标签： java heroku jdbc jhipster buildpack

我正在尝试将基于jhipster的Web应用程序部署到heroku + cleardb插件。 我的应用程序使用mysql作为数据库，并在本地工作正常。 我已经按照heroku java教程中提到的所有步骤进行了操作，但是在启动我的dynos时，我收到以下错误

我使用的是java buildpack，我的procfile如下：

  

java -jar target / * .war --spring.profiles.active = dev，heroku --server.port = 8080 --jhipster.metrics.jmx.enabled = false --spring.datasource.maximumPoolSize = 5 < / p>
