Rebar Jiffy dependency not available

Question

I'm trying to add davisp/jiffy as a rebar dependency in Ejabberd so I can do some JSON parsing in my modules. I found this tutorial, where they add Jiffy as a dependency for a different project, but it didn't work. I tweaked it a little to match how they import other dependencies in Ejabberd, and it still didn't work. This is what my Deps looks like in rebar.config.script:

Deps = [{p1_cache_tab, ".*", {git, "git://github.com/processone/cache_tab"}},
        {p1_tls, ".*", {git, "git://github.com/processone/tls"}},
        {p1_stringprep, ".*", {git, "git://github.com/processone/stringprep"}},
        {p1_xml, ".*", {git, "git://github.com/processone/xml"}},
        {esip, ".*", {git, "git://github.com/processone/p1_sip"}},
        {jiffy,   "0.*", {git, "git://github.com/davisp/jiffy"}},
        {p1_stun, ".*", {git, "git://github.com/processone/stun"}},
        {p1_yaml, ".*", {git, "git://github.com/processone/p1_yaml"}},
        {ehyperloglog, ".*", {git, "https://github.com/vaxelfel/eHyperLogLog.git"}},
        {p1_utils, ".*", {git, "git://github.com/processone/p1_utils"}}],

Output of calling make:

ejabberd@ubuntuserver:~/ejabberd$ make
/usr/lib/erlang/bin/escript rebar skip_deps=true compile
==> rel (compile)
==> avalanche (compile)
Dependency not available: jiffy-0.* ({git,"git://github.com/davisp/jiffy"})
ERROR: compile failed while processing /home/ejabberd/avalanche: rebar_abort
make: *** [src] Error 1

What am I doing wrong?

Answer 1

I don't know why, but make clean then make again made it work. I figured this out by making that Canillita thing from the tutorial and seeing that it had no problem with Jiffy, so I assumed it was because I was making it clean.
