Java Heroku application run locally with foreman

Question

I'm following the "Getting Started with Java on Heroku" guide at https://devcenter.heroku.com/articles/getting-started-with-java I follow the steps till I deploy and execute succesfully the application downloaded from GitHub. When I try to execute it locally on Windows XP with the command

foreman start web

I get the error:

    web.1  | started with pid 3388
    web.1  | Error: Could not find or load main class Main
    web.1  | exited with code 1
    system | sending SIGKILL to all processes

My Procfile is:

web:    java %JAVA_OPTS% -cp target\classes:target\dependency\* Main

And

>echo %JAVA_OPTS%
-Xms256m -Xmx512m

Can anyone suggest me how to solve?

Answer 1

I ran into this issue while running through the https://devcenter.heroku.com/articles/getting-started-with-java tutorial.

After tinkering with some of these answers I discovered that step six at https://devcenter.heroku.com/articles/getting-started-with-java#define-a-procfile tells the answer.

When you see instructions to run your app with foreman, append an extra -f Procfile.windows flag to ensure your Windows-specific Procfile is picked up. For example: foreman start web -f Procfile.windows

Once I switched to the foreman start web -f Procfile.windows command, everything worked smoothly.

Answer 2

Quotes and semicolon

web: java %JAVA_OPTS% -cp target\classes;"target\dependency\*"  Main
