[SOLVED] Missing jetty-servlet 12.0.0 dependency

Missing jetty-servlet 12.0.0 dependency

I cannot find the jetty-servlet artifact for the recently released Jetty 12.0.0

https://github.com/eclipse/jetty.project/releases/tag/jetty-12.0.0

A search for it shows that it is not present on Maven Central, where can I find it? Does it still exist?

Solution

The artifacts that are EE specific are now isolated in their own EE specific layer.

The design of Jetty 12 is that it is a Core, with no EE specifics (no Servlet, nothing) and then a bunch of Environments that provide the EE specific details.

With this new design...

The long history (since 1995) of versioning in Jetty is more consistent with normal versioning expectations.
- since 1995, Jetty versioning was <servlet_support>.<major>.<minor>
- starting with Jetty 12 it is now <major>.<minor>.<patch>
There will be fewer (if any) major version updates in Jetty.
A new Jakarta EE or Jakarta Servlet version will just cause a new Environment to pop up.
It is possible to run multiple Environments at the same time now.
Continued support for legacy javax.servlet webapps.

Eg:

Environment	Jakarta EE	Servlet	Namespace
`ee8`	Jakarta EE 8	Jakarta Servlet 4	`javax.servlet.*`
`ee9`	Jakarta EE 9	Jakarta Servlet 5	`jakarta.servlet.*`
`ee10`	Jakarta EE 10	Jakarta Servlet 6	`jakarta.servlet.*`

See the documentation about migrating from Jetty 11 to Jetty 12, and specifically the table of the maven coordination changes.
