Sandbox script is not able to install bundle due to empty $BRANCH value

[gsmendoza]

Solidus Version

Should be master branch, but the sandbox script is setting it to an empty string:

# Gemfile
gem 'solidus', github: 'solidusio/solidus', branch: ''

To Reproduce

Run bin/sandbox on repo's master branch (f99f81f).

Current behavior

At the point when the sandbox script tries to install the Solidus gem, the following error is displayed:

Furthermore, if you cd to the sandbox and run bundle install, you get the same error:

Expected behavior

bin/sandbox should be able to install solidus.

Possible cause

The Solidus branch specified in the Gemfile is an empty string:

# sandbox/Gemfile
gem 'solidus', github: 'solidusio/solidus', branch: ''

Possible solution

By default, the solidus branch should be set to master:

# sandbox/Gemfile
gem 'solidus', github: 'solidusio/solidus', branch: 'master'

It seems that copying these two fixes from SolidusDevSupport would fix this issue:

• solidusio/solidus_dev_support@ef20862
