This behavior is similar to what Cedric and I saw when playing with RoboVM:
https://github.com/msgilligan/robovm-groovy-test/blob/master/src/main/groovy/HelloWorld.groovy I like the approach that Mike Hearn proposed for Kotlin in this blog entry: https://blog.plan99.net/kotlin-native-310ffac94af2 This is not the path that JetBrains chose, but Mike is privately working on it (with a Kotlin focus, obviously). I wonder of such an approach might work for Groovy (with the appropriate Groovy compiler support, of course) -- Sean On 5/8/17 8:02 AM, Paolo Di Tommaso wrote: > Dear all, > > I just want to share with you my experience with the Java AOT compiler > <http://www.oracle.com/technetwork/oracle-labs/program-languages/overview/index.html> > a came across a few days ago. > > > Although they said clearly that it still an experimental project and > it does not support dynamic class loading and most of reflection, I > turns out it's possible to compile a basic static Groovy class, eg: > > @groovy.transform.CompileStatic > class Hello { > > static void main( String... args ) { > System.out.println "Hello world!" > } > } > > > This mean that it creates a native 5MB binary executable, that can run > on any machine without the need of the Java VM nor the Groovy runtime! > in 12 millisecond! cool!! > > > Unfortunately the good news stops here.
