A regular expression to find in the build log.
Note that you should not specify ".*" within your multi-line pattern unless you actually want to match every character. ".*FOO.*" will match the entire build log, assuming it contains "FOO" somewhere.
Substitutions may be made within the description with placeholders of the form ${I,G}, where
I is the indication number and G is the captured group within the indication
expression. e.g., ${1,1} would be replaced with the first indication's first captured group
and ${1,2} would be replaced with the first indication's second captured group.
