kotlinlang #announcements

@Andreas Sinz So you're assuming the article is ground truth for how the language is supposed to work, and I'd have to file a bug with the plugin?

Hi guys, what's the kotlin equivalent to java's single & conjunction?

Hey everyone, as I was writing a javadoc that

@link

a kotlin class, I noticed that the link was not being rendered in the documentation pop-over (ctrl + J)

menegatti

11/14/2016, 10:04 AM

is that expected?

@menegatti Looks like, https://youtrack.jetbrains.com/issue/KT-8503 Are link highlighted as resolved?

Looks like similar cases, you can vote for it.

is there going to be kotlin support for the new parameter name feature in the new IJ anytime soon?

I'm using simple framework for xml parsing so I needed to perform some Java-related hack. Is it possible to aggregate these two annotations with use-site targets into one?

Copy code

@field:Element(name = "name", required = false)
@param:Element(name = "name, required = false)
var element: String? = null)

what I want to achieve is:

Copy code

@fieldAndParam:Element(name = "name", required = false)
var element: String? = null)
// or at least
@XmlElement(name = "name", required = false)
var element: String? = null)

If you are looking to write a singleton to implement an interface, then you can just declare declare top-level

object

elizarov

11/15/2016, 7:32 AM

If you looking to write an object that has access to some other class private properties, then you can make them

internal

elizarov

What's your particular use-case?

stepango

In my case top level object fits perfectly, thanks. Just don't like to keep additional logic in data classes, in my case - factory methods

Any advice on how to debug and report

error.NonExistentClass

compiler errors? I'm getting this error multiple times (a few dozen) per day and it's really annoying. The problem is the error happens just randomly and disappears the next time I build the project. I've spent last few weeks looking for a reproducible scenario, but without any success.

I’m 100% sure it has something to do with kapt and incremental compilation, but I don’t know how to debug it.

@vmironov What are you using for incremental compilation ?

OK, gradle/kotlin question - I have a Kotlin module that depends on Java 8. Setting sourceCompatibility in gradle doesn't seem to work, wisdom found on stackoverflow suggest that this is because sourceCompatibility is checked by the java plugin when a compileJava task is run, which makes sense. However this module doesn't have any Java in it. So, I guess the JDK version is never checked.

mikehearn

Is this a missing feature in the Kotlin gradle plugin? Does it need an equivalent or is there a better way to test the JDK version in gradle?

christophsturm

11/15/2016, 12:02 PM

why do you need to set the java version when you don’t have java code? you can just use a 1.8 jdk to run gradle

christophsturm

11/15/2016, 12:05 PM

@mikehearn also you can just check the java version

Copy code

if(JavaVersion.current() != JavaVersion.VERSION_1_8){
    throw new GradleException("This build must be run with java 8")
}
