我不明白gradle有什么问题？

Answer 1

在build.gradle文件中，确保您使用的是最新版本的gradle插件。目前为1.5.0

buildscript {
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'
    }
}

然后转到platforms/android/gradle/wrapper/gradle-wrapper.properties，并确保distributionUrl值使用的是最新版本。

distributionUrl=https\://services.gradle.org/distributions/gradle-2.8-all.zip

另外，我建议添加这个环境变量，这样它就可以拉出您想要的gradle包装器发行版的url版本。Cordova倾向于添加一个旧版本，除非您添加此环境变量。

CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL=http://services.gradle.org/distributions/gradle-2.8-all.zip
