Gentoo Development

• If you write a simple ebuild, you still have to place it in the main Portage tree or in an overlay.

• Apparently you don't get the auto-resume feature automatically. Nor do you get MD5 verification.

General Ebuild development guide

• A list of important variables available when writing ebuilds:
  • {$S}: Path to the temporary build directory.
  • {$P}: Package name and version.

Java Ebuild writing guide

• Official Guide

• ANT_TASKS can be set (and should be set) manually on the ebuild, but only in src_compile() or src_test().

• The jar names should not contain version number, if you need to rename them, there is an eclass for that: java-pkg_newjar.

• If a package provides differents APIs, the package should be always SLOTed based on the version of the API.
