使用Gradle构建Android

Question

我仍然收到错误

“评估项目'：app'时发生问题。

需要Gradle 1.10版。 当前版本是1.12。 如果使用gradle包装器，请尝试将D：\\ AndroidStudioWorkspace \\ HelloGradl e \\ gradle \\ wrapper \\ gradle-wrapper.properties中的distributionUrl编辑为gradle-1.10-all.zip“

虽然我更新了build.gradle如下：

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:0.10.+'
    }
}

apply plugin: 'android'

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.3"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

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

我通过创建一个新的工作区并在其中创建一个新项目来做到这一点。

然后执行File> Export> Generate Gradle构建文件。

一旦生成build.gradle文件，如下所示：

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.10.+'
    }
}
apply plugin: 'android'

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
}

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.3"

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        // Move the tests to tests/java, tests/res, etc...
        instrumentTest.setRoot('tests')

        // Move the build types to build-types/<type>
        // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
        // This moves them out of them default location under src/<type>/... which would
        // conflict with src/ being used by the main source set.
        // Adding new build types or product flavors should be accompanied
        // by a similar customization.
        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }
}

转到命令提示符，转到项目目录并运行命令：gradle build

而已！ U将看到以下输出：

打开以下文件： project_root/gradle/wrapper/gradle-wrapper.properties 。

确保distributionUrl设置为1.10 ：

distributionUrl=http\://services.gradle.org/distributions/gradle-1.10-all.zip
