in regards to build, I was talking more about when these systems became popular/hyped/adopted rather then when they were released. Maven didn't became really adopted until 2.0 came out, and, to me at least, Gradle gained traction extremely fast after Maven was adopted (along with sbt for scala and others). I think Maven laid out the foundation for the adoption of gradle. But yes, it's a lot farther apart then Grunt vs Gulp. I was more trying to show that build systems change even for very stable languages/ecoSystems (relatively speaking). In regards to problem solved - it's an interesting thought, I haven't done a lot of ui outside of web, I wonder if other people can shed some light on churn regarding ui frameworks on desktop (or even flash/silverlight/unity etc...)
