Here you can find a step by step to start working on Swift.
Enjoy!
- File > New > Other > Maven Project
- Check on “Create a simple project (skip archetype selection)”
- Set the following properties
| Group Id | Artifact Id | Version |
|---|---|---|
| org.openstack | openstack-swift-demo | 0.0.1-SNAPSHOT |
Edit your pom.xml (it should look similar to the one below)
