ERROR:
ERROR: Re-run SonarQube Runner using the -X switch to enable full debug logging.

Sonar claims my file is invalid, but the C++ compiler doesn't have any problems...

[LegalizeAdulthood]

SonarQube 4.5.2
Plugin version 0.9.2

[wenns]

Thanks for the issue. Can you provide the code snippet which causes this?
@lcintrat: Can you have a look, please?

[LegalizeAdulthood]

It's a closed source project, so I will have to ask about sharing code. They may say yes.

[guwirth]

We need not the whole code, only a small snippet to reproduce the problem.

[LegalizeAdulthood]

It's one of our "dustier decks", I'm not sure if a small snippet outside the context of the entire file will reproduce the problem.

[lcintrat]

Oops I didn't see it. I will have a look.

[lcintrat]

@LegalizeAdulthood can you confirm that the NPE happens with an anonymous enumeration, something like:

enum {};

[LegalizeAdulthood]

How do I know which file was being processed when the exception occurs?

I tried with the following source code:

enum { };

This completed without error.

From the -X log on our full source, I think I am getting the NullPointerException in the file ijldefs.h which originates with the Intel JPEG library. However, I can't find source to this out on the net, so I suspect it is commercial 3rd party source and not open source. However, I did see that this file contains a bunch of enum declarations in the global namespace. They all create a typedef in this form:

typedef enum { /* possibly some enum values */ } FOO;

So I tried a small .cpp file with this sort of declaration in it, and I couldn't reproduce the crash there either.

[lcintrat]

@LegalizeAdulthood Nice !
But the API documentation visitor parses only .h header files :)
However, I already committed a fix for the unnamed enum.

[LegalizeAdulthood]

I can reproduce the problem with an anonymous enum in a header included by the .cpp.

Is there a way to turn off specific decorators from the sonar-project.properties file?

[lcintrat]

Ok so you can give a try to #431. I think this is the same problem.
