One of my projects (and only that one) is suddenly refusing to launch anything:

Error: Could not find or load main class com.beust...

Yet the class is found (since I have a valid launch configuration). Any thoughts what might be wrong with that project?

I verified all the correct classes are present in

out/production

Does anyone know if there is a way to auto populate Kdoc when typing /** in Android Studio?

@clackbib: this feature is intentionally not provided. we find that Javadoc-style documentation where every parameter and return value is explicitly documented tends to be verbose and repetitive. instead, we prefer to write documentation which mentions parameter names in natural-sounding English sentences. there’s not much use in autogeneration when this doc style is used, so we haven’t provided the autogeneration feature.

the style guide in my codebase states explicitly not to use @param or @return annotations but rather, write a single coherent paragraph

unless the docs for a param are so specific it really makes sense

@mikehearn: Is Dokka smart enough to find the parameters in your documentation and highlight them in the HTML or do they still need to be denoted (e.g.

@param

)?

can't recall. i haven't used dokka much, it seemed pretty much a work in progress last time i tried it

@cedric: parameters need to be explicitly linked

(i.e. put the parameter name in brackets)

[likeThis] ?

yep

just got bit when using the

+=

operator on a mutable set that was a

var

. Took me a while to figure out why the call was ambigious. not sure if this deserves a quick fix or at least a better error message but took me a while to figure out. for reference, this doesn't work:

var set = mutableSetOf<String>() //should be a val
set += "a"

any situation in which users get confused deserves a better error message

so please do file a YT issue

Do you think I should fill a YT issue for a quick fix notice suggesting

open

keyword for

@Configuration

,

@Component

classes and

@Bean

methods for Spring + Kotlin projects (they require non final due to proxy usage)?

That’s #1 Spring user issue with Kotlin

yes, please do

Ok

we’re starting work on IDE support for Spring right now, so you’re welcome to file issues any time you notice something working in Spring for Java but not for Kotlin

The #2 error is unlike in Java,

arrayOf

is needed for single value in array annotation attribute like

@RequestMapping("/", method = arrayOf(RequestMethod.GET))

, but this is more a Kotlin design choice I guess, so not sure there is something to do on IDE level ...

That’s a clean design decision but since we use a looooot that kind of trick in Spring API

That’s not great for us 😉

I think that the problem is on the Java side, annotation syntax is really inconsistent with other part of Java

Nice

I have created https://youtrack.jetbrains.com/issue/KT-11098

With these 2 functionalities Spring app developers will be happy 😉

@dh44t: I agree but this « trick » is used by many Java API

indeed
