"encoded string too long" error in play stage command

Question

Using play framework v2.1.1, we use command

play clean compile stage

to generate deployable artifacts. It was working fine from past many months. We have not changed anything but now when I tried same command again, it's throwing error:

[error] (compile:doc) encoded string too long: 65909 bytes
[error] Total time: 3 s, completed 7 Feb, 2017 5:35:58 PM

I have setup play again, clean all required directories but still no success. Any help would be appreciated.

I fixed this issue by removing generation of java api docs. Here is what I added to my build.sbt file:

publishArtifact in (Compile, packageDoc) := false
publishArtifact in packageDoc := false
sources in (Compile,doc) := Seq.empty
