Google Cloud Platform – How to Download File from Artifact Registry (Maven)

Based on Apache Buildr code : http://svn.apache.org/repos/asf/buildr/trunk/lib/buildr/packaging/artifact.rb

You can do something like this:

def snapshot?
  version =~ /-SNAPSHOT$/
end

if snapshot?
    metadata_path = "#{group_path}/#{id}/#{version}/maven-metadata.xml"
    metadata_xml = StringIO.new
    URI.download repo_url + metadata_path, metadata_xml
    metadata = REXML::Document.new(metadata_xml.string).root
    timestamp = REXML::XPath.first(metadata, '//timestamp')
    build_number = REXML::XPath.first(metadata, '//buildNumber')
    snapshot_of = version[0, version.size - 9]
    classifier_snippet = (classifier != nil) ? "-#{classifier}" : ""
    repo_url + "#{group_path}/#{id}/#{version}/#{id}-#{snapshot_of}-#{timestamp.text}-#{build_number.text}#{classifier_snippet}.#{type}"
end

Have you installed RStudio in a Linux VM? If so you can ssh into your instance using command sudo gcloud compute ssh <your-instance-name> --zone <your-instance-zone> and then use wget from inside your instance to download the file:

wget https://www.kaggle.com/c/5174/download/Images_1.zip

wget might get disconnected during the download but you can use options described in above link that will help you make the download successful, like the -t and -c options for trying the download more times or continue getting a partially-downloaded file, respectively.

After the file is downloaded you can use 7ZIP to unzip the file in the directory where it was downloaded to using the command: 7z e Images_1.zip
You can copy the file to a GCP bucket using the command:
gsutil cp Images_1 gs://<your-bucket-name>

If wget and 7zip are not installed in the VM you can install them as per instructions, wget and 7zip, as follows. This examples are for Ubuntu or Debian Linux VMs:

sudo apt-get update
sudo apt-get install wget
sudo apt-get install p7zip-full

Just follow installation instructions.
