#28 Invalid zip file

[Gorkem ERCAN]

eclipse.buildId=M20100909-0800
java.version=1.6.0_20
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=linux, ARCH=x86, WS=gtk, NL=en_US
When I first add the floggy nature to my project eclipse fails that the floggy-persistence-framework-impl.jar is an invalid zip file. When I check I see that this zip file does not have any content in it.

Framework arguments: -product org.eclipse.epp.package.pulsar.product
Command-line arguments: -os linux -ws gtk -arch x86 -product org.eclipse.epp.package.pulsar.product

Noticed that this is actually happening because floggy builder fails to resolve classes that are used from other eclipse projects.
