Premise: The JDK environment has been configured, the tutorial can be seen (1) https://blog.csdn.net/m0_73964392/article/details/129393142?spm=1001.2014.3001.5501
Eclipse：http://www.eclipse.org
http://www.eclipse.org can be opened directly.
Click DOWNLOAD in the upper right corner to download the latest version
Click download again to download automatically, if there is no response, please click here.
The next step is to open the downloaded file and select the first one
Choose a good path and wait for a long install...
If there is no special requirement, just go to next directly. Try not to select the path on the C drive (warning of fried C drive). I will not expand it in detail here.
Special mention is the bundle-pool (bundle pool) option, which can be checked here (the path is optional)
Simply put, a bundle pool is a mechanism that allows multiple Eclipse applications to share a common set of plugins (bundles). Without it (i.e., using the traditional Eclipse IDE download), each Eclipse application has its own independent set of packages, which in practice means that there is a lot of duplicate storage of these packages (since many Eclipse-based applications contain many of the same Bag).
At this point, the basic installation is complete, you can select New in the upper left corner to create your project file and write code.
