Matt Goldspink commented on IVYDE-133:
--------------------------------------

I hit this error this morning when starting up Eclipse with 2.0.0.beta1. I =
don't think the statement: "When launching Eclipse, and if there are some f=
ailing resolve job" is correct because the code in the IvyClasspathContaine=
rConfiguration.setConfStatus() method says:=20

            if (e !=3D null) {
                setResolveStatus(new Status(IStatus.ERROR, IvyPlugin.ID, IS=
tatus.ERROR, e
                        .getMessage(), e.getCause()));
            } else {
                setResolveStatus(Status.OK_STATUS); <!--- So it sets the st=
atus when its ok
            }

I did a bit of debugging and it looks like the line:

           IvyPlugin.getDefault().getContainerDecorator().statusChaged(this=
);

throws the null pointer and its because the call to getContainerDecoractor(=
) is returning null. The reason is because Eclipse hasn't yet initialized t=
hat part of the plugin because none of the projects are expanded yet. Is it=
 possible to just add a simple check to change the above line to be:

           IvyClasspathContainerDecorator decorator =3D IvyPlugin.getDefaul=
t().getContainerDecorator();
           if (decorator !=3D null) {
                    decorator.statusChaged(this);
           }
