29 # Builds one JAR used by jtreg to test value classes (JEP 401):
30 #
31 #  valueClassPlugin.jar -- Contains ValueClassPlugin (a javac Plugin that
32 #    rewrites @AsValueClass classes to value classes at parse time) together
33 #    with @AsValueClass and the META-INF service descriptor, compiled WITH
34 #    --enable-preview and the required internal-API exports.
35 #
36 # Usage in test runs (via RunTests.gmk):
37 #   make test TEST=... JTREG=VALUE_CLASS_PLUGIN=true
38 #
39 # The plugin is also enabled automatically when --enable-preview is passed via
40 # VM_OPTIONS or JAVA_OPTIONS and the plugin JARs are present in the test image:
41 #   make test TEST=... JTREG=VM_OPTIONS=--enable-preview
