package Envelope does not exist

[Cybertizzen]

Hi, I'm having problems building the newest version of Reef, due to
the following error:

/reef/java-rest-api/src/main/java/org/totalgrid/reef/japi/
ReefServiceException.java:[26,25] error: package Envelope does not
exist

The Envelope class in the line public final Envelope.Status status; is
apparently unknown.

I tried downloading the stable release (3.0) and building this
instead, but to no avail.

Any clues on what might cause this?

Best regards,
Pål

Turned out that there were two errors, both regarding protocol
buffers, that caused this;

The first problem was windows style slashes in the values of some of
the pom tags for this project. The second problem was me running the
wrong runtime version of protobuf. Downloaded and built 2.3 - problem
solved.
