distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-2.10-all.zip
https\://services.gradle.org/distributions/gradle-2.10-all.zip=

Answer 1

您需要编辑gradle/wrapper/gradle-wrapper.properties 。

将distributionUrl更改为https\\://services.gradle.org/distributions/gradle-2.14.1-all.zip

Answer 2

1. 将gradle-wrapper.properties中的distributionUrl更新为

https\\://services.gradle.org/distributions/gradle-2.10-all.zip

2. 您也可以将根目录build.gradle以及应用程序级别的build.gradle文件中的gradle构建工具更新为最新版本。 在我的情况下，它是classpath 'com.android.tools.build:gradle:2.1.2'
