We are currently finalizing the documentation for importing and building Mobione apps inside the MyEclipse IDE. The current process will allow users to build their projects using the PhoneGap Build service as well as perform local builds if they have the respective mobile SDKs installed on their systems.
Our intention has been to provide the upcoming MyEclipse 2015 as a replacement for the aging App Center Build services. Unfortunately we have been delayed as the MyEclipse 2015 release date was extended in order to provide additional key improvements in the web, javascript and phonegap tooling. MyEclipse 2015 development versions have been released approximately every 4-6 weeks. We expect the next development version planned for late next week to provide the level of tooling to support building MobiOne projects with in MyEclipse. And soon after that time we will have an initial process on how to build your Mobione apps with MyEclipse. We will update this post with information and links as they are released.
