Is there a solution?

In fact, IDEA has already prepared for us: the ignore plug-in.

Install the ignore plug-in

Open the settings menu of IDEA, search for ignore in the plugins plug-in center, and click the "install" button to install and restart IDEA

Select the project, right-click to create a new "New", and click to select .project file.

Pop-up "Ignore file Generator" window and check "Example user template"

Clicking the Generate button will generate a .gitignore file, which will automatically populate the relevant files ignored by Git.

Filter .idea, * .iml files

Filter target directories generated by Maven, etc.

Verification

From the project, we can see that the directories that are not controlled by the Git version are grayed out.
