# This eclass provides functionality which is used by
# java-pkg.eclass and java-pkg-opt.eclass as well as from ebuilds.
#
# @warning
# You probably don't want to inherit this directly from an ebuild. Instead,
# you should inherit java-ant for Ant-based Java packages, java-pkg for other
# Java packages, or java-pkg-opt for packages that have optional Java support.

# Ebuild can specify this variable before inheriting java-ant-2 eclass to
# determine ANT_TASKS it needs. They will be automatically translated to
# DEPEND variable and ANT_TASKS variable. JAVA_PKG_FORCE_ANT_TASKS can override
# ANT_TASKS set by WANT_ANT_TASKS, but not the DEPEND due to caching.
# Ebuilds that need to depend conditionally on certain tasks and specify them
# differently for different eant calls can't use this simplified approach.
# You also cannot specify version or anything else than ant-*.

# @variable-external JAVA_PKG_WANT_SOURCE

# at build time and are not needed on runtime (junit testing etc).
#
# Example: get all jars from xerces slot 2
# java-pkg_jar-from xerces-2
# Example: get a specific jar from xerces slot 2
# java-pkg_jar-from xerces-2 xml-apis.jar
# Example: get a specific jar from xerces slot 2, and name it diffrently

# Example: get junit.jar which is needed only for building
# java-pkg_jar-from --build-only junit junit.jar
#
# @param $opt
# --build-only - makes the jar(s) not added into package.env DEPEND line.
# (assumed automatically when called inside src_test)
# --with-dependencies - get jars also from requested package's dependencies
# transitively.
# --virtual - Packages passed to this function are to be handled as virtuals
# and will not have individual jar dependencies recorded.
# --into $dir - symlink jar(s) into $dir (must exist) instead of .
# @param $1 - Package to get jars from, or comma-separated list of packages in
# case other parameters are not used.
# @param $2 - jar from package. If not specified, all jars will be used.
# @param $3 - When a single jar is specified, destination filename of the
# symlink. Defaults to the name of the jar.
