Hey I'm having a problem publishing a Java8 SBT Project to Sonatype.
When I run the publishSigned target, javadoc is complaining about Java8 features yet the code is compiling fine. If I put a scala file in the project, then scaladoc can compile it fine which is how I published it but now it's tagged with a scala version (_2.10).
Project is here - I'm assuming this is environment related though. javadoc on path is pointing to the same javac that is compiling the code. It's complaining about java8 features (eg lambdas - use of ">")

[error] (compile:doc) javadoc returned nonzero exit code
[error] Total time: 2 s, completed 9-Feb-2015 10:44:25 PM
The first two warnings emerge from the Javadoc linting that has been added in Java 8. You can either document your type parameters or disable linting using -Xdoclint:none.
The last four warnings are caused by your < and > that the Javadoc tool treats as HTML tags, you'll need to escape them using < for < and > for >.
