java - 安卓工作室 : Could not get unknown property 'kotlin_version'

Question

从here git 克隆后,
我第一次遇到这个错误:

1: Task failed with an exception.
-----------
* Where:
Build file 'C:\...\voicegym\app\build.gradle' line: 3

* What went wrong:
A problem occurred evaluating project ':app'.
> Could not initialize class org.jetbrains.kotlin.gradle.internal.KotlinSourceSetProviderImplKt

关注 this advice ，我将这些添加到 build.gradle (Project: voicegym)

buildscript {
    ext.kotlinVersion = '1.3.72' // previously  '1.2.60'
    ext.springBootVersion = '2.0.4.RELEASE'
    ext.anko_version='0.10.4'
    repositories {
        ...
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

现在，我有这个错误

Build file 'C:\...\voicegym\build.gradle' line: 5

A problem occurred evaluating root project 'voicegym'.
> Could not get unknown property 'kotlin_version' for object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

Answer 1

实验后应该是ext.kotlin_version=...而不是 ext.kotlinVersion =...

buildscript {
    ext.kotlin_version= '1.3.72' // previously  '1.2.60'
    ext.springBootVersion = '2.0.4.RELEASE'
    ext.anko_version='0.10.4'
    repositories {
        ...
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}
