android - 找不到与 com.android.support :support-v7:20. 0.+ 匹配的任何版本

Question

我是安卓开发的新手我写过

classpath 'com.android.tools.build:gradle:1.0.0+'

runproduard() is replaced with minifyenabled. The result : Build successful

但是在运行时出现了这个错误:

我的代码是:

compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.+'
compile 'com.android.support:support-v4:21.0.+'

但是 698 条警告，因为找不到在 libs 文件夹中添加的引用类 xom

Error:Execution failed for task ':app:proguardMobifoodDemoDebug'. java.io.IOException: Please correct the above warnings first.

我的android studio版本是1.0.2，gradle版本是2.2.1

Answer 1

模块目录下的build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.+'
    compile 'com.android.support:support-v4:21.0.+'
}

“+”允许 gradle 自动升级到 jar 的最新错误修复版本。

最外层工程目录下的build.gradle

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.0'

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

allprojects {
    repositories {
        jcenter()
    }
}
