I was experimenting with the java and C++ builds with the 2015 toolchain, and wanted to be able to switch between the two. After having C++ Deploy vanish several times and having to reinstall wpilib, and reading last year's thread on this topic, I found that I could preserve the C++ Deploy from disappearing (it seems to get wiped out when the java perspective is activated) by keeping a separate workspace for the my java and C++ projects. Then do File->Switch Workspace when you want to switch. I might have switched perspectives before switching workspace too, but not sure if that matters. Eclipse restarts but that's OK. Not sure if that is the only way; it worked for me.
