Difference between eclipse for java developer and eclipse for java ee developer, eclipsedeveloper

Eclipse is a plug-in-based software. Plug-ins cannot be started and operated. They need an environment. eclipse implements this environment using osgi r4 specifications.

Osgi is a specification for dynamic modularization of java. It not only makes java programs modular, but also makes modules dynamic. The general sentence is plug-in.

The eclipse installation directory mainly includes the features directory and plugin directory. The plug-in directory stores the jar package of the plug-in, and the feature directory stores the plug-in configuration, startup, and resources.

We can use these two directories to differentiate the similarities and differences between the two versions of eclipse.

Similarities:

Some of these jar packages are common. These jar packages provide the minimum environment for running other plug-ins, such as the implementation of osgi r4.

Differences:

Because java ee is used to develop enterprise applications, more plug-ins are required. Therefore, java ee has more jar packages.

To sum up, their minimum environment is the same, that is, they will have some jar packages, and their differences are also very large. They are also reflected by the extra jar packages.

Of course, no matter which version we use, we can install more plug-ins to enrich our own eclipse.
