jenkins trigger build if new tag is released
Solution 1:
Set refspec to: +refs/tags/*:refs/remotes/origin/tags/*
branch specifier: **
Under build triggers check Build when a change is pushed to GitHub
Solution 2:
What do you mean by new tag? Does it has some template name?
You can surely define it in Advanced --> Refspec -->refs/tags/{tagname}
.
You can even do refs/tags/*
for finding really ANY new tags.
