If we want to know how long the execution of a Grails task takes we can enable profiling. If we enable profiling we can see for example how long it takes to compile the source code. We can enable the profiling information by setting the system property
grails.script.profile with the value true.
$ grails -Dgrails.script.profile=true compile
Another way to enable profiling of the Grails tasks is to set the property
grails.script.file with the value true in
// File: grails-app/conf/BuildConfig.groovy ... grails.script.profile=true ...
If we run a Grails script and profiling is enabled we see the information in the console output:
