如何更新com.android.application插件？

Question

我收到这条消息:

Plugin is too old, please update to a more recent version,
or set ANDROID_DAILY_OVERRIDE environment variable to
"a9d6c794295e89d95704157e2ed8fd55ffd2765c"

和:

C:\path\mobile\build.gradle
Error:(1) A problem occurred evaluating project ':mobile'.
Failed to apply plugin [id 'com.android.application']
Could not create plugin of type 'AppPlugin'.

top build.gradel文件:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.0-beta1'
        classpath 'com.google.gms:google-services:1.3.0-beta1'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

基本上,我不知道如何更新该com.android.application插件.

Answer 1

我只需要换行

classpath 'com.android.tools.build:gradle:2.0.0-alpha1'

至

classpath 'com.android.tools.build:gradle:2.0.0-alpha3'在顶部 build.gradle

我知道这是alpha3因为上一篇发行说明http://tools.android.com/tech-docs/new-build-system.

Answer 2

显然,Gradle for Android插件的测试版将过期.AFAIK,没有记录的行为.现在,通过监控http://tools.android.com/tech-docs/new-build-system,我知道了解最新测试版本的唯一方法.它实际上显示了一个beta3; 我以为最新的是beta2.
