Answer 1

(The formatting of the errors in the question is a little messed up and hard to read, if you could correct that great!)
Make sure you have all the dependencies you need. In particular the error says you don't have javax.annotation.
This is the part of the error message:
ENTRY org.eclipse.core.runtime 4 0 2015-12-30 15:23:00.627 !MESSAGE FrameworkEvent ERROR !STACK 0 org.osgi.framework.BundleException: Could not resolve module: org.eclipse.core.runtime 2 Unresolved requirement: Require-Bundle: javax.annotation; bundle-version="1.1.0"; visibility:="reexport"; resolution:="optional" Unresolved requirement: Require-Bundle: javax.inject; bundle-version="1.0.0"; visibility:="reexport"; resolution:="optional" Unresolved requirement: Require-Bundle: org.eclipse.core.jobs; bundle-version="[3.2.0,4.0.0)"; visibility:="reexport"
This is what the error message probably looked like on your machine (formatting wise, not detail wise):
!ENTRY org.eclipse.ui 4 0 2015-12-30 14:16:58.931
!MESSAGE FrameworkEvent ERROR

Therefore, check if javax.annotation is included in the launch configuration, or if you are exporting the product before the failure, ensure it is in the dependency chain of your .product file.
