Exception while trying to configure the launcher #141

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1.Go to Debug Run configurations...
2.Create a Jetty Webapp launch configuration
3.See exception "Items models shouldn't be null".  Update LCD.
4.The dialog isn't shown

This leads the plugin to unusable.

Detailed exception:
java.lang.IllegalStateException: Items model shouldn't be null

It happens when we try to fetch the classpaths of Web project and Jetty 
classpath.

Not sure what's going on but there might be a environemnt issue, 
I  will add some logging code for more information when this bug shows up in 
next version.

Is there a known workaround for this bug? I have not yet been able to get past 
this issue (Jetty and this plugin are currently unusable).

My suggestion is to try the latest nightly version and see if it's still 
reproducible.

I had the same problem. The nightly version works better.
It does not cause an exception but reports that the current project does not 
exist.
This way I figured out that the project needs to be a Dynamic Web Project 
(Right click on project -> Configure -> Convert to Dynamic Web Project). Then 
it works just fine.

Completely removing the project and /or the plugin and / or the plugin folder 
and replacing does not fix this. What to need to do to purge all the 
run-jetty-run settings that are causing this to come back?

I get this error if I close a project which has a run-jetty-run launch 
configuration which means I can't configure any other launch configurations, 
even those not using run-jetty-run. I have to delete the run-jetty-run launch 
configurations which is painful because I don't want to have to recreate them 
later. Or I have to make sure to never close a project which has a 
run-jetty-run launch configuration, which defeats the purpose of being able to 
close projects in the first place.
