hmm, when i compiling , it gives me

Error:Kotlin: Runtime JAR file has version 1.0 which is older than required for language version 1.1

error.

see "Source compatibiliy with Kotlin 1.0" section under https://blog.jetbrains.com/kotlin/2017/02/kotlin-1-1-beta-2-is-here/

oh, i see. Thanks!

i've set the kotlin version to

1.0

in IDEA configuration, but

allopen

and

noarg

plugins seems doesn't work

i tried to set the Kotlin facet settings, then gives me

Error:Kotlin: [Internal Error] java.lang.NoClassDefFoundError: org/jetbrains/kotlin/resolve/DeclarationChecker

error

I think you need a three-digit version.

1.0.6

is the current one.

its not available in options

^ @yan

only

1.0

and

1.1

i can choose

@Sola What build system do you use?

maven, but it works very fine when just using command line

mvn compile

the problem i got is building with IDEA(ctrl+F9)

What’s the version of the

all-open

plugin in Maven POM?

its

${kotlin.version}

, (1.0.6)

Well, if your plugin version inside IDEA is 1.1, the compiler plugin also should be

1.1

as it uses the compiler internal API that changed from 1.0.x.

oh, okay, what about

stdlib

version?

If the language mode is set to 1.0, 1.0.6 should be ok

i see, if so, i think its almost upgraded to 1.1, simple smile

after i upgraded to

1.1

, the

allopen

and

noarg

plugins still doesn't work 😞

@Sola I’ll investigate this shortly. Can you please file an issue for this?

okay, I'm gonna make a test project.

when i'm creating test project, i realized the kotlin idea plugin adding

kotlin-stdlib-jre8

dependency instead of

kotlin-stdlib

, so i just changed my

POM.xml

to using

kotlin-stdlib-jre8

, it works fine now. 🙂

What is

kotlin-stdlib-jre8

?

kotlin-stdlib

with java 8 bytecode ?

some java8 specific things like support of AutoClosable

Ok thanks

So I guess that will make sense to use that with Spring Framework (will be Kotlin 1.1 and Java 8+ based)

Sorry, i double checked, and AutoCloseable part of jre7, jre8 contains Sequence <-> Stream extensions

My opinion that libraries should use compileOnly() for kotlin libraries

I'm trying out 1.1 beta2. I'm developing an IDEA plugin and so the library with all IDEA classes has an 1.0 version of Kotlin in it. This is now an error when compiling unless I pass

-Xskip-runtime-version-check

to the compiler. In gradle I can write

compileKotlin.kotlinOptions.freeCompilerArgs = ['-Xskip-runtime-version-check']

and it works, but the gradle project import does not pick up this argument. I can manually add it to the Kotlin facet but it is gone after each new project import. Is there a way to get persistent command line options for the compiler?
