Description Sergey Prigogin CLA 2010-10-23 23:50:28 EDT 
To reproduce:
1. Turn off "Do not report an error if 'else' exists" option.
2. Create a source file with the following code:

void test() {
  if (true)
    ;
  else
    printf("hello\n");
}

3. Turn on "Do not report an error if 'else' exists" option.

The warning marker on the semicolon doesn't go away. It does go away after closing and reopening the file.

I don't know how to fix it. Do I suppose to rebuild the whole workspace?
If will be updated as soon you change something in the file.
Comment 2 Andrew Gvozdev CLA 2010-10-28 09:25:42 EDT 
When you change Java Compiler Error/Warnings level it asks if you want to do a full rebuild. I think it is a sensible thing to ask.
Comment 3 Elena Laskavaia CLA 2010-10-28 20:23:19 EDT 
Normally it won't run with build only per file. If you project is 1000 files and you have 2 files open do you really want to rebuild all?
Maybe I should just clear markers for which user changes something and warn user that what would happened.
Comment 4 Sergey Prigogin CLA 2010-10-28 20:55:54 EDT 
Codan markers usually exist for a small set of files. How about recalculating markers just for those files?

Hi,

I am evaluating CDT 8.0(M7). Currently I am not using eclipse for building my project (I am building it from command line). I tried disabling all CODAN tests. I am not able to clean/remove previous codan checkers results. I tried several actions:
* closing / opening my project
* context menu on my project -> Clean Project
* context menu on my project -> Run C/C++ Code Analysis

I would appreciate any suggestions.

Thanks a lot,
Yevgeny

You can go in Problems View and apply "delete" key to the markers. Be warned about efficiency of this operation, if you trying remove a few thousands of markers it could take time (on scale of hours) to complete.

BTW I filed bug 345608 about performance. On the other hand I was able to remove ~40000 markers in no time in .metadata/.plugins/org.eclipse.core.resources/.projects/MyProject/.markers.
