Github user andschwa commented on the issue: https://github.com/apache/mesos/pull/247 @mpereira Oh I know what's going on: > Please make sure Java proto files are generated in ../build/src/java/generated folder. The site generator expects the build to have been run, at least to the point of proto files being generated. Try ``` mkdir build cd build cmake -DENABLE_JAVA=ON .. cmake --build . --target mesos-protobufs ``` And then try generating the site again, I think it'll work.
