google-cloud-vision - 谷歌视觉 API：java.lang.NoClassDefFoundError：com/google/cloud/vision/v1/ImageAnnotatorClient 错误

Question

我正在尝试运行 Google Api Vision 示例代码，但出现此错误：

java.lang.NoClassDefFoundError:com/google/cloud/vision/v1/ImageAnnotatorClient

这些是导入到我的项目中的依赖项。

使用包Google.Cloud.Vision.V1或者您可能还想根据您的框架检查要使用的正确客户端库。
