Grails 3：无法推送到Heroku

Question

I was pushing the current git repository into the heroku. That online application was developed using Grails 3 and IntelliJ. And I don't know how to fix this error.

Answer 1

The errors says that your app is not compatible with Gradle buildpack. I am not familiar with Grails framework and how can you deploy it to Heroku, so I can't give you specific answer. But you should follow instructions for Gradle buildpack . Buildpack is checking for three files gradlew , build.gradle or settings.gradle . If you already have those files in your app's directory, make sure they are committed.

Answer 2

Heroku only detect automatically Grails 2.0 apps.

To deploy a Grails 3.0 you need to follow Deploying Gradle Apps#Grails-3

Basically you need to add some tasks into your gradle.build and create a Procfile
