rebar3 compile silently fails

[catamorphism]

$ rebar3 compile
===> Fetching erequest_id
(tchevalier@tchevalier-ltm)
[Tue Jan 06~18:08:39] ~/heroku/hundur $ echo $?
1

The compile command failed, but didn't print a message indicating the failure. If I do this:

$ DEBUG=1 rebar3 compile

I get more info:

[snip]
===> Fetching erequest_id
===> sh info:
    cwd: "/Users/tchevalier/heroku/hundur"
    cmd: git clone https://github.com/heroku/erequest_id.git .tmp_dir193467206960 -b 0.2.1 --single-branch

failed with return code 128 and the following output:
Cloning into '.tmp_dir193467206960'...
fatal: could not read Username for 'https://github.com': Device not configured

Not sure what's going on here, but in any case, rebar3 should be reporting the failure without having to use DEBUG=1.

Damn, yea, terrible user experience. It is because you don't have github https support for private repos setup in your .netrc.

Will leave this ticket open until we have it provide a useful error message.

Once I fixed my .netrc:

$ rebar3 compile
===> Fetching erequest_id
===> Fetching midjan
===> Fetching dinerl
(tchevalier@tchevalier-ltm)
[Wed Jan 07~13:24:12] ~/heroku/hundur $ DEBUG=1 rebar3 compile

===> sh(git clone https://github.com/SemanticSugar/dinerl.git .tmp_dir393704963216 -b v1.0.1 --single-branch)

fatal: did not receive expected object 68f43be15accbd4403af68315c9ac997ad8e46cf

I'm pretty sure this is the same bug, since both issues involve git failing, but in different ways. Just thought I would document this other failure case too.

Hi catamorphism,
could you try modify the git config file, add the line below to see if fix the issue.
compression = -1

Here is the same symptom, but another way to resolve: http://git.661346.n2.nabble.com/Large-pack-causes-git-clone-failures-what-to-do-td5481488.html

Oh, we forgot to close this. @shijiang1130 it was a github issue. Thanks.

Closing this now even though I said I'd leave it open until I made error messages better, just to make it less confusing :)
