How to do common tasks

There are currently two package.xml format versions. The <package format="2"> is recommended for new development.

• Package format 2 (recommended)
  • Overview
  • Resolving dependencies
  • Building and installing targets
  • Configuring and running unit tests
  • Migrating from package format 1

The original <package format="1"> was used for most packages released to Groovy and Hydro. It is still fully supported and maintainers need not re-release their packages merely to upgrade the package version.

Use these instructions when making small changes to an existing format 1 package. Larger changes would justify migrating to format 2. Never mix versions in a single package.
