# Builds one JAR used by jtreg to test value classes (JEP 401):
#
#  valueClassPlugin.jar -- Contains ValueClassPlugin (a javac Plugin that
#    rewrites @AsValueClass classes to value classes at parse time) together
#    with @AsValueClass and the META-INF service descriptor, compiled WITH
#    --enable-preview and the required internal-API exports.
#
# Usage in test runs (via RunTests.gmk):
#   make test TEST=... JTREG=VALUE_CLASS_PLUGIN=true
#
# The plugin is also enabled automatically when --enable-preview is passed via
# VM_OPTIONS or JAVA_OPTIONS and the plugin JARs are present in the test image:
#   make test TEST=... JTREG=VM_OPTIONS=--enable-preview
