Maven 部署到 heroku 错误

Question

I'm trying to deploy a java/maven application to heroku platform, everything goes ok until I try to access the result link. Despite of successfully build the link I open shows this error:

        An error occurred in the application and your page could not be served. Please try again in a few moments.

        If you are the application owner, check your logs for details.

Thanks :D

Answer 1

That's not an error. But your build output shows that you don't have any process types defined (which means heroku won't know how to run your app):

Procfile declares types -> (none)

You'll need to create a Procfile and add it to your Git repo. Most Java apps have a Procfile that contains something like:

web: java -cp target/classes:target/dependency/* com.example.Main
