XMPP binding leads to ClassNotFoundException with current appengine-api-1.0-sdk:1.9.89

[leonard84]

It seems that google has removed the XMPPServiceFactory and other xmpp releated classes.
https://cloud.google.com/appengine/docs/standard/java/javadoc/deprecated-list

This leads to a ClassNotFoundException in the GaelykBindingEnhancer when running the code with the current com.google.appengine:appengine-api-1.0-sdk:1.9.89.

An easy fix would be to remove the lines in groovyx.gaelyk.GaelykBindingEnhancer

        // New in GAE SDK 1.2.5: XMPP support
        binding.setVariable("xmpp", XMPPServiceFactory.XMPPService)

or at least wrap them in a try-catch.

@leonard84 I guess this is an issue for Spock Web Console? @glaforge were you dealing with something similar? maybe now is the time to migrate to Micronaut Console ?

[leonard84]

This is going a bit off-topic, but yes I ran into it while updating the spock web console for 2.0.

@musketyr does GAE support running micronaut/netty now? #225 said this was an issue back then.
Also, does micronaut console offer any isolation/security support, a quick look in the docs didn't show anything?

The current implementation is quite open, but even if you kill it with System.exit(0) it comes back in 1-2 seconds.

[musketyr]

Things changed a lot since than. @glaforge would know more because I've totally lost the track with the Google Cloud ecosystem.

here's the article from him I have found:

https://glaforge.appspot.com/article/getting-started-with-micronaut-on-google-app-engine-java-11

Of course, you can reuse and attach your own compilation customizers:
