WSO2 Composite Application Project doesn't show any dependencies in the wizard

Question

I am aware that this is very similar to a question posted over a year ago:

WSO2 Composite Application Project doesn't show any dependency

I am also following the WSO2 tutorial. I have downloaded the 'and the kitchen sink' version of eclipse from WSO2 and EI.

I tried the suggested solution in that other thread (downloading various versions of P2). All of them failed because the components were older than the ones I already had installed.

My platform is Win 10.

I'd be happy to switch to oxygen (most recent version of eclipse - the WSO2 one is Mars 2) if that would help.

The 'artifact' project which you create as the previous step is empty except for a pom.xml file. So perhaps there are some missing steps?

Here's that POM:

Thanks and apologies again.
