Question

I am trying to setup a build trigger for TeamCity using Mercurial as the VCS. Right now the trigger looks like:

+:/**

This trigger get fire

Answer 1

Teamcity and the syntax above are foreign to me, but if you've got scripting capabilities you can check if a changeset is a tag-only changeset by doing something like this:

if [ "$(hg log -r tip --template '{files}')" = '.hgtags' ]; then
    echo tag only
else
    echo other stuff too
fi

Just swap out tip for whatever changeset you're about to act on, and change the echo statements to an exit, a make, or a hg tag as appropriate to either skip the build or just skip the creating of a new tag if the last changeset was only a tag.
