[rufinio]

XSLT is optional, there should be no message.

Hello @rufinio, can you please explain the use case behind this. In general it would be good to have a description what this xslt feature is doing.

Hi @guwirth,
I am also curious what's the use case behind this xslt feature.
I have updated sonar-cxx plugin to 0.9.8 and got "ERROR: sonar.cxx.other.xslt.1.inputs file is not defined." without using this feature.
I found the closed issue #1277 that already dealt with this but obviously it was not solved.

@rufinio :-) the original idea was #1096. Idea is to have a built-in preceding XSLT transformation for the sonar.cxx.other. sensor. Therefore I was wondering what you are doing with it without assigning an XSLT? Setting inputs and outputs without an xslt makes no sense to me.

But you are right that sonar.cxx.other. should work without inputs, outputs and xslt.

use #1367 instead
