找不到java Android Studio生成渐变

Question

我有一个Android Studio项目，这是build.gradle文件：

buildscript {
ext.kotlin_version = "1.1.3"
repositories {
    jcenter()
    google()
}
dependencies {
    classpath 'com.安卓.tools.build:gradle:3.0.0'
    classpath 'com.google.gms:google-services:3.0.0'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath "org.jetbrains.kotlin:kotlin-安卓-extensions:$kotlin_version"
}

}

当我尝试构建应用程序时，出现以下错误：

Gradle sync failed: Could not find gradle.jar (com.安卓.tools.build:gradle:3.0.0).
Searched in the following locations:
https://jcenter.bintray.com/com/安卓/tools/build/gradle/3.0.0/gradle-3.0.0.jar
Consult IDE log for more details (Help | Show Log) (899 ms)

Answer 2

Gradle sync failed: Could not find gradle.jar (com.android.tools.build:gradle:3.0.0).

您应该升级tools.build:gradle版本

 classpath 'com.android.tools.build:gradle:3.4.2'
 classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.31"
 classpath 'com.google.gms:google-services:4.3.2'

而gradle-wrapper将

distributionUrl=https\://services.gradle.org/distributions/gradle-5.1.1-all.zip //5.4.1

之后，Clean->Rebuild-> Gradle
