Got a problem with default_release option in config

[stleon]

In rebar.conf:

{relx, [
    {default_release, dev, "1.0.0"},
    {release, {prod, "1.0.0"},[
        apps
    ]},
    {release, {dev, "1.0.0"},[
        apps,
        sync,
        observer,
        wx
    ]},
    {dev_mode, true},
    {include_erts, false},
    {extended_start_script, true},
    {vm_args, "conf/vm.args"},
    {sys_config, "conf/sys.config"}
]}.

Have error:

No default release name was specified and there are multiple releases in the config: prod, dev

Copied from here

Is it the same error if you do {default_release, {dev, "1.0.0"}}?

Yes
