2013 SR2 – Errors building Android or iOS apps

If you have installed some third party plugins (specifically those which include version 1.6.0 of the com.google.gson bundle) into MyEclipse 2013 SR2, you could see the following error when attempting to build your applications.

No-args constructor for class com.genuitec.mobioneappsync.api.DesignUploadResponse does not exist. Register an InstanceCreator with Gson for this type to fix this problem.

As a possible fix until an update is released, please edit the ini file in the root of your installation folder (myeclipse.ini / myeclipse-blue.ini / myeclipseforspring.ini) and on the second line, before the -startup switch, add -clean, so the first few lines of your ini file would look like

#utf8 (do not remove)
-clean
-startup
...

This will fix the workbench initialization to ensure that our build infrastructure uses a more recent version of the gson plugin and you should no longer see this error. Due to the non-deterministic nature of the problem there is a small chance that the above steps do not fix your problem, we will be releasing an update to make this unnecessary.

I would like to reiterate that the problem may occur only on MyEclipse installations with specific third party plugins installed, most plugin installations will not cause this problem nor will this occur with stock MyEclipse 2013 installations.
