use “git branch --unset-upstream“ to fixup

On branch master
Your branch is based on 'origin/master', but the upstream is gone.
  (use "git branch --unset-upstream" to fixup)

Untracked files:
        .gradle/
        .idea/
        build.gradle
    ...

nothing added to commit but untracked files present

遇到这种问题, 要是项目是新提交的.

可以将.git删除. 重新创建,并强制提交即可.

引起原来,是之前没提交成功.
