Is there a minimum gradle version for kotlin 1.3?

[ribesg]

Depends what you’re talking about. If you just compile kotlin, I don’t think so. If you’re using Gradle kotlin-dsl, then yes

[hudsonb]

When I change ext.kotlin_version = '1.2.50' to 1.3.0, I get the following when it tries to apply the kotlin plugin:

A problem occurred evaluating root project 'kubed'.
> Failed to apply plugin [id 'kotlin']
   > Could not generate a proxy class for class org.jetbrains.kotlin.gradle.dsl.KotlinJvmProjectExtension.

[ribesg]

Are you using JDK8?

[hudsonb]

Yep

[hudsonb]

Upgrading gradle for this project is fine, been meaning to add a gradle wrapper to it forever. Just have some work stuff that requires gradle 2 right now so 2 is on the path and 1.3.0 doesn't seem to like it

[ribesg]

This error has a cause, try to print it with --stacktrace

[hudsonb]

groovy.lang.MissingPropertyException: Could not get unknown property 'kotlin_version' for object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

[ribesg]

It does not find your ext.kotlin_version

[hudsonb]

Sorry I was messing around see what was wrong, added that back in the error is:

java.lang.NoClassDefFoundError: org/gradle/api/attributes/HasAttributes

[hudsonb]

Which I assume was added to gradle in a version newer than the one Im using

[ribesg]

Pretty sure this means Gradle upgrade required

[hudsonb]

Agreed, thanks

[ribesg]

This one thing was added in 3.3

[ribesg]

So unless it’s something else that you upgraded that requires that, we now know that the answer to your original question was that yes, Kotlin 1.3 requires Gradle 3.3+

In most cases better to use the latest stable Gradle
