Cannot install heroku's plugin

Hello I want to deploy my Java web app to heroku but it doesnt go well at all. I need to execute this command to deploy war file :

heroku deploy:war --war build/libs/GradleSample.war --app

however, when i do it, i get this message : deploy:war is not a heroku command.

So I need to run this command:

heroku plugins:install https://github.com/heroku/heroku-deploy

But I get this error messages;

▸ npm ERR! node v6.9.5 ▸ npm ERR! npm v3.10.10 ▸ npm ERR! code EISDIR ▸ npm ERR! errno -21 ▸ npm ERR! syscall read ▸
▸ npm ERR! eisdir EISDIR: illegal operation on a directory, read ▸ npm ERR! eisdir This is most likely not a problem with npm itself ▸ npm ERR! eisdir and is related to npm not being able to find a package.json in ▸ npm ERR! eisdir a package you are trying to install. ▸
▸ npm ERR! Please include the following file with any support request: ▸ npm ERR! /Users/.local/share/heroku/plugins/npm-debug.log ▸
▸ Try running again with HEROKU_DEBUG=1 to see more output.

What should i do to fix this? I really want to deploy my app on heroku. I need your help. Thank you.

Solution

  • Run this command:

    heroku plugins:install heroku-cli-deploy

    Then run:

    heroku deploy:war build/libs/GradleSample.war

    The https://github.com/heroku/heroku-deploy repo is deprecated (as mentioned in the README)
