I'm now using the following for GWT in our build.gradle files.
I've remove the gwtVersion from the gwt block and switched to using
gwtSdk to specify the GWT version.
Really not sure why it keeps getting overridden from dependencies, I
would have thought that pulling in gwt-dev would have Gradle pull in the
newer version automatically. Is this possibly a bug with the plugin?
I have explicitly specified the htmlunit dependency to get superdev mode
to working again.
plugins {
id"java" id"war" id"org.docstr.gwt" id"org.gretty" }
dependencies {
gwtSdk'org.gwtproject:gwt-user:2.10.0' gwtSdk'org.gwtproject:gwt-dev:2.10.0' providedCompile"net.sourceforge.htmlunit:htmlunit:2.55.0" // to get superdev mode
working }

My apologies, I didn't notice your attachment until I had already hit
send. Checking the list shows that gwt-materialdesign is bringing in
an old version of htmlunit (GWT 2.10.0 updated this also), which is in
turn bringing in some old jetty versions:

I can't speak to how your Gradle setup is configured, but I think you
should have an explicit compile dependency on gwt-dev:2.10.0, which
should at least force jetty-io and htmlunit to be updated to the
expected versions.

Your stack trace lines up except for the top frame - jetty-io
9.4.4.v20210927 has a blank line for SelectorManager.java:81, and
the source for the file at that version doesn't contain the string
"No selectors". On the other hand, jetty-io 9.2.14.v20151116 has
this as a constructor (and line 81 is where it throws):
protected SelectorManager(Executor executor, Scheduler
scheduler, int selectors)
{
if (selectors<=0)
throw new IllegalArgumentException("No selectors");
this.executor = executor;
this.scheduler = scheduler;
_selectors = new ManagedSelector[selectors];
}
This much older version of jetty-io is the general version of
Jetty that GWT 2.9 used (as well as a few earlier GWT versions).
My guess is that you have correctly updated GWT, and the expected
version of Jetty has been updated (9.4.44), except somehow you
have a dependency on the old version of jetty-io. Check the rest
of your classpath, or the particular gradle plugin you are using?

Meh,
I've managed to break my GWT setup again. This time for
superdev mode. Looking for suggestions on where the (I assume)
Jetty conflict is coming from.
Getting the following stacktrace after "Module setup
