-----------------------------------
Summary: JMH incompatibility with latest gradle
version/configuration
Key: GEODE-5991
URL: https://issues.apache.org/jira/browse/GEODE-5991
Project: Geode
Issue Type: Bug
Components: build, tests
Reporter: Ryan McMahon
There appears to be some compatibility issues between our current gradle
version (4.10) and configuration, and the JMH gradle plugin
(me.champeau.gradle.jmh). It is not clear if it is a version incompatibility,
or if the plugin is misconfigured.
To reproduce, build Geode then run a single JMH test like so:
`./gradlew jmh -Pinclude=GetOnRegionBenchmark`
Next, make some change to the test file i.e. GetOnRegionBenchmark.java in this
example. For instance, remove the @WarmUp annotation from the benchmark
method. Then run the above .gradlew command again. It should fail with the
following (or similar) error. A workaround is to add the `--info` flag to the
command, which appears to force a flush of some cached state and allows the
test to build/run correctly.
