The Eclipse IDE plugin works but is pretty slow. I wouldn't use it if I wasn't so used to autocompletion + documentation in my IDE. The module system can use the central maven repository but it doesn't accept dashes in the name like jackson-core unless you put it in quotes. (Took me a while to figure out). Ceylon doesn't have enums but you can emulate them like this: http://ceylon-lang.org/documentation/1.1/tour/types#enumerated_instances http://ceylon-lang.org/documentation/1.1/tour/types#enumerat... Otherwise it's fairly straightforward to translate java into ceylon. I love immutability by default. Only 10% of my variables/fields are actually mutable. I could reduce that percentage further if the jvm had TCO.
