I can confirm what was said in the original discussion. The error occurs in fact in the tests calls System.exit() at some point. Reproducing is pretty simple: create a test that calls System.exit(). In my case it was a Spock test, but in the original discussion, people reported the issue with jUnit. Here is a trace of the execution: $ gradle test :compileJava UP-TO-DATE :compileGroovy UP-TO-DATE :processResources UP-TO-DATE :classes UP-TO-DATE :compileTestJava UP-TO-DATE :compileTestGroovy UP-TO-DATE :processTestResources UP-TO-DATE :testClasses UP-TO-DATE :test Unexpected exception thrown. org.gradle.messaging.remote.internal.MessageIOException: Could not read message from '/0:0:0:0:0:0:0:1:55216'. at org.gradle.messaging.remote.internal.inet.SocketConnection.receive(SocketConnection.java:88) at org.gradle.messaging.remote.internal.hub.MessageHub$ConnectionReceive.run(MessageHub.java:230) at org.gradle.internal.concurrent.DefaultExecutorFactory$StoppableExecutorImpl$1.run(DefaultExecutorFactory.java:66) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:662) Caused by: com.esotericsoftware.kryo.KryoException: Buffer underflow. at com.esotericsoftware.kryo.io.Input.require(Input.java:162) at com.esotericsoftware.kryo.io.Input.readByte(Input.java:255) at org.gradle.messaging.remote.internal.hub.InterHubMessageSerializer$MessageReader.read(InterHubMessageSerializer.java:64) at org.gradle.messaging.remote.internal.hub.InterHubMessageSerializer$MessageReader.read(InterHubMessageSerializer.java:53) at org.gradle.messaging.remote.internal.inet.SocketConnection.receive(SocketConnection.java:83) ... 5 more :test FAILED |

Having encountered this several times, I should say that this is definitely a bug. This is not the expected behavior of System.exit(). At the very least, a different error message should be displayed. |

I agree with Ron. This is a very unintuitive error. I'm a new Gradle user, and I've been working on it for a few hours now until I finally found this bug report and associated discussion. Gradle needs a much better handling of this problem than reporting MessageIOException. |

I suggest re-open this issue. The error message isn't helpful at all and renders the test cases useless. |

I agree with Tao. The error message should be more detailed. |

This might be due to the following bug in the underlying library (note, at the time of this comment, it is still OPEN). |

I had this error come up because an assertion was triggered (failed). It's a very big time-waster for this case, because I found myself trying to figure out what was wrong with the build. ("Could not find matching test for pattern") ./gradlew -q -Dtest.single=JwstBlankJUnitTest RegressionTests:test FAILURE: Build failed with an exception.

This one is still an issue IMHO because when a test does a System.exit (we do that to kill our system tests in case of timeout/hanging), because of the error, the test report won't get generated and you loose the nice HTML output, the build statistics and so on. For instance on Jenkins it forces to look through the logs to findout what happened. |

We're finding the same thing, though more recent versions of Gradle handle this a little more gracefully, because it short circuits report generation there's no indication of the last test to be run: * What went wrong: Execution failed for task ':test'. > Process 'Gradle Test Executor 1' finished with non-zero exit value 255 * Try: Run with --info or --debug option to get more log output. *

manager to catch the exit check and throw an exception to find the cause; not suggesting this is a viable solution for Gradle itself, but at least we should be able to get at the details of the test that causes the failure.
System.setSecurityManager(new SecurityManager() {
@Override
public void checkPermission(Permission perm) {
}
@Override
public void checkPermission(Permission perm, Object context) {
}
@Override
public void checkExit(int status) {
String message = "System exit requested with error " + status;
throw new IllegalStateException(message);
}
});
