Hi, I want to test my custom es plugin (6.4.0) every time I run `gradle test`, this error occurs. ```auto Exception thrown by subscriber method onHeartbeat(com.carrotsearch.ant.tasks.junit4.events.aggregated.HeartBeatEvent) on subscriber com.carrotsearch.gradle.junit4.TestProgressLogger@437b66e when dispatching event: com.carrotsearch.ant.tasks.junit4.events.aggregated.HeartBeatEvent@593ec899 java.lang.NullPointerException: Cannot get property 'className' on null object at org.codehaus.groovy.runtime.NullObject.getProperty(NullObject.java:60) at org.codehaus.groovy.runtime.InvokerHelper.getProperty(InvokerHelper.java:174) at org.codehaus.groovy.runtime.callsite.NullCallSite.getProperty(NullCallSite.java:47) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.callGetProperty(AbstractCallSite.java:296) at com.carrotsearch.gradle.junit4.TestProgressLogger.onHeartbeat(TestProgressLogger.groovy:161) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:564) at com.carrotsearch.ant.tasks.junit4.dependencies.com.google.common.eventbus.Subscriber.invokeSubscriberMethod(Subscriber.java:95) at com.carrotsearch.ant.tasks.junit4.dependencies.com.google.common.eventbus.Subscriber$SynchronizedSubscriber.invokeSubscriberMethod(Subscriber.java:154) at com.carrotsearch.ant.tasks.junit4.dependencies.com.google.common.eventbus.Subscriber$1.run(Subscriber.java:80) at com.carrotsearch.ant.tasks.junit4.dependencies.com.google.common.util.concurrent.MoreExecutors$DirectExecutor.execute(MoreExecutors.java:456) at com.carrotsearch.ant.tasks.junit4.dependencies.com.google.common.eventbus.Subscriber.dispatchEvent(Subscriber.java:76) at com.carrotsearch.ant.tasks.junit4.dependencies.com.google.common.eventbus.Dispatcher$PerThreadQueuedDispatcher.dispatch(Dispatcher.java:119) at com.carrotsearch.ant.tasks.junit4.dependencies.com.google.common.eventbus.EventBus.post(EventBus.java:215) at com.carrotsearch.ant.tasks.junit4.events.aggregated.AggregatingListener.slowHeartBeat(AggregatingListener.java:76) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:564) at com.carrotsearch.ant.tasks.junit4.dependencies.com.google.common.eventbus.Subscriber.invokeSubscriberMethod(Subscriber.java:95) at com.carrotsearch.ant.tasks.junit4.dependencies.com.google.common.eventbus.Subscriber$SynchronizedSubscriber.invokeSubscriberMethod(Subscriber.java:154) at com.carrotsearch.ant.tasks.junit4.dependencies.com.google.common.eventbus.Subscriber$1.run(Subscriber.java:80) at com.carrotsearch.ant.tasks.junit4.dependencies.com.google.common.util.concurrent.MoreExecutors$DirectExecutor.execute(MoreExecutors.java:456) at com.carrotsearch.ant.tasks.junit4.dependencies.com.google.common.eventbus.Subscriber.dispatchEvent(Subscriber.java:76) at com.carrotsearch.ant.tasks.junit4.dependencies.com.google.common.eventbus.Dispatcher$PerThreadQueuedDispatcher.dispatch(Dispatcher.java:119) at com.carrotsearch.ant.tasks.junit4.dependencies.com.google.common.eventbus.EventBus.post(EventBus.java:215) at com.carrotsearch.ant.tasks.junit4.LocalSlaveStreamHandler$3.run(LocalSlaveStreamHandler.java:149) ``` Tests succeed. but I want to remove this errors. +++++ Here is my environment. ```auto Gradle Version : 4.9 OS Info : Mac OS X 10.12.6 (x86_64) JDK Version : Oracle Corporation 10.0.2 [OpenJDK 64-Bit Server VM 10.0.2+13] JAVA_HOME : /Users/user/.sdkman/candidates/java/10.0.2-open ``` ---

What do your tests look like? Are they all using junit? The class name comes back from the JUnit description of the class that randomized runner gets programmatically. ---

Hi, Here is my test. ```auto public class PluginEnvironmentTests extends ESTestCase { public void testGetPluginSettings() { // given Setting clusterName = new Setting<>("plugin.cluster.name", s -> "elasticsearch", Function.identity(), Setting.Property.NodeScope); PluginEnvironment environment = new PluginEnvironment(clusterName); // when List> PluginSettings = environment.getPluginSettings(); // then assertEquals(PluginSettings.size(), 15); assertEquals(PluginSettings.get(0), environment.getClusterName()); assertEquals(PluginSettings.get(1), environment.getInterval()); assertEquals(PluginSettings.get(2), environment.getEnabled()); assertEquals(PluginSettings.get(3), environment.getHosts()); ... } } ``` ---

What does your classpath look like? ---

I copied my test class path. ```auto ${projectRoot}/src/test/java/${myPackagePath}/PluginEnvironmentTests.java ``` and I do not set special `classpath` var anywhere. ---

I'm not sure what you mean by that being your classpath. The classpath should contain jar files, not a java file. You need to include all the jars that are dependencies of the elasticsearch test framework jar. ---

Now I understand what you mean. Thanks for your help. I solved my issue. I added the test framework jar in my build script. ---
