android开发里跳过的坑-AS导入NDK工程提示错误 No such property: sdkHandler for class: com.android.build.gradle.LibraryPlugin

接到一个NDK工程需要调试，导入后发现总是提示错误

Error:(37, 1) A problem occurred evaluating project ':libuvccamera'.
> No such property: sdkHandler for class: com.android.build.gradle.LibraryPlugin

百度上各种说法，有说要降低gadle版本，有说要在环境变量里配置ANDROID_NDK的路径，试验了都不行，最后参考别人NDK gradle文件修改如下：

未修改之前：

task ndkBuild(type: Exec, description: 'Compile JNI source via NDK') {

   println('executing ndkBuild')

   def ndkBuildingDir = project.plugins.findPlugin('com.android.library').sdkHandler.getNdkFolder().absolutePath

   def ndkBuildPath = ndkBuildingDir

  if (Os.isFamily(Os.FAMILY_WINDOWS)){

    ndkBuildPath = ndkBuildingDir + '/ndk-build.cmd'

   } else {
    ndkBuildPath = ndkBuildingDir + '/ndk-build'
   }
   commandLine ndkBuildPath, '-j8', '-C', file('src/main').absolutePath
}

可修改为

task ndkBuild(type: Exec, description: 'Compile JNI source via NDK') {
   println('executing ndkBuild')
   def ndkBuildingDir = android.ndkDirectory
   if (Os.isFamily(Os.FAMILY_WINDOWS)) {
      ndkBuildingDir = "$ndkBuildingDir/ndk-build.cmd"
   } else {
      ndkBuildingDir = "$ndkBuildingDir/ndk-build"
   }
   commandLine ndkBuildingDir, '-j8', '-C', file('src/main').absolutePath
}

   
    println('executing ndkBuild')

            '-C', file('src/main').absolutePath, // Change src/main/jni the relative path to your jni source
            '-j', Runtime.runtime.availableProcessors(),
            'all',
            'NDK_DEBUG=1'

   }

}
