This project contains a “hello world” example for the Google Cloud Vision API.
The pom.xml file runs the CloudVisionHelloWorld class, which fetches the labels of a hard-coded image.
To run this example, first make sure your GOOGLE_APPLICATION_CREDENTIALS environment variable is set and that you’ve enabled the Vision API. Then modify the filePath variable in the CloudVisionHelloWorld class and then execute this command:
mvn clean compile exec:java
