1 Create a warehouse
The following uses gitee as an example to introduce, and the operation of github is similar.

Create warehouse

Click "+" at the top right of the page and select "Create Warehouse"

to set warehouse related information

First enter the warehouse name, which can usually be the same as the project name in IDEA. Whether it is open source or not can be selected according to the needs. The private selected here (the project can only be seen by yourself)

is private by default. You can set it as open source after the creation is completed.
Then click the "Create" button below.
At this point, the warehouse creation work has been completed on gitee.

Copy the current warehouse path, which needs to be used later when IDEA uploads the project.

Import the project into version control in IDEA

Select in order in the IDEA menu bar: VCS->Import into Version Controlp->Create Git Repository

The purpose is to create a git warehouse locally first,

click the "OK" button in the pop-up box. Find the path of the project you want to upload.

Right-click the project name, and select in order in the pop-up menu bar: Git->Add

The purpose is to add the content that is not in the local warehouse in the current project to the local warehouse (in fact, it is not really added, it will only be added in the next step, but all files that are not in the warehouse need to be added before they can pass the following steps to add to the repository!)

to commit the changes

Right-click the current project name, select in the pop-up menu bar: Git->Commit Directory,

and then enter the comments for this submission, for example: the first submission (Note: You must enter content here, otherwise you cannot submit). Then click the Commit button to submit locally.

Purpose: The purpose of submission is to save the current project in the local warehouse

. After that, click 1:Project on the left side bar of IDEA to return to the project structure view and
right-click the project name, and select in order in the pop-up menu bar: Git->Repository- >Push

The purpose is to synchronize the content saved in the local warehouse to the server (upload to the server, and make the warehouse in the server consistent with the content of the local warehouse).

For the first operation, you need to configure the server warehouse address, click Define remote in the pop-up box

In the URL input box in the pop-up box, add the warehouse path created on gitee (the warehouse path copied on the page in the first big step and the last small step), and click the OK button

After that, IDEA will automatically check the link, and if there is no problem, click the Push button below

When submitting for the first time, you are required to enter the account number and password on gitee. After entering, you can select Remember to remember the password, and you do not need to enter it later.

Enter the username and password registered in your own git.

At this point, the submission is completed, and a prompt will be displayed at the bottom right.

Submitted successfully! ! !

Solution to push failure

At this point, click the IDEA test console option to open the console view:

execute the following three commands in the console in sequence:

git pull
git pull origin master
git pull origin master --allow-unrelated-histories

Then try to push again.
