I'm running into the following build error upon trying to ant standalone the xwiki trunk along with gdata jars and my classes for google docs: [javac] /tmp/clover50747.tmp/src50748.tmp/com/xpn/xwiki/gwt/api/client/GdataAttachmentListInteraction.java:10: generics are not supported in -source 1.4 [javac] (try -source 1.5 to enable generics) [javac] private Map<String, ListEntry> entriesCached; [javac] ^ [javac] 1 error Sergiu hinted that it's because of Java 1.4 (Gdata needs at least 1.5). How do I get over this? Also, what modifications should i make to pom.xml in order to add some jars to the project? (gdata api jars - originally sources, that have to be built into jars) Thanks for your time, Radu Danciu
