How to create a Java project template?

Use eclipse plug-in development (RCP, the swt/jface you mentioned) to make a plug-in.

First create a template project, which is an ordinary project that you want to use as a template ;

Then make a plug-in, which can be a button. Click to pop up a dialog box to make some basic configurations, such as project name, path, etc. After confirmation, the template project will be copied to the target workspace. , and then change the project configuration (generally, your project root directory will have basic attribute files of the project, .project, .classpath, etc., you can use plug-ins to edit them directly), then import the project, and the template will be imported
