java - 为什么gradle会出错？

Question

我尝试在我的项目中导入 OpenCV 模块。我找到了一些不错的教程并创建了新项目来测试 OpenCV 实现。问题，当我在新项目中导入 OpenCV 库时一切正常(教程 here )。

但是当我对现有项目进行相同的操作时，我收到了错误

我尝试修复它，但没有成功。我该如何修复它？

Gradle 文件

buildscript {
    repositories {
        jcenter()
    }

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

apply plugin: 'com.android.application'

repositories {
    jcenter()
}

dependencies {
    compile 'com.android.support:support-v4:23.2.0'
    compile 'com.android.support:support-v13:23.2.0'
    compile 'com.android.support:cardview-v7:23.2.0'
    compile 'com.android.support:appcompat-v7:23.2.0'
    compile files('libs/svgandroid.jar')
    compile files('libs/svg-android.jar')
    compile files('libs/guava-16.0.1.jar')
}

// The sample build uses multiple directories to
// keep boilerplate and common code separate from
// the main sample code.
List<String> dirs = [
    'main',     // main sample code; look here for the interesting stuff.
    'common',   // components that are reused by multiple samples
    'template' // boilerplate code that is generated by the sample  template process
]

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        minSdkVersion 22
        targetSdkVersion 23
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }

    sourceSets {
        main {
            dirs.each { dir ->
                java.srcDirs "src/${dir}/java"
                res.srcDirs "src/${dir}/res"
            }
        }
        androidTest.setRoot('tests')
        androidTest.java.srcDirs = ['tests/src']
    }
}

最新 Gradle:2.11

检查:gradle -v

在这里下载:http://services.gradle.org/distributions/gradle-2.11-bin.zip

最新 Android 构建工具:1.5.0

如果将以下代码 fragment 添加到 build.gradle 文件的顶部，gradle 将更新构建工具。

buildscript {
    repositories {
        jcenter() // or mavenCentral()
    }

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