Failed to apply plugin [id 'org.jetbrains.kotlin.jvm']
223   > The current Gradle version 5.1.1 is not compatible with the Kotlin Gradle plugin. Please use Gradle 5.3 or newer, or the previous version of the Kotlin plugin.

You should use Gradle 5.3 or newer. Try Gradle 6.6

[stephanmg]

Yeah, I used now 6.6.1

[stephanmg]

but has to manually install on Travis

[jbnizet]

Travis uses the gradle wrapper automatically if it find a gradlew script in your project. You should use the wrapper. Always.

[stephanmg]

ah I see

[stephanmg]

So you are saying i should always provide the gradle wrapper in the project?

[stephanmg]

Gradle 6 has now a predefined Wrapper task?

[edrd]

Whenever you generate a Gradle project, a gradlew file will be created. It's intended to allow you to use Gradle without having to install it, and also ensures the version used is the correct one.
What Jean-Baptiste meant about using the wrapper is: ./gradlew <your-task>.
Also, since it will have to download and install Gradle, it's a good a idea to cache $GRADLE_HOME. More info here: https://guides.gradle.org/executing-gradle-builds-on-travisci/

And about the wrapper in general: https://docs.gradle.org/current/userguide/gradle_wrapper.html

[stephanmg]

Thanks. Yeah, Gradle 6 is very neat.
