Property location and jump to location in mouse over popup

[Kiiv]

In the old pom editor, the popup on a property mouse hover show the declaration location and a link "Jump to location" allowing to jump directly in the pom where the property is declared.

Is it possible to have the same behaviour ?

I haven't researched into this much, but the Language Server Protocol (which LemMinX-maven uses) supports the Goto definition request, which could be used for this use case. LSP4E (Eclipse's implementation of the Language Server Protocol) seems to support Goto definition.

So from an LSP-point of view it should be possible.

However, from my understanding, LemMinX-Maven uses the Maven Project model in order to get the project properties.

There doesn't seem to be any API for the Maven Project to find out where these properties are declared. So some work would probably have to be done by LemMinX-Maven to manually scan the project and find out where properties are declared. I'm not sure how feasible this is to do (could LemMinX-Maven perform this scan upon loading up the project, and re-scan periodically when the project is modified? Could the workspace diagnostics request maybe be used for this, and does LSP4E implement it?)

definition/F3 works for properties (IIRC you implemented years ago @AObuchow ;).

This can be achieved without particular action, we can (and should) simply put links of the form file://path/to/file#L34,1-L35,3 in the documentation and those should properly open the right file and select the right range. cc @vrubezhny

@mickaelistria I'll take care if no other contributes a fix earlier.
