Not fixed for me... https://gist.github.com/lpgauth/8dce1737056c89737410

@lpgauth are you using any plugins other than the erlydtl plugin? do you have any other beam files that are produced outside the built in rebar3 build chain?

[lpgauth]

No beams from the outside.

Plugins:

{plugins, [
  {pc, ".*",
    {git, "https://github.com/blt/port_compiler.git", {branch, "master"}}},
  {rebar3_eqc, ".*",
    {git, "https://github.com/kellymclaughlin/rebar3-eqc-plugin.git", {tag, "0.0.8"}}},
  {rebar3_erlydtl_plugin, ".*",
    {git, "https://github.com/lpgauth/rebar3_erlydtl_plugin.git", {branch, adgear}}}
]}.

@lpgauth i'm unable to reproduce. could you rm -rf _build and try again with latest head? if you still see the failure i'd like to talk to you about trying to reduce this to a test case so i can try to figure out what is going on. there's an explicit guard against exactly the failure you're seeing in the cover provider so something must be calling cover:compile outside the normal code path

[lpgauth]

Ok, I dig a little bit and it seems more a cover problem then rebar3. I'll open a pull req upstream.
