Teamcity build trigger exclude all but some

Question

I'm using teamcity to perform my builds.

within my repository there are multiple projects that uses different folders. e.g. like this:

└root
  ├project1
  │  └files
  ├project2
  │  └files
  └project3
     └files

I have 3 lanes that should all here just on there own folder.

The current trigger configuration for project2 looks like this:

-:*/project1/*
-:*/project3/*
+:*/project2/*

but I don't want to explicit add all projects to the trigger configuration of every project. therefore I would like to say s.th. like

-:IGNORE_EVERYTHING
+:*/project2/*

which means I just want to list the folder that SHOULD get monitored but not exclude all others. When I just use the last line of the above the two other folders gets monitored as well.

How do I do that?

According to documentation Configuring VCS Triggers:

When entering rules, please note that as soon as you enter any "+" rule, TeamCity will remove the default "include all" setting. To include all the files, use "+:." rule.

You don't need any exclusion rule. Just insert:

+:*/project2/*

in Trigger Rules and you should be good.
