IllegalStateException in CFamilySensor after latest plugin version

[bob (Bob Cardillo)]

Must-share information (formatted with Markdown):

• which versions are you using (SonarQube, Scanner, Plugin, and any relevant extension)
  • CFamily plugin version: 6.36.0.52033
  • SonarQube version: 9.6.1.59531
  • Code analysis azdevops task version: 4.30.0
• what are you trying to achieve
  • After upgrading to latest release of SonarQube, our scan of C++ projects started failing with IllegalStateException as com.sonar.cpp.jni.FileSystemOperations.realPath on an .h file. (see below for full stack)
• what have you tried so far to achieve this
  • ensure we’re on supported versions of everything (java, node, etc.)
  • search for similar posts (SonarCloud analysis failing with CFamily plugin version: 6.31.0.44497 - #7 by Abbas_Sabra, At com.sonar.cpp.jni.FileSystemOperations.realPath(FileSystemOperations.java:51))

Our last successful scan was a few days ago when the CFamily plugin version was 6.32.0.44918

It seems in past this was something that needed to be fixed in the CFamily plugin. Here’s an excerpt of the Azure DevOps pipeline code analysis task where the error is reported including the full java stack:

I can grab more logs and share unredacted info privately as needed. Thanks!

Hello @bob,

It looks like you are affected by a known issue when include directive contain an extra dot at the end of the file name: [CPP-3750] - Jira

In your case, the source code probably contains something like:

#include "Practice/EligibilitySetupDlg.h." // Notice the extra '.'

While this extra dot is ignored when compiling your code, it becomes harmful during analysis and generates the message you have in your log (with the extra dot too).

@bob

2022-09-02T21:25:44.8531196Z java.lang.IllegalStateException: C:/agent3/_work/1/s/Practice/Practice/EligibilitySetupDlg.h.

Even is we plan to support this situation in the future, correcting your code is probably the way to go.

That makes perfect sense, thanks!
