如何修复错误:(158)Android NDK:正在中止. .停止. (ndk-build.cmd''以非零退出值2结束)

我想通过使用OpenCV开发有关在扫描的图像或照片中自动裁剪的android应用程序.我在 github 上找到了一个名为"android-opencv-scan-doc"的开源应用程序.一个>.下载后，请尝试在计算机上构建并运行此项目.该应用程序无法启动，并给出以下异常:

I want to develop an android application about Auto crop in a scanned image or photo by using OpenCV. I found an open source application name "android-opencv-scan-doc" on github. After I downloaded, try to build and run this project on my computer. The application can not start and gives the following exception:

应用程序build.gradle中的

代码是:

code in app build.gradle is:

apply plugin: 'com.android.application'

    } else {

    }
}

tasks.withType(JavaCompile) {
    compileTask -> compileTask.dependsOn ndkBuild
}

clean.dependsOn 'ndkClean'
}

那我该怎么办?我不知道该如何对付他们.预先感谢.

So what should i do? I do not know how to deal with them. Thanks in advance.
