Show line that created the error

[MartyLake]

Hello,

Executing plantuml from the command line gives me the line where an error happened, for example:

$ plantuml -tutxt ./test.puml
Error line 74 in file: ./test.puml
Some diagram description contains errors

Actual

Using this plugin, if the plantuml source has some mistakes, nothing happens.

Expected

some text Error line 74`` is appended before the @startuml, and typing :copengets me to the line74`.

Best,
