Vaadin UpdateTheme compiler failed with status 1 at org.codehaus.mojo.gwt.

I am working with a custom vaadin theme  and as of yesterday the compilation has started failing due to the local widgetset being detected as a network file.  Moved it to the C drive for the compile  and still get the same error

[INFO] auto discovered modules [com......bridger.alertmanager.gwt.AlertmanagerWidgetset]
[DEBUG] GWT module com.,,,,.bridger.alertmanager.gwt.AlertmanagerWidgetset found in C:\tmp\src\main\java

[INFO] Widgetsets found from classpath:
[INFO]     com.ejt.vaadin.loginform.WidgetSet in jar:file: D:/m2_repo/org/vaadin/addons/loginform/0.6.2/loginform-0.6.2.jar!/
[INFO]     org.vaadin.teemu.switchui.SwitchComponentWidgetset in jar:file: D:/m2_repo/org/vaadin/teemu/switch/2.0.2/switch-2.0.2.jar!/
[INFO]     com......bridger.alertmanager.gwt.AlertmanagerWidgetset in file://C/tmp/src/main/java
[INFO]     com.vaadin.DefaultWidgetSet in jar:file: D :/m2_repo/com/vaadin/vaadin-client/7.7.1/vaadin-client-7.7.1.jar!/

It is reading the file from the local drive as a network file and failing.
Using Vaadin 7.7.3 with Java 8 

Any help will be greatly appreciated.
