错误：org.gradle.internal.UncheckedException：构建命令失败

Question

我试图扩展this project，但它是使用ANT构建的，现在我们在实践中使用Android Studio和Gradle。我想在Android Studio上进一步实现它。因此，这里是我的项目结构...

应用/的build.gradle

apply plugin: 'com.android.application' 
android { 
    compileSdkVersion 25 
    buildToolsVersion "26.0.0" 
    defaultConfig { 
     applicationId "tum.andrive" 
     minSdkVersion 14 
     targetSdkVersion 25 
     versionCode 1 
     versionName "1.0" 
     ndk { 
      abiFilters "armeabi", "armeabi-v7a" 
     } 
     sourceSets { 
      main { 
       jniLibs.srcDirs = ['src/main/cpp'] 
      } 
     } 
     externalNativeBuild { 
      cmake { 
       cppFlags "-frtti -fexceptions" 
      } 
     } 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
    externalNativeBuild { 
     cmake { 
      path "CMakeLists.txt" 
     } 
    } 
} 

dependencies { 
    compile fileTree(include: ['*.jar'], dir: 'libs') 
    compile 'com.android.support:appcompat-v7:25.3.1' 
    compile project(':opencv') 
} 

的CMakeLists.txt

但是，得到错误，而建设项目，对这个一看...

有人请帮我设置这个项目！

Answer 1

经过大量的搜索，我发现this项目。非常感谢Adrien Lescourt。这个演示项目描述了我们如何使用OpenCV与Android Studio & Gradle。问题在于jniLibs目录和CMakeLists.txt文件。下面是正确的版本...

应用/的build.gradle

apply plugin: 'com.android.application' 
android { 
    compileSdkVersion 25 
    buildToolsVersion "26.0.0" 
    defaultConfig { 
     applicationId "tum.andrive" 
     minSdkVersion 14 
     targetSdkVersion 19 
     versionCode 1 
     versionName "1.0" 
     ndk { 
      abiFilters "armeabi-v7a" 
     } 
     sourceSets { 
      main { 
       jniLibs.srcDirs = ['src/main/jniLibs'] 
      } 
     } 
     externalNativeBuild { 
      cmake { 
       cppFlags "-frtti -fexceptions" 
       abiFilters 'x86', 'x86_64', 'armeabi', 'armeabi-v7a', 'arm64-v8a', 'mips', 'mips64' 
      } 
     } 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
    externalNativeBuild { 
     cmake { 
      path "CMakeLists.txt" 
     } 
    } 
} 

dependencies { 
    compile fileTree(include: ['*.jar'], dir: 'libs') 
    compile 'com.android.support:appcompat-v7:25.3.1' 
    compile project(':opencv') 
} 

的CMakeLists.txt

cmake_minimum_required(VERSION 3.4.1) 

# OpenCV stuff 
include_directories(D:\\Android\\OpenCV-2.4.10-android-sdk\\sdk\\native\\jni\\include) 
add_library(lib_opencv SHARED IMPORTED) 
set_target_properties(lib_opencv PROPERTIES IMPORTED_LOCATION ${CMAKE_CURRENT_SOURCE_DIR}/src/main/jniLibs/${ANDROID_ABI}/libopencv_java.so) 

add_library(native-lib    
      SHARED       
      src/main/cpp/native-lib.cpp) 

find_library(log-lib 
       log) 

target_link_libraries(native-lib      
         lib_opencv 
         ${log-lib}) 

，最后我添加jniLibs文件夹的应用程序，并复制全部.so此文件夹中的文件存储在OpenCV-2.4.10-android-sdk/sdk/native/libs。

我希望这个解决方案将帮助人们建立OpenCV的与gradle这个。如果需要其他信息，请发表评论。

谢谢
