Hi,  
I got an error on running my sonar-scanner sources:

```auto
java.nio.file.InvalidPathException: Trailing char < > at index 75: E:\BuildAgent\work\c76803df29afe460\KE\sources\\\Common\KEService_defines.h

```

and I see that in build log trailing space in the of a file, but it is missing in the filename.  
The error is reproduced on sonar-scanner v4.6.2.2472 and v4.7.0.2747.  
Can someone help?

What version of SonarQube are you using?

Take a look at this thread – it may not be the file names on the filesystem that is the issue

> [@Build-wrapper-dump.json does not match analyzer 6.20.4.45706 version](https://community.sonarsource.com/t/build-wrapper-dump-json-does-not-match-analyzer-6-20-4-45706-version/62245/7):
>
> Nope, the actual file names are fine wink The resolving of the includes in c++ causes this issue. Something like this #include "detailtextdlg.h " Will be resolved to a path with trailing whitespaces, which causes the error in WindowsPathParser. The Issue is solved by executing regex search and replace of all include statements that contained a trailing space, for example, #include "detailtextdlg.h " to #include "detailtextdlg.h" i.e: our builds are green again wink

Thank you for help!  
The root cause was really in the whitespace in #include this file, we found it and verify fix and now build status is green.

Thanks for the follow-up! I can also let you know that in the next release of SonarQube, [we’ll make sure this no longer fails the analysis](https://sonarsource.atlassian.net/browse/CPP-1952).
