Simple Ruby gem to download/publish arbitrary binary file from/to Nexus server


Add this line to your application's Gemfile:

gem 'nexus_artifact'

And then execute:

$ bundle

Or install it yourself as:

$ gem install nexus_artifact


Create a nexus.yml file specifying location of artifact in nexus server:

:uri:      http://my-maven-server:8081
:path:     /nexus/content/repositories/some-repo/com/some-company/some_artifact
:artifact: "%v/any_name.%v.%e"
:user:     someuser
:pass:     somepass

In ruby code:

# Publish the file
NexusArtifact.instance.publish '/source_dir/my_file.iso', :ver => '3.5.2', :ext => 'iso'

# Download the file
NexusArtifact.instance.get '/save_dir/my_file.iso', :ver => '3.5.2', :ext => 'iso'

With the nexus.yml file above, this will publish two files:

  1. http://my-maven-server:8081/nexus/content/repositories/some-repo/com/some-company/some_artifact/3.5.2/any_name.3.5.2.iso
  2. http://my-maven-server:8081/nexus/content/repositories/some-repo/com/some-company/some_artifact/3.5.2/any_name.3.5.2.iso.sha1

In addition, you can find out what versions are available as well as what the next availble build number is:

# Will return e.g. ['3.4.1', '3.4.2', '3.5.1', '4.8.12']

# Will return e.g. '4.8.13'

If you do not wish to use a nexus.yml file, you can also create an instance of this class:

artifact = 'http://my-maven-server:8081',
artifact.auth 'someuser', 'somepass' # Only if needed
