Improve pseudo-unique ct_run node name Replacing crypto:rand_uniform(0, 10000) with rebar_rnd:uniform(10000) (which is either rand:uniform or random:uniform dependent on what otp version it runs on) fails in rebar_ct. One might assume it's because the old call requests a number >= 0 while the new call has no way to ask for anything but >= 1. However, the way the value is used doesn't rely on it to include 0, so the bug lies elsewhere. Actually, generating a random number to choose a pseudo-unique ct_run node name isn't a reliable method to avoid naming clashes. I cannot reproduce it locally and also cannot see the actual error in the CI logs. Mirroring what rebar_eunit does and using a bigger rng range seems to be enough to avoid node name clashes on Travis-CI.
rebar is deprecated and will receive only bug fixes. We encourage you to move to rebar3.
rebar is an Erlang build tool that makes it easy to compile and test Erlang applications, port drivers and releases.
rebar is a self-contained Erlang script, so it's easy to distribute or even embed directly in a project. Where possible, rebar uses standard Erlang/OTP conventions for project structures, thus minimizing the amount of build configuration work. rebar also provides dependency management, enabling application writers to easily re-use common libraries from a variety of locations (git, hg, etc).
Information on building and installing Erlang/OTP can be found here (more info).
To build rebar you will need a working installation of Erlang R13B03 (or later).
Should you want to clone the rebar repository, you will also require git.
You can download a pre-built binary version of rebar from:
https://github.com/rebar/rebar/wiki/rebar
$ git clone git://github.com/rebar/rebar.git $ cd rebar $ ./bootstrap Recompile: src/getopt ... Recompile: src/rebar_utils ==> rebar (compile) Congratulations! You now have a self-contained script called "rebar" in your current working directory. Place this script anywhere in your path and you can use rebar to build OTP-compliant apps.
Please refer to CONTRIBUTING.
In case of problems that cannot be solved through documentation or examples, you may want to try to contact members of the community for help. The community is also where you want to go for questions about how to extend rebar, fill in bug reports, and so on.
The main place to go for questions is the rebar mailing list. If you need quick feedback, you can try the #rebar channel on irc.freenode.net. Be sure to check the wiki first, just to be sure you're not asking about things with well known answers.
For bug reports, roadmaps, and issues, visit the github issues page.
