Help on using vaultclipse in eclipse lunar for aem

We are trying to use vaultclipse plugin on an Apple using OS X version 10.10.1

We can import the vault clipse plugin into Eclipse Lunar. In Lunar we used the following steps to re-install vaultclipse

Try
1. Uninstall VaultClipse
2. Install "Eclipse 2.0 Style Plugin Support"[*]
3. Install VaultClipse

[*]
1. Go to Help->Install New Software
2. Choose "The Eclipse Project Updates - http://download.eclipse.org/eclipse/updates/4.4" in "Work with" combo
3. Select "Eclipse 2.0 Style Plugin Support" under "Eclipse Tests, Examples, and Extras"
4. Go ahead

However, when we try configure vaultclipse preferences we get an error.

We point the vault directory field to an instance of filevault inside of AEM and it gives an error on saving that the filevault directory is invalid.

We then took one of the compressed folders with file vault from crx-quickstart and extracte it in to a folder off of root. We then pointed the vaultclipse plugin preferences to the extracted filevault and get the same error.

When replicated the above steps on a Windows machine using Eclipse Kepler they all worked.
