I am deploying a custom Portlet in Liferay, yet I did not see it in Portlet "Add".
I noticed in log that it missed the "Available for use" line. (Log in attachement)
"Deploying"->"Copied successfully"->"Available for use"????->"Started"

You seem to deploy a WAR style portlet. Check liferay-display.xml if your portlet is in category.hidden. In this case: Guess where it will be shown

You also seem to have some timezone mismatch - I hope that everything is packaged correctly and not marked as already current. Try to identify your computer's time and your personal timezone settings, so that those messages go away. The build process might not correctly identify out-of-date-resources, thus deploy them incorrectly.
