false Static Analysis Warnings with symlinks in ClearCase

[Graham Menhennitt]

We're using the latest Jenkins on Linux to build a project that is stored in ClearCase. Everything builds correctly, but we get some Static Analysis Warnings when we shouldn't.

When the ClearCase plugin gets the project's files, I can see in the Console Output:

14:22:36 New:                     vobs/1062_GEN3/configuration/tools/CSU/device_get_logs_info.sh /main/Integration/2 
14:22:36 New:                     vobs/1062_GEN3/configuration/tools/RIU/device_get_logs_info.sh "symbolic link d6377eb4.fc7711e5.8fd8.00:50:56:bc:54:8e" SYMLINK

So, that's a text file in one directory and a symlink to that file from an adjacent directory.

We have Scan For Compiler Warnings enabled with Scan Console Log with parser GNU C COmpiler 3 (gcc). The build reports:
GNU C Compiler Warnings: 1 warning
Static Analysis Warnings: 1 warning

When I click on the warning links, they both take me to the same place which is the above symlink. Clicking through to the warning message, I get the stack trace below. Note that it seems to be taking the "New:" and a lot of spaces as part of the file name.

There are other similar symlinks in the project that don't produce any warnings. I've tried destroying and recreating the link. I've tried swapping around the file and the link (i.e. make the link point in the other direction). No joy.

Does anybody have any clues, please?

Thanks,
  Graham

Please create a new bug report in the issue tracker for the warnings plugin. Paste the offending console log snippet into the description (with {norformat} tags), maybe the regular expression of the gcc parser can be improved.

Viele Grüße,

Ulli
