Is Java 8 compatible with GWT 2.6 or 2.7? [duplicate]

Question

I have an application which is developed using GWT 2.6 and Java 7. Now I am updating it to Java 8 with GWT 2.6.

1. Is GWT 2.6 compatible with Java 8? Will it build/compile fine?
2. Is GWT 2.7 compatible with Java 8? Any suggestion?

Answer 1

If you're only interested in using a JDK 8 to compile your application, without using Java 8 language constructs, then GWT 2.6 and 2.7 will work.

Java 8 as a source language won't be supported before GWT 2.8 though, as already pointed by others.
