Rebar: "Release mynode uses non existing application mynode"

Question

I've been trying to set up a simple Erlang app using Rebar but can't get it to work. I followed the instructions on http://skeptomai.com/?p=56 to the letter, and when I run `./rebar -v generate`, I get this error: ``` ==> Entering directory `/home/adam/erlang-test3/testing-rebar/apps/myapp' WARN: 'generate' command does not apply to directory /home/adam/erlang-test3/testing-rebar/apps/myapp ==> Leaving directory `/home/adam/erlang-test3/testing-rebar/apps/myapp' ==> Entering directory `/home/adam/erlang-test3/testing-rebar/rel' ==> rel (generate) {"init terminating in do_boot","Release mynode uses non existing application mynode"} Crash dump was written to: erl_crash.dump init terminating in do_boot (Release mynode uses non existing application mynode) ``` I get a similar error when following https://bitbucket.org/basho/rebar/wiki/ReleaseHandling. When following http://www.metabrew.com/article/erlang-rebar-tutorial-generating-releases-upgrades, I get: ``` {"init terminating in do_boot…

Accepted Answer

I also started to learn erlang + rebar and I had the same problem some time ago and I suppose you have problem in your `reltool.config` file

- Add path to `lib_dirs`. I have `{lib_dirs, ["../../", "../deps/"]}`

- Add your app to app list. In my case this is - `{app, MY_APP_NAME, [{incl_cond, include}]}`

Update: You have to rename you app. F.e. to erlangtest1. My working reltool.config

```
{sys, [  
       {lib_dirs, ["../../"]},  
       {erts, [{mod_cond, derived}, {app_file, strip}]},  
       {app_file, strip},  
       {rel, "exemplar", "1",  
        [  
         kernel,  
         stdlib,  
         sasl,  
     erlangtest1  
        ]},  
       {rel, "start_clean", "",  
        [  
         kernel,  
         stdlib  
        ]},  
       {boot_rel, "exemplar"},  
       {profile, embedded},  
       {incl_cond, exclude},  
       {excl_archive_filters, [".*"]}, %% Do not archive built libs  
       {excl_sys_filters, ["^bin/.*", "^erts.*/bin/(dialyzer|typer)",  
                           "^erts.*/(doc|info|include|lib|man|src)"]},  
       {excl_app_filters, ["\.gitignore"]},  
       {app, sasl,   [{incl_cond, include}]},  
       {app, stdlib, [{incl_cond, include}]},  
       {app, kernel, [{incl_cond, include}]},  
       {app, erlangtest1, [{incl_cond, include}]}  
      ]}.

{target_dir, "exemplar"}.

{overlay, [  
           {mkdir, "log/sasl"},  
           {copy, "files/erl", "\{\{erts_vsn\}\}/bin/erl"},  
           {copy, "files/nodetool", "\{\{erts_vsn\}\}/bin/nodetool"},  
           {copy, "files/exemplar", "bin/exemplar"},  
           {copy, "files/exemplar.cmd", "bin/exemplar.cmd"},  
           {copy, "files/start_erl.cmd", "bin/start_erl.cmd"},  
           {copy, "files/install_upgrade.escript", "bin/install_upgrade.escript"},  
           {copy, "files/sys.config", "releases/\{\{rel_vsn\}\}/sys.config"},  
           {copy, "files/vm.args", "releases/\{\{rel_vsn\}\}/vm.args"}  
          ]}.  
```
