android - Gradle 构建完成，但出现错误

Question

我正在尝试在 Android Studio 中运行之前在 Eclipse 中运行的项目，但是 gradle 插件让我遇到了困难，首先它说 Gradle 版本不受支持，然后我修改了 build.gradle，现在当我尝试在末尾运行它，显示 Gradle finish with 1 error，这是 gradle-wrapper.properties:

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=http\://services.gradle.org/distributions/gradle-2.2.1-   all.zip

这是build.gradle:

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

apply plugin: 'android'

dependencies {
compile fileTree(dir: 'libs', include: '*.jar')
compile 'com.android.support:appcompat-v7:19.1.0'
}

android {
compileSdkVersion 19
buildToolsVersion "22.0.1"

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

    instrumentTest.setRoot('tests')

    debug.setRoot('build-types/debug')
    release.setRoot('build-types/release')
}
}

这是消息日志:

感谢您的回复。我最终通过删除这一行解决了问题:

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