"rebar3 as prod tar" overlay does not take effect

[leonlee2007]

When upgrading rebar3 of an umbrella project from 3.12 to 3.19, I encounter a problem:
Packaging with rebar3 as prod tar, it is found that the overlay configured in the app does not replace the general overlay.
but rebar3 as prod release is ok.

Try to modify the code of relx.erl:
https://github.com/erlware/relx/blob/main/src/relx.erl

build_release_(#{name := RelName,
                 vsn := RelVsn}, Apps, State) ->
    Release = rlx_state:get_configured_release(State, RelName, RelVsn),
    {ok, RealizedRelease, State1} =
        rlx_resolve:solve_release(Release, rlx_state:available_apps(State, Apps)),
    {ok, State2} = rlx_assemble:do(RealizedRelease, State1),
    _ = rlx_overlay:render(RealizedRelease, State2),
    RealizedRelease.

build_tar(Release=#{name := RelName,
                    vsn := RelVsn}, Apps, State) when is_atom(RelName) ,
                                                      is_list(RelVsn) ->
    RealizedRelease = build_release_(Release, Apps, State),
    build_tar_(RealizedRelease, State),
    {ok, RealizedRelease};

Change it to the following:

build_release_(#{name := RelName,
                 vsn := RelVsn}, Apps, State) ->
    Release = rlx_state:get_configured_release(State, RelName, RelVsn),
    {ok, RealizedRelease, State1} =
        rlx_resolve:solve_release(Release, rlx_state:available_apps(State, Apps)),
    {ok, State2} = rlx_assemble:do(RealizedRelease, State1),
    _ = rlx_overlay:render(RealizedRelease, State2),
    %RealizedRelease.
    {ok, State2, RealizedRelease}.

build_tar(Release=#{name := RelName,
                    vsn := RelVsn}, Apps, State) when is_atom(RelName) ,
                                                      is_list(RelVsn) ->
    %RealizedRelease = build_release_(Release, Apps, State),
    %build_tar_(RealizedRelease, State),
    {ok, State1, RealizedRelease} = build_release_(Release, Apps, State),
	build_tar_(RealizedRelease, State1),
    {ok, RealizedRelease};

After recompiling rebar3, the problem is solved.
