Erlang/rebar3 properly handle {vsn, git} in .app.src files - reported as error in plugin

Report

Erlang & rebar3 properly handle {vsn, git} in .app.src files.

Plugin incorrectly reports <expression> expected, got 'git' for that construct.

Environment

• OS: FreeBSD 13.0p5
• IDE: IntelliJ IDEA Ultimate #IU-213.6461.79 (manually installed)
• Plugin: 0.11.1129 (installed from IDE)
• Erlang: 24 [erts-12.1.5] (native binary pkg version 24.1.7,4)
• rebar 3.16.1+build.5060.ref6e79ef6c (self-compiled)

[ignatov]

Could you please add a tiny example of a code with "errors", that's going to be very handy.

[p-kraszewski]

Yes, of course.

Input files

The source is unmodified rebar3 new app, except for mylib.app.src.

{application, mylib,
 [{description, "An OTP application"},

  {registered, []},
  {mod, {mylib_app, []}},
  {applications,
   [kernel,
    stdlib
   ]},
  {env,[]},
  {modules, []},
 ]}.

Reported error

Output files

the autogenerated _build/default/lib/mylib/ebin/mylib.app is as follows:

{application,mylib,
             [{description,"An OTP application"},
              {vsn,"1.0+build.3.ref3b7623e"},
              {registered,[]},
              {mod,{mylib_app,[]}},
              {applications,[kernel,stdlib]},
              {env,[]},
              {modules,[mylib_app,mylib_sup]}]}.

which is the expected behavior.
