PostHeaderIcon Jetty / Timeout scanning annotations

Case

My application consists in a WAR I deploy on Tomcat or Jetty during the development phase. I execute Eclipse Jetty either in standalone, or via Maven Jetty plugin – most of the time.

On updating and deploying the application on my laptop (which is not my primary development machine), I get the following error with Maven:

java.lang.Exception: Timeout scanning annotations

Unlike, with a standalone instance of Jetty, the WAR is successfully deployed.

Explanation

Since the release of 9.1 branch, Jetty server limits the scan time for annotations at 60 seconds, by default.
The exception is raised here: source

boolean timeout = !latch.await(getMaxScanWait(context), TimeUnit.SECONDS);
          
        if (LOG.isDebugEnabled())
        {
            for (ParserTask p:_parserTasks)
                LOG.debug("Scanned {} in {}ms", p.getResource(), TimeUnit.MILLISECONDS.convert(p.getStatistic().getElapsed(), TimeUnit.NANOSECONDS));

            LOG.debug("Scanned {} container path jars, {} WEB-INF/lib jars, {} WEB-INF/classes dirs in {}ms for context {}",
                    _containerPathStats.getTotal(), _webInfLibStats.getTotal(), _webInfClassesStats.getTotal(),
                    (TimeUnit.MILLISECONDS.convert(System.nanoTime()-start, TimeUnit.NANOSECONDS)),
                    context);
        }

        if (timeout)
            me.add(new Exception("Timeout scanning annotations"));

Fix

As a quick fix, on launching Maven, add the option -Dorg.eclipse.jetty.annotations.maxWait=120 (set a higher value if needed):

mvn jetty:run -Dorg.eclipse.jetty.annotations.maxWait=120

You can also set this property directly in jetty-*.xml configuration files, for webapp or even for a complete server.
