Question

所以我正在尝试将JavaCV与Android Studio一起使用。我正在尝试使用FaceRecognizer类的包装器。我试过让这段代码运行几个小时但到目前为止没有运气。我不断收到构建错误：

     Error:A problem occurred configuring project ':app'.
     > Could not find javacpp-presets-Mac OS X-x86_64.jar
      (org.bytedeco:javacpp-presets:1.2).
      Searched in the following locations:
      https://jcenter.bintray.com/org/bytedeco/javacpppresets/1.2/javacpp-presets-1.2-Mac OS X-x86_64.jar'

我解压缩了opencv的.so文件并拆分成两个文件：armeabi和x86，所以没关系。

这是我的build.gradle文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"
    sourceSets.main.jni.srcDirs = []

    //task ndkBuild(type: Exec, description: 'Compile JNI source via NDK') {
    //    ndkDir = project.plugins.findPlugin('com.android.application').sdkHandler.getNdkFolder()
    //    //on Windows, you need to add ".cmd" after "ndk-build" below
    //    commandLine "$ndkDir/ndk-build",
    //            'NDK_PROJECT_PATH=build/intermediates/ndk',
    //            'NDK_LIBS_OUT=src/main/jniLibs',
    //            'APP_BUILD_SCRIPT=src/main/jniLibs/Android.mk',
    //            'NDK_APPLICATION_MK=src/main/jniLibs/Application.mk'
    //}
    //task ndkLibsToJar(type: Zip, dependsOn: 'ndkBuild', description: 'Create a JAR of the native libs') {
    //    destinationDir new File(buildDir, 'libs')
    //    baseName 'ndk-libs'
    //    extension 'jar'
    //    from(new File(buildDir, 'libs')) { include '**/*.so' }
    //    into 'lib/'
    //}
    //tasks.withType(JavaCompile) {
    //    compileTask -> compileTask.dependsOn ndkBuild
    //}

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}
    dependencies {
        compile fileTree(include: ['*.jar'], dir: 'libs')
        compile fileTree(dir: new File(buildDir, 'libs'), include: '*.jar')

        compile 'org.bytedeco:javacv:1.2'
        compile 'org.bytedeco.javacpp-presets:opencv:3.0.0-1.1:android-x86'
        compile 'org.bytedeco.javacpp-presets:opencv:3.0.0-1.1:android-arm'
        //compile group: 'org.bytedeco', name: 'javacv', version: '1.2'

        //compile group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '2.4.10-0.10', classifier: 'android-arm'
        //compile group: 'org.bytedeco.javacpp-presets', name: 'ffmpeg', version: '2.5.1-0.10', classifier: 'android-arm'

    }

我不知道如何从这里开始。我需要对build.gradle进行哪些修改才能进行编译？我尝试使用javacv 1.1但是我在运行时遇到错误，而.so文件都来自javacv 1.2。

我有类似的问题。 Gradle的依赖解析显然存在一个错误。 Javacpp的作者已经提供了一种解决方法，请参见此处：https://github.com/bytedeco/javacv/issues/432

尝试在build.gradle脚本中包含以下代码：

configurations {
    all*.exclude group: 'org.bytedeco', module: 'javacpp-presets'
}

它对我有用，希望能帮到你。
