Problems with Erlang version 21. The current ct are only executed under version 22, 23.

[WoelkiM]

Possible bench implementation:

- name: Checkout repo bench
  uses: actions/checkout@v2
  with:
    repository: riak-core-lite/rcl_bench
    path: ./rcl_bench/

- name: start bench
  run: |
    cd rclref
    make devrel 
    make devrel-start
    make devrel-join
    make devrel-cluster-plan
    make devrel-cluster-commit
    cd ../rcl_bench
    make run

Problem: {error, "Incomplete form (missing .)??"}; See: (rotaki/rclref#6)

at some point doing rpc eval calls to a node from the command line changed from requiring a dot at the end to not requiring it, maybe in 21 the dot is required?

This is quite possible, but for me the error occurred with Erlang version 23. I will check how it behaves under 21.

edit: The error message under Erlang 21:
escript: exception error: undefined function rebar3:main/1
in function escript:run/2 (escript.erl, line 758)
in call from escript:start/1 (escript.erl, line 277)
in call from init:start_em/1
in call from init:do_boot/3

When running make devrel the problem is that in github actions unfortunately an error occurs.
example commit link(my fork): "connect rcl_bench Erlang CI #43" (Erlang 23)
"mkdir -p _build/dev3/rel/rclref/../rclref_config
/__w/_temp/1c3e05fd-8a1d-4484-a65b-7277e1c164b5.sh: 2: /__w/_temp/1c3e05fd-8a1d-4484-a65b-7277e1c164b5.sh: : not found"

This error did not occur in the previous executions and I can't understand why it occurs now. My thoughts are that either connections are no longer there or old files/processes are not terminated correctly. Unfortunately I haven't found a solution yet.

We add a new issue for rcl_bench and close this one.
