Building Signed APK of Javafx application with GluonFX plugin

Question

I am using HelloFX project from gluon-samples repository. I've used a keystore (which was generated for a different project) and tried to build APK of this app.

COMPILE TASK and LINK TASK completed successfully. But PACKAGE TASK failed with following log message.

</manifest>

Why does this issue occur and how to fix this?

And another doubt, does current version of gluonfx plugin use files under /target folder or the files under actual project while building APK?
