Provides support for both automatic and # manual manipulation of build.xml files. Should be inherited after java-pkg-2 # or java-pkg-opt-2 eclass. inherit java-utils-2 multilib # This eclass provides functionality for Java packages which use # ant to build. In particular, it will attempt to fix build.xml files, so that # they use the appropriate 'target' and 'source' attributes. # @ECLASS-VARIABLE: WANT_ANT_TASKS # @DEFAULT_UNSET # @DESCRIPTION: # An $IFS separated list of ant tasks. # Ebuild can specify this variable before inheriting java-ant-2 eclass to # determine ANT_TASKS it needs. They will be automatically translated to # DEPEND variable and ANT_TASKS variable. JAVA_PKG_FORCE_ANT_TASKS can override # ANT_TASKS set by WANT_ANT_TASKS, but not the DEPEND due to caching. # Ebuilds that need to depend conditionally on certain tasks and specify them # differently for different eant calls can't use this simplified approach. # You also cannot specify version or anything else than ant-*. # # @CODE # WANT_ANT_TASKS="ant-junit ant-trax" # @CODE #The implementation of dependencies is handled by java-utils-2.eclass #WANT_ANT_TASKS # @ECLASS-VARIABLE: JAVA_ANT_DISABLE_ANT_CORE_DEP # @DEFAULT_UNSET # @DESCRIPTION: # Setting this variable non-empty before inheriting java-ant-2 disables adding # dev-java/ant-core into DEPEND. if [[ -z "${JAVA_ANT_DISABLE_ANT_CORE_DEP}" ]]; then JAVA_ANT_E_DEPEND+=" >=dev-java/ant-core-1.8.2" [[ "${EAPI:-0}" != 0 ]] && JAVA_ANT_E_DEPEND+=":0" fi # add ant tasks specified in WANT_ANT_TASKS to DEPEND local ANT_TASKS_DEPEND; ANT_TASKS_DEPEND="$(java-pkg_ant-tasks-depend)" # check that java-pkg_ant-tasks-depend didn't fail if [[ $? != 0 ]]; then eerror "${ANT_TASKS_DEPEND}" die "java-pkg_ant-tasks-depend() failed" fi # We need some tools from javatoolkit.
