I've recently changed my Eclipse e4 applications project configuration from being based on plug-ins to features. The application runs correctly but when exporting I get errors to do with a build.xml file.

After searching around I've found a couple of similar questions to do with this. To fix it people were installing/updating PDE. I've tried reinstalling it but it hasn't made a difference. Also I'm quite sure it is installed correctly as when the project configuration was based on plug-ins it would get the whole way through the build process.

Product File features

Problem Occurred error

What could be causing this?

Takin answered 6/3, 2019 at 10:58 Comment(8)
Looks like some sort of recursion in the PDE generated build.xml causing the stack to overflow. What is in your feature.xml and the xxx.product file? – Pillage
@Greg I've added information for the features.xml and product file features. Is there any other information that would be useful? – Takin
Build problems are extremely difficult to debug remotely. feature.name in your plug-in list doesn't look right. It is simpler to use features in the 'requires' list rather than specific plugins. – Pillage
That is a good point. feature.name is not a plug-in so it shouldn't be there and could mean things are stuck in an infinite loop? The problem is that if I don't have it there it says The following problems were detected: feature.name is missing. when I run the application. – Takin
I've found this that looks similar although they've produced it with different steps. bugs.eclipse.org/bugs/show_bug.cgi?id=335670 I've not got Generate metadata repository selected as that option doesn't exist though. – Takin
The option is called 'Generate p2 repository' these days. – Pillage
Yeah I thought it might be. I've tried switching all the options around to no avail. You mentioned above about a requires list. Where is this? I've found Required Features/Plug-ins but if I try adding feature.name it can't find it. I can add my other features successfully though. – Takin
The <requires> xml tag is called Dependencies in the feature.xml editor – Pillage

For me the solution was to put the product file to another plug-in product.
