As Grails adoption grows within an organization, it is likely that over time different projects will end up running on different Grails versions. Consequently, developers will need to ensure they have corresponding runtime enabled within their environment. That is exactly what GVM Tool is meant to do. Unfortunately for many corporate users there is a little pesky obstacle to its use: Windows.
Following Paul’s presentation on the subject at New York Groovy/Grails Meetup we have made our Grails-based event-driven SOA proof-of-concept available in GitHub.
