Hovering over Maven elements perhaps needs longer timeout #972

Open eliasbalasis opened 3 months ago

eliasbalasis commented 3 months ago

Continuing from https://github.com/eclipse/lemminx-maven/issues/561,

On Eclipse 2023-12, and a Maven project with large number of modules, hovering over artifacts and properties in the editor for some modules displays the expected pop-up.

However, on some other modules it times out. Could not get hover region due to timeout after 1000 milliseconds

Could not get hover information due to timeout after 1000 milliseconds

Perhaps the 1000 milliseconds timeout needs to be increased.

This is a client-side error, it should then be reported to m2e or LSP4E.
