From the outsystems support:
we did a review to the possible error associated with this plugin, it seems that it uses a dependency with the same name used by the OutSystems shell. To enable a proper compilation, it was necessary to create a fork of the plugin where it doesn't use the same dependency.
You should be able to compile your OutSystems mobile application by using the following plugin version: https://github.com/vmfo22/wikitude-cordova-plugin
