After that, I entered a strange problem with IDEA that many classes can't be found, and the project can't be built/compiled (in IDEA), but maven install worked good. After a series of attempts, I found that IDEA activate the scala-2.10 profile by default which result in this problem. After deactivate scala-2.10 profile via sidebar Maven Projects -> Profiles -> deactivate "scala-2.10" profile, and every works good again. [嵌图片 1] I share this tip in the dev list, because a lot of my colleagues have the same issues, and maybe many other Flink devs have the same problem too. BTW, I don't know why IDEA activate scala-2.10 by default, not sure it's a IDEA bug or the wrong profile setting somewhere. Regards, Jark Wu
