After you have configured Tomcat in Java EE Eclipse, you can run the test modification project directly without having to package it into Tomcat to run the view. However, when a team develops a project, the developer's eclipse configuration and project configurations will be very labor-intensive, such as their respective build class path, the different versions of each plug-in, and the different third-party jar packs they refer to. A player in the local compilation, testing, packaging, deployment is no problem, can be on the other team members of the machine is not normal operation.
If you want to avoid duplicate configurations on different machines, control conflict risk early, and manage project dependencies more reliably, you need to use project management tools. MAVEN is a project management tool that includes a project object model, a set of standard collections, a project lifecycle, a dependency management system, and the logic used to run a plug-in goal that defines the lifecycle phase. In short, it can be used for project building, publishing, and project management.
