What diagnostic action to take when Maven hangs ?
Hi,
I have a Maven build that hangs and I wonder what to do to get some feedback
like a message or stack trace or dump..
I'm stuck trying to run some integration tests
http://forum.springsource.org/showthread.php?130859-Maven-build-hangs-on-simple-Roo-script&p=426888&posted=1#post426888
Thanks
Stephane

From the original post, it appears that the hang is in the testing
phase so I am not sure how much information will come out in a dump or
Maven debug mode but it will not hurt anything.
I am more suspicious about a test with a loop that does not terminate or
a test with a set of bad credentials or a bad URL that is causing a
remote operation or database access to fail and go into a wait state.

Did you try Ctrl+\ (or Ctrl+Pause on Windows) from the console to do a full
thread dump? It might shed some light on what is going on. You can also run
Maven in debug mode ("mvn -X") to potentially get more information about
where things hang.

Adding some logging to the tests would help.
In Windows, you can use Task Manager to see what your processes are doing.
In Linux, top will tell you.

Not Ctrl-C. Use Ctrl+\ (Linux/Mac/etc.) or Ctrl+Pause (Windows).

Hello,
How can I find out if it is CPU or OI bound ?
It hangs before the very first test.
The test is an integration test, connecting to a MySql database schema.
For now my test is very simple:
@RooIntegrationTest(entity = Address.class)
public class AddressIntegrationTest {
@Before
public void beforeAnyTest() throws Exception {
}
@After
public void afterAnyTest() throws Exception {
}
@Test
@Transactional
public void testSaveAndRetrieve() {
AddressDataOnDemand dod = new AddressDataOnDemand();
Address address = dod.getRandomAddress();
assertNotNull(address.getId());
Integer version = address.getVersion();
addressRepository.saveAndFlush(address);
assertTrue(version != address.getVersion());
}
}
Doing a Ctrl-C gives me back the prompt but I don't see any console output
like a dump.
This test is within a Spring Roo application.
I also created a pure Spring application last year, not a Roo one, with lots
of integration tests against a Dao layer on the very same MySql database
schema. And this Maven project builds fine. But not the Roo one.

What is it doing when it hangs.
It is CPU bound, IO bound or waiting for roo to access a database or
remote service?
On which test is it hanging?
What does that test do?
Do you have lots of debug statements in your tests?
Just some ideas to think about.
