issue: https://youtrack.jetbrains.com/issue/KT-10847

Kohesive library and Jackson module releases: (this pos will be edited as different libraries are released) Injekt is available in bintray as release

1.12.0-RC-1017

Klutter

0.13-RC-1017

Jackson Kotlin Module

2.5.5-RC-1017

,

2.6.5-RC-1017

and

2.7.0-RC-1017

Kovert

0.10-RC-1017

For any of these you need this repo added to your build until we are allowed to publish on maven central:

repositories {
    maven {
        url  "<http://dl.bintray.com/jaysonminard/kohesive>" 
    }
}

And for: Kovenant library, version

3.0.0-rc.01017

with this repo:

repositories {
    maven {
        url  "<http://dl.bintray.com/mplatvoet/komponents>" 
    }
}

I think dokka 0.9.5 being in a gradle build is breaking the compiler 1017

it causes class cast exceptions

need a new dokka

Also stdlib functions are generating this same warning, for example this code:

private val people = hashMapOf(*listOf(
            Person(1, "Frank", 30),
            Person(2, "Domingo", 19),
            Person(3, "Mariana", 22),
            Person(4, "Lucia", 31)
    ).map { it.id to it }.toTypedArray())

Warning:(169, 27) Kotlin: It may be not safe to use 'kotlin.Pair<kotlin.Int, uy.kohesive.kovert.vertx.boot.test.Person>' as an argument for a reified type parameter. Use a non-generic type or * if possible

I added this to https://youtrack.jetbrains.com/issue/KT-10847

I know that is odd code, its from like 1940 Kotlin. (the year). When modernized to this, no warning: It is

toTypedArray()

causing it on many things. And I know this is odd code because when modernized to the following, no warning:

private val people = listOf(
            Person(1, "Frank", 30),
            Person(2, "Domingo", 19),
            Person(3, "Mariana", 22),
            Person(4, "Lucia", 31)
    ).associateByTo(HashMap()) { it.id }

but this makes the warning:

val x = listOf(1,2,3).map { it to it * 4 }.toTypedArray()

just curious, how exactly

forEach

issue was fixed?

because there is exactly the same issue with

Comparator.reversed()

method

which isn’t fixed in EAP

What's the issue with

Comparator.reversed

? Either with member or with extension you get the reversed comparator.

what is “the issue"

fun main(args: Array<String>) {
  arrayListOf("hello", "world").forEach {
    println(it)
  }

  String.CASE_INSENSITIVE_ORDER.reversed()
}

compiles to

}

in case of

forEach

call extension method takes precedence over instance method, but in case of

reversed

the instance method is used

causing a crash on android, because there is no

java/util/Comparator.reversed

method in java 6

Isn't it solved by compiling against JDK7 for Android?

we are not compiling android applications against

JDK7

or

JDK8

android gradle plugin provides a bootclasspath which should be used to compile against

and it looks like kotlin compiler doesn’t respect it

AFAIK, it was solved in https://youtrack.jetbrains.com/issue/KT-10479. Or it isn't? If not, feel free to reopen, or file a new issue.

it used to be fixed, but I’m not sure why it crashes again

@ilya.gorbunov: looks like

kapt

is the one to blame

I will investigate further and will create an issue with detailed explanation

@ilya.gorbunov: here is an example that shows how to reproduce the bug https://github.com/nsk-mironov/kotlin-kapt-bug. Two identical applications, both of them are using

Comparator.reversed

method.

sample-good

works fines,

sample-bad

crashes with

java.lang.NoSuchMethodError: No interface method reversed()Ljava/util/Comparator

. The only difference between these two apps is that

sample-bad

uses

kapt

and

sample-good

doesn't.

hello every, when I change kotlin to 1.0.0-rc-101, gradle sync failed, error message is Error:Could not find org.jetbrains.kotlinkotlin gradle plugin1.0.0-rc-1017

I've add maven { url "https://dl.bintray.com/kotlin/kotlin-eap/" }

buildscript { ext.kotlin_version = '1.0.0-rc-1017​' ext.anko_version = '0.8.2rc' repositories { jcenter() maven { url "https://bintray.com/kotlin/kotlin-eap/" } } dependencies { classpath 'com.android.tools.buildG1.3.0' classpath 'com.jfrog.bintray.gradlegradle bintray plugin1.5' classpath 'com.github.dcendentsandroid maven gradle plugin1.3' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } }

I have fix the problem

after change to eap, my project compile failed

public fun <T> bindProperty(key: String, getter: () -> T): ReadWriteProperty<Any, T> public fun <T> bindProperty(key: String, vararg dependsOn: String, getter: () -> T): ReadOnlyProperty<Any, T> var name: String = bindPropery("name") { "benny" } this can not compile

I think you're missing
