Gradle 빌드 중 설치된 NDK를 인식하지 못하는 현상

UnityHub가 도입되고 고도화되면서 Unity 설치 시에 각 플랫폼 별 빌드 지원하는 툴들을 설치하게 되었다.

그 후로는 유사한 이슈가 발생하지 않았는데 2021.3.22f1버전에서 2022.3.6f1버전으로 업그레이드 하면서 발생했다.

    public class AndroidPostBuildProcessor : IPostGenerateGradleAndroidProject
    {
        public int callbackOrder => 1;

        public void OnPostGenerateGradleAndroidProject(string path)
        {
            Debug.Log("OnPostGenerateGradleAndroidProject: " + path);

            var di = new DirectoryInfo(path);
            var localPropertiesFile = Path.Combine(di.Parent.FullName, "local.properties");
            if (File.Exists(localPropertiesFile))
            {
                var hasNdkProp = HasNdkProp(localPropertiesFile);
                if (false == hasNdkProp)
                {
                    var ndkDir = $"{System.Environment.NewLine}ndk.dir={AndroidExternalToolsSettings.ndkRootPath}";
                    File.AppendAllText(localPropertiesFile, ndkDir);
                }
            }
        }

        private bool HasNdkProp(string path)
        {
            using (var streamReader = new StreamReader(path, System.Text.Encoding.UTF8))
            {
                string line = string.Empty;
                while ((line = streamReader.ReadLine()) != null)
                {
                    if (line.StartsWith("ndk.dir="))
                        return true;                    
                }
            }
            return false;
        }
    }
#endif
}

근본적인 해결책은 아니지만 
Android Project를 생성할 때, local.properties 파일에 NDK 정보를 입력하는 식으로 해결하였다.
