错误：任务执行失败

Question

我已从以下链接下载了一个项目。

https://github.com/DFTinc/onyx-enroll-wizard-sample-app1/tree/master/onyxenrollwizardsampleapp/src/main

Gradle Build出现以下错误。

 Error:Execution failed for task ':onyxenrollwizardsampleapp:processDebugResources'.
com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Android\sdk\build-tools\22.0.1\aapt.exe'' finished with non-zero exit value 1

此外，每个R.xxx函数都会将 R 的错误视为"cannot resolve symbol R"
