Re: After Build Custom Label Incrementer Problem

The model for CruiseControl is that the value of the label is
determined before the build -- the value of the label is one of the
value passed into the build, so it has to be determined ahead of time.

You are trying to have the label determined by the build. That won't work.

What you could do is call your build script with a bootstrapper to
write the current label to a file, then use your custom label
incrementer to read that and set it as the label -- but you'll need to
make it a preBuildIncrementer so that it can set the label before the
build.

Does that makes sense?
