I. Introduction

Using the above title, I couldn't find a suitable solution. After reading many posts and repeated attempts, I came up with the following!

Note: The native IDEA version is 2019, other versions may be slightly different.

2. Error description

After pulling the project from git, the directory structure is as follows, missing the desired src directory

3. Expected effect

4. Reason Analysis

There may be many reasons, but the first thing that comes to mind should be that the pull project itself is this directory structure.

1) The currently pulled branch is the default branch, and other branches need to be pulled, such as master

At this point, you need to log in to the git remote warehouse to take a look (copy the http address of git to the browser address bar),

Verify the conjecture as shown in the figure above, the main branch does not have anything, and the required code cannot be pulled through git naturally.

2) Switch branches and verify the conjecture

At this point, it is enough to show that the default main branch was pulled just now, and the master branch is actually needed.

5. Solutions

Reminder: Choose Option 1 first!

Option One

As shown in the figure below, click the "Git:main" icon in the lower right corner of IDEA, click in turn: select origin/master (the branch you want) --> Checkout, wait a moment, close IDEA and open it again to see the complete directory , or enter the workspace where the project is located to see the complete directory.

Option II

Use the git clone command to operate

1) In the project directory under the workspace, open the cmd window and execute the following git command

2) git clone -b branch name git address

git clone -b master http://56.122.220.7/root/demo-java.git

third solution

1) Select VCS in the IDEA menu bar, and operate in sequence

VCS-->Git-->Pull-->A small pop-up window-->Under the Branches to merge: option, check the branch you want to pull-->click the pull below, and wait for a while under normal circumstances. .

不出意外的话，意外还是来了……

2）拉取失败，报refusing to merge错误

错误信息，如下图所示

Git pull failed

refusing to merge unrelated histories （拒绝合并不相关的历史）

3）解决方法

打开Terminal窗口，执行如下命令：

git pull origin master --allow-unrelated-histories

反之，如果在push的时候报refusing to merge unrelated histories （拒绝合并不相关的历史）

这个错误时，执行如下命令：

git push origin master --allow-unrelated-histories

至此，需要拉取的java代码就被拉取下来了

六、拓展

1）拉取的maven工程不被识别为maven项目

解决步骤：右键pom.xml 然后选择【Add as Maven Project】之后就会当成maven项目。

2）从git拉取SpringBoot项目后，大量爆红，不能启动，不识别依赖包
