alfresco-sdk: ClassNotFoundException running Integration Tests

+1. I’ve the same thing.

I am having the same problem, and it’s with an empty getting-started sample. The SDK 3.0.1 is NOT working out-of-the-box.

+1 - same thing (albeit with platform-jar-archetype).

I’m submitting a …

[x] bug report
[ ] feature request

Expected Behavior

No ClassNotFoundException should be thrown at the end of running integration tests.

Current Behavior

The following exceptions are thrown at the end of running integration tests: (see stack trace/log excerpt in “Additional information” section). Please also note that the build/goal is marked as “BUILD SUCCESS” and everything seems to be fine (i.e. the integration tests have been executed successfully).

Possible Solution

A first idea is that the mentioned classes are not available in the classpath when stopping the embedded tomcat / end of build lifecycle.

Steps to Reproduce (for bugs)

1. Create a new AIO Alfresco SDK 3 project.
2. Run “mvn verify” in the AIO project
3. Wait until the end
4. Check log messages

Context

Your Environment

The below command solved my problem mvn dependency:resolve

I can confirm that it is related to the JVM shutdown hooks not playing nicely with the maven lifecycle and classloading.

When I remove all shutdown hooks the exception messages are no longer displayed. 👍

This was tested by removing the shutdown hooks before the tests end. Removing those hooks is a bit of a hack:

private void removeShutdownHooks() throws ReflectiveOperationException {
    @SuppressWarnings("rawtypes")
    Class clazz = Class.forName("java.lang.ApplicationShutdownHooks");
    Field field = clazz.getDeclaredField("hooks");
    field.setAccessible(true);

    @SuppressWarnings("unchecked")
    Map<Thread, Thread> hooks = (Map<Thread, Thread>)field.get(null);
    hooks.clear();
}
