Heroku 上的 Spring Boot + 云 API 部署

[英]Spring Boot + cloud API deployment on heroku

I'm trying to deploy simple app provided by google: https://github.com/GoogleCloudPlatform/java-docs-samples/tree/master/vision/spring-framework on heroku.我正在尝试在 heroku 上部署由 google 提供的简单应用程序: https : //github.com/GoogleCloudPlatform/java-docs-samples/tree/master/vision/spring-framework

I've already done what is suggested in this thread How to use Google API credentials json on Heroku?我已经完成了此线程中的建议如何在 Heroku 上使用 Google API 凭据 json? . . But still im getting error.但我仍然收到错误。 Im not even sure if its google credentials error or something else.我什至不确定它的谷歌凭据错误还是其他什么。 Just for the record app works locally.仅用于记录应用程序在本地工作。

Here's pom.xml file i've already made some changes so its not clone of github project这是pom.xml文件,我已经进行了一些更改,因此它不是 github 项目的克隆
