -> Languages and frameworks -> JavaScript -> Libraries
Click Add...
Add node_modules/rxjs by clicking the + button
Click all the OK buttons until you are back in your editor.
This solution is tested to work on IDEA 2016.1.3
Please, check IDEA 2016.1.2 or higher
Note: Directory node_modules must be not excluded from the project.
Otherwise, see answer https://stackoverflow.com/a/38499577/1057218
Note 2: File package.json must contain the direct dependency (or devdependency) 'rxjs'
Accepted answer doesn't work. I have tested IntelliJ IDEA 2016.2.1 EAP (ideaIU-162.1447.7) and the problem still persist.
The rabbit hole goes as follows:
In the accepted answer you find a link to version 2016.1, but that doesn't fix the problem.
Then you see a comment with a link to the IntelliJ bugtracker, where OP has the first/top comment.
At the bottom of that issue/bug thread you find a comment saying IDEA 2016.2 162.426.1 EAP will definitely fix the problem, it doesn't.
Bottom line, if you import all of what RxJS has to offer with import {Observable} from 'rxjs/Rx'; IntelliJ will still complain that it can't find methods like .map and .filter
