在尝试构建我的 android ndk 项目时出现以下错误。安卓工作室版本 3.1.3

FAILURE：构建失败，出现异常。

• 出了什么问题：任务 ':app:ndkBuild' 执行失败。

  进程 'command'/Users/bnaskar/Library/Android/sdk/ndk-bundle/ndk-build'' 以非零退出值 2 结束

• 尝试：使用 --info 或 --debug 选项运行以获得更多日志输出。使用 --scan 运行以获得完整的见解。

• 例外是：

org.gradle.api.tasks.TaskExecutionException: 任务 ':app:ndkBuild' 执行失败。在 org.gradle.api.internal.tasks.execution.ExecuteActionsTaskExecuter.executeActions(ExecuteActionsTaskExecuter.java:100) 在 org.gradle.api.internal.tasks.execution.ExecuteActionsTaskExecuter.execute(ExecuteActionsTaskExecuter.java:70) 在 org.gradle .api.internal.tasks.execution.OutputDirectoryCreatingTaskExecuter.execute(OutputDirectoryCreatingTaskExecuter.java:51) at org.gradle.api.internal.tasks.execution.SkipUpToDateTaskExecuter.execute(SkipUpToDateTaskExecuter.java:62) at org.gradle.api. .tasks.execution.ResolveTaskOutputCachingStateExecuter.execute(ResolveTaskOutputCachingStateExecuter.java:54) 在 org.gradle.api.internal.tasks.execution.ValidatingTaskExecuter。
