错误：找不到com.android.tools.build:gradle:3.3。升级splunk的gradle版本后出现问题：mint-android-sdk

Question

我的应用程序运行良好，然后我添加了com.splunk：mint-android-sdk，这需要gradle的更高版本，因此我将gradle从2.1升级到了3.3。之后，我面临问题。请查看我的gradle文件并为我提供帮助，并指导我它的工作方式。（这是我的第一个应用程序，但我想确保其在所有情况下都可以正常工作）

Answer 1

在buildscript内添加google（），然后打开终端写入命令-gradlew build并按Enter。

repositories {
    google()
    jcenter()
}

Answer 2

您更改了Gradle插件版本，而不是Gradle版本

将您的Gradle插件版本设置为2.3，
然后在行中打开gradle/wrapper/gradle-wrapper.properties并更改Gradle版本distributionUrl

Answer 3

此版本的gradle 插件不存在。

classpath 'com.android.tools.build:gradle:3.3'

使用最新的测试版：

classpath 'com.android.tools.build:gradle:3.0.0-beta6'

相反，如果您想更新 gradle，请更新distributionUrlin gradle-wrapper.properties。
