anyone can help me out troubleshoot this? I have a valid gradle script as far as i can tell

thank you!

Does anybody know if refactoring

use interface where possible

works for kotlin?

In Android Studio, I have two directories java/ and kotlin/. When I <Convert Java File to Kotlin> and then move the file from the java package to the kotlin package, after restarting AS the .kt file exists twice in both directories and is marked as green (so added to git). I had another issue where suddenly a whole new directory I created in another branch was suddenly added as new files (also green as in added to git) into my current branch without ever merging. I only used the “Checkout branch” function from AS. It only ever happened with Kotlin files but from the second incident I would assume it has something to do with the Git plugin. Has anyone had similar issues?

so, i'm seeing this... warning in intellij on some variables in my spek tests, and i can't even parse the sentence let alone grok what it means:

Wrapped into a reference object to be modified when captured in a closure

everything works fine, but... that's seems like a "less than useful" message

Can you show the code?

In Java, variables that are modified in anonymous functions/lambdas need to be final, so often times you put them into arrays so you can change the reference. You don’t need to do that in Kotlin because it’s internal, so I assume this warning could be related to that

This is just a soft warning to make sure you understand what's happening, which is what Allan wrote.

When I run

mvn dependency:tree

there is not a single kotlin related thing that would not be

1.2.51

.

I have been getting the same warning for weeks now. Just updated to 2018.2 and the warning still shows up. Fix your sh*t JetBrains.

just an observation, wouldn't make sense to also have a gradle refresh for gradle-based project whenever you pull and the

build.gradle

has been modified?

Hrm.. there's a flaw with updating intellij. It's using 2018.1's intellij path for kotlin sdk presumably because when I updated to 2018.2 it asked if i wanted to copy configuration from 2018.1

I wish there was a refactoring from singleton to a class with an empty constructor

object MyClass { ... }

to

MyClass() { .. }

It's a bit painfull to replace manually all

(e == MyClass)

to

(e is MyClass)

and all

doSomething(MyClass)

to

doSomething(MyClass())

doubtful it would get prioritized. you could probably emulate it with structural search and replace

Wait, does

Search structurally

now exist for Kotlin?

It doesn't, at least in Android Studio 3.1.3

No it doesn't exist yet, here's the issue: https://youtrack.jetbrains.com/issue/KT-10176

It's been open for 3 years with priority Major, great.

Anyone knows why I would be getting an XML shown instead of the test results after running tests? Code under test is in Kotlin, tests run with Spock, XML looks like

<ijLog><event type='afterSuite'><ijLogEol/>
  <test id='1.72' parentId='1.1'><ijLogEol/>
    <descriptor name='my.class.name' className='my.class.name' /><ijLogEol/>
    <result resultType='SUCCESS' startTime='1533899133943' endTime='1533899133952'><ijLogEol/>
      <failureType>error</failureType><ijLogEol/>
    </result><ijLogEol/>
  </test><ijLogEol/>
</event></ijLog>

I recently upgraded IDEA to 2018.2

..it seems to work with IDEA JUnit runner, but then all tests fail horribly 😞

Since when is

private fun foo() = TODO()

an IDE error?

'Nothing' return type needs to be specified explicitly.

It's a compilation error too.

Actually good advice to specify return type to avoid confusion with inferred Nothing

I don't really get that, it can be obvious that it returns

Nothing

just like can be obvious for other types.
