[erlang-questions] Trouble with abstract code, cover and rebar3

The error message says the invalid chunk is the "Abst" chunk.

Maybe try checking out if the chunk can be read manually?

beam_lib:chunks("/home/vlad/projects/erlide_kernel/common/
_build/test/lib/erlide_tools/ebin/ttbe.beam", ["Abst"]).


And also:

beam_lib:chunks("/home/vlad/projects/erlide_kernel/common/
_build/test/lib/erlide_tools/ebin/ttbe.beam", [abstract_code]).


And if you are running on OTP 20:

beam_lib:chunks("/home/vlad/projects/erlide_kernel/common/
_build/test/lib/erlide_tools/ebin/ttbe.beam", [debug_info]).
