java - Heroku - git push/deployment 期间出错，此代码的相同版本已经构建

Question

我在将 springboot 应用程序部署到 Heroku 时遇到问题。运行后git push heroku master ，我遇到以下错误:

我不知道为什么会发生这个错误。我有两个远程存储库，用于推送代码，一个来自 Heroku，另一个来自 Github。我根据这个问题的答案尝试了以下命令，Heroku: If you are developing on a branch and deploying via git you must run:

git push heroku master:main

但错误仍然存​​在。我可以在 Heroku CLI 上尝试任何命令来解决这个问题吗？

经过几次尝试，我想问题的原因可能是 中断 git push heroku master命令，然后通过重新执行相同的命令继续执行，导致以下错误:

remote:  !     Push failed
remote:  !
remote:  ! ## Warning - The same version of this code has already been built:             31199a7acec03a3cb614ebaaf6c7720cee6684bd

remote:  ! at least twice. One common cause of this behavior is attempting to deploy         code     from a different branch.
remote:  !

所以我所做的是，我推送了另一个提交，然后重试了相同的命令 git push heroku master ，从而成功部署。
另外，请大喊 RainXCat's answer and insights ，现在我知道 Heroku 不允许在同一目录/文件夹中存在两个 git 存储库。
