Issue with latest rebar3

[phani35]

I am observing below issue with latest rebar3 version 3.14.4. any idea how to solve this problem?

===> 	{post_hooks, [{compile,
                                  "escript build/prepend_edoc_autogenerated src/gpb_scan_old.erl        src/gpb_scan_old.xrl"},
                              {compile,"escript build/compile_descriptor"}]}.
Compiling descriptor.proto...
escript: exception error: undefined function gpb_compile:file/2
===> Hook for compile failed!

did you find a way around this? is there a simple example that shows this behaviour?

No. as of now I rollbacked to rebar3 3.13.0 and it is working fine there.

Can you look into this problem, you can reproduce the problem just by running "rebar3 compile" in topdir of rebar3_gpb_plugin.

rebar3_gpb_plugin]$ rebar3 compile ===> Verifying dependencies... ===> App gpb is a checkout dependency and cannot be locked. ===> Analyzing applications... ===> Compiling gpb Compiling descriptor.proto... escript: exception error: undefined function gpb_compile:file/2 ===> Hook for compile failed!

Can you try the same by keeping gpb in _checkouts folder, it seems the problem persists when dependencies are managed in _checkouts folder.

If I mention gpb dependency path as below , it is not taking the defined path from rebar.config during compile stage . It is always trying to fetch from hex.pm

{deps, [
{ gpb, {git, "https://github/localgitrepopath/gpb.git", {tag, "4.17.3"}}}
]}.

Thank you very much for quick response.

[lrascao]

are you running rebar3 upgrade gpb after changing rebar.config?

[phani35]

Yes, the upgrade is run after rebar.config is changed.
