I recently created a code module generating from maven archetype,
when I imported it into my IDEA project structure as usual,
I found that the VCS contorl function is missing from right-click menu,
then I realized that I didn't make a git remote repository yet,
so I finished those processes continuously,
however, the VSC control function stll not been shown,
then I removed the module from project structure
and imported them again, the function reappeared.
this lesson told me that, VCS need to be done at very first before importing into IDEA.
