SpringSource announced today that it has acquired G2One Inc., the company behind the popular Groovy and Grails technologies.

• Groovy is an open source dynamic language for the Java Virtual Machine, that offers a flexible Java-like syntax all Java developers can learn easily. Many organizations have adopted Groovy as an abstraction layer for defining business rules using Domain Specific Languages.
• Grails is an open source advanced and innovative web application framework based on Groovy, and built on proven and high performance open source platforms such as Spring, Hibernate, SiteMesh, Quartz, and Ajax libraries. Grails allows developers to use agile methodologies and principles like convention over configuration to rapidly build quality applications.

There is a FAQ covering the acquisition as well as blog posts by Rod Johnson, Graeme Rocher (Grails project lead) and Guillaume Laforge (Groovy project lead). Both Grails and Groovy have great synergies with Spring and I know that the Spring community will extend a warm welcome to Grails and Groovy users.
