无法解决依赖关系Heroku

Question

我在Spring Boot项目中包括Junit 5。当我部署到Heroku时，无法下载具有以下错误的依赖项：

[ERROR] Failed to execute goal on project dsa: Could not resolve dependencies for project com.josephbateh:dsa:jar:0.0.1-SNAPSHOT: Failed to collect dependencies at org.springframework.boot:spring-boot-starter-test:jar:2.0.5.RELEASE -> junit:junit:jar:[5.2.0, 6.0.0): No versions available for junit:junit:jar:[5.2.0, 6.0.0) within specified range -> [Help 1]

我已经考虑使用其他存储库，但是我一定做错了，因为无论我做什么，Heroku都一直尝试使用this repository。我查看了存储库，它不包含Junit 5或Surefire插件的正确版本。

该如何解决此问题？

可以找到仓库here
