jhipster application deployment to Heroku giving error

Question

I am trying to deploy my jhipster generated application to heroku using ubuntu. When I type:

echo $JAVA_HOME

, I am getting /usr/lib/jvm/java-8-oracle

But while deploying the application to heroku using jhipster command, I am getting the below error.

    sudo jhipster heroku

Congratulations, JHipster execution is complete!

Even my JAVA_HOME is pointing to Java-8-oracle, why jhipster throwing error saying JAVA_HOME is pointing to something else and any fix for this

If you manually edit the herokuDeployType value in your .yo-rc.json to this:

"herokuDeployType": "git"

Then the next time you run jhipster heroku it will run Maven on Heroku.
