Static typing was grafted onto Apache Groovy in 2012, but no-one really uses it. I'm not sure about its reliability -- its use never took off on the Android platform, and none of the Groovy codebase itself has ever been rewritten in static Groovy. Groovy's still great for scripting on the JVM though, for stuff like those 10-liner build scripts for Gradle, glue code, and mock testing. Just don't use Groovy for building systems -- use a language based on static typing from the ground up, like Java, Scala, or Kotlin.

  Both your examples use very simple logic. The Apache Groovy codebase example is of some peripheral functionality, i.e. a builder. All the methods in your Grails codebase example are, at most, 1 line long. I can't be bothered re-investigating what proportion of the core Groovy codebase really uses static compilation -- it certainly wasn't much only 2 years ago. As for Grails, virtually no-one has upgraded from v.2 to Grails 3 since it was released 2.5 yrs ago, or started many new projects with it.

    i was just saying i personally found type declarations useful as the couple of small groovy codebases i worked on progressed over the short period (maybe a year?) i worked on them. thinking about how i might declare types made me decompose things a bit differently, which made the logic simpler in some places, which allowed me to do things like get rid of tests where i checked the behavior in a case where a method was missing on a function parameter, because now i knew the parameter was over certain type (and thus would have that method).
