compile proto error in LAN

[bighunter513]

I use this plugin ok when My server is connected the internet,
But my company has submit code to a local network perforce depot server,
after someone sync files from depot, they cann't compile proto, got the below errors:

./rebar3 compile
===> Plugin rebar3_gpb_plugin not available. It will not be used.
===> Plugin rebar3_gpb_plugin not available. It will not be used.
===> Verifying dependencies...
===> Compiling proto_app
===> Unable to run pre hooks for 'compile', command 'compile' in namespace 'protobuf' not found.
make: *** [all] Error 1

the gpb-plugin src files are in _build/default/plugins/rebar3_gpb_plugin/src
the gpb src files are in _build/default/plugins/gpb/src

what can I do to fix the problem ?

you probably need to also sync the contents of _build/plugins which is where rebar3 keeps the project's plugins
