# Inherit this bbclass for each java recipe that builds a Java library (jar file[s]).
#
# It automatically adds important build dependencies, defines JPN (Java Package Name)
# a package named ${JPN} whose contents are those of ${datadir}/java (the jar location).
#
# The JPN is basically lib${PN}-java but takes care of the fact that ${PN} already
# starts with "lib" and/or ends with "-java". In case the "lib" prefix is part of
# your package's normal name (e.g. liberator) the guessing is wrong and you have
# to set JPN manually!
#
# package archs are set to all, if the recipe builds also packages which
# can not be used for all archs, then set the PACKAGE_ARCH of that package
# manually *before* inheriting the class, see rxtx_xx.bb for an example.
