# We provide two ways to build maven based ebuilds.
# The first is with maven itself
# The second is via generated build.xml by the maven-ant plugin
# to control how to handle it there is two variables
# JAVA_MAVEN_BUILD_SYSTEM :
# possibles values:
# 	eant:  if set use any generated build.xml found.
# 	maven; if set use maven as the builder : TODO implement
#
# For multi projects you can use JAVA_MAVEN_PROJECTS which is a space separated
# list of inner modules to build in a maven multiproject based build.
# Remember to generate all necessary build.xml.
# Normally, doing mvn ant:ant on the parent project is suffisant.
#
# If the generated build.xml doesn't fit to your needs,
# you can use your own build.xml to compile and assembly
# sources by placing it in ${FILESDIR}/build-${PV}.xml.
# eg: doesn't contain any javac target but some is needed,

# For javadoc generation and source bundling,
# you can set JAVA_MAVEN_SRC_DIRS as a comma sepated
# list of java source directories and add "doc" and
# "source" uses in IUSE.
