## Getting Started with IDEA Remote Development This document provides step-by-step instructions for setting up and using IDEA's remote development environment. **Environment Setup** 1. **Clone your Git repository**: - Visit the GitHub repository: `git clone https://github.com/zq2599/blog_demos.git` - This will download the project files to a directory named `blog_demos` on your local machine. 2. **Configure your remote server**: - Open a terminal on your Ubuntu server running JetBrains IDE. - Run the following command: `remote add origin git@your_remote_server_ip:path/to/repository` - Replace `your_remote_server_ip` with the actual IP address of your remote server and `path/to/repository` with the actual path to your Git repository on the server. 3. **Start an IDEA remote server**: - Open the "Settings" (macOS) or "Preferences" (Windows/Linux) and search for "Remote Development". - Click on "New" and select "Remote Server...". - Enter the server's IP address, port number, username, and password. - Click "Add". - The server will be started and the connection details will be displayed. 4. **Connect to your remote server**: - Open a terminal on your local machine. - Run the following command: `idea --remote-connect :` - Replace `` with the IP address of your remote server and `` with the port number specified in the server's configuration. 5. **Set the project directory**: - Open the "File" menu and select "Project Structure...". - Select the directory containing your Java project. **Project Structure and Development** 1. **Navigate the project structure**: - You should now see the project directory structure in the IDE's project view. - You can use the project structure panel on the left side to navigate through the different folders and files. 2. **Compile and run the application**: - To compile and run the application, right-click on the project root in the project structure and select "Run". - This will launch the application and execute the code in the server's environment. 3. **Debug the application**: - To debug the application, follow the same steps as you would for a local development environment. - You can set breakpoints and inspect variables and stack traces. **Remote Development Features** - **Remotely open directories**: - To open a directory on the server, right-click on it in the project structure and select "Open in". - This will open the directory in a remote editor, such as Visual Studio Code. - You can also use the terminal in the server to navigate and edit files. - **Remotely manage projects**: - You can create, edit, and delete projects on the server directly from the IDE. - You can also manage project dependencies and build settings. **Additional Tips** - You can save frequently used configurations in the IDE's settings. - You can install plugins to extend IDEA's functionality for remote development. - Remember to save your Git repository on the server for version control. - Close and keep the remote server connection open for uninterrupted development. **Conclusion** Following these steps will allow you to set up a remote development environment using IDEA and enjoy its benefits. By connecting to your remote server, you can develop and debug Java applications with ease and efficiency.

本篇概览

IDEA的远程开发功能，可以将本地的编译、构建、调试、运行等工作都放在远程服务器上执行，而本地仅运行客户端软件进行常规的开发操作即可，官方给出的逻辑图如下，可见通过本地的IDE和服务器上的IDE backend将本地电脑和服务器打通，实现了远程开发的效果

实际体验中，感觉就像平常的IDEA本地开发，但其实繁重的任务都交给了服务器去做，这对性能较差的本地电脑来说，以前跑不动的应用，如今凭借强大的服务器也能丝滑运行了
今天就来一起实战IDEA远程开发，让破旧的本地电脑也能流畅的编译运行Java应用
文章由以下几段组成：

准备服务器
IDEA远程连接
重新设置工程的根目录
端口转发
其他要注意的地方

环境信息一览

以下是我这边本次实战的环境信息，可作为参考

IDEA：2021.3.2 (Ultimate Edition)
本地电脑操作系统：macOS Montery（12.3）
服务器：Ubuntu 20.04 LTS（4核8G）

准备服务器

一台Linux服务器是远程开发必须的，自己内网的、租用云服务厂商的都可以
IDEA会自动在服务器上安装所需的服务，咱们无需提前准备什么，唯一要求是可以通过SSH登录此服务器
欣宸的服务器是腾讯云轻应用服务器，在官网租用的，如下图，4核8G，一年两百多，感觉挺划算
接下来要在服务器上把开发用的代码准备好，我这里是将自己github仓库下载到服务器上，代码存放在这里：/home/ubuntu/jetbrains-workspace

ubuntu@VM-12-12-ubuntu:~/jetbrains-workspace$ git clone https://github.com/zq2599/blog_demos.git
Cloning into 'blog_demos'...
remote: Enumerating objects: 14559, done.
remote: Counting objects: 100% (1097/1097), done.
remote: Compressing objects: 100% (350/350), done.
remote: Total 14559 (delta 846), reused 818 (delta 703), pack-reused 13462
Receiving objects: 100% (14559/14559), 110.29 MiB | 3.05 MiB/s, done.
Resolving deltas: 100% (4714/4714), done.

IDEA创建远程连接

服务器端准备完毕后，可以开始本地电脑的远程连接操作了
打开IDEA，如下图，选择New Connection

输入IP地址，账号密码
按要求输入密码，远程连接成功后，指定工作目录（Project directory），我指定的是代码仓库所在目录，然后点击右下角的Download and Start IDE
远程服务器开始下载后端应用，这是用于支持远程开发的服务
等待下载完成后，就会多出一个名为JetBrains Client的应用，并且已经打开，如下图红框，这就是将来做远程开发的本地工具了

JetBrains Client界面如下，看起来像是IDEA，可以看到刚才在服务器下载的整个仓库的内容，和在本地打开没什么区别，Terminal打开的也是服务器目录，修改代码时改动的也是服务器上的代码
还剩一个问题：如上图所示，此仓库中并不只有一个java项目，而是有几十个文件夹，每个文件夹下都是个独立的工程（有的是gradle，有的是maven），如果我现在只想修改其中的一个（例如上图红框中的quarkus-tutorials），并编译运行它，应该怎么操作？接下来就解决此问题（这是IDEA的操作，并非远程连接的问题）
