I am working on a Java project with Eclipse. This project requires a second project (not mine), named sams in its build-path. The sams is provided with a build.xml file and it should generate some code using Apache CXF when building it. When I use Apache ANT on Eclipse and run the cxf.generated command from its build file I get the following error:

Buildfile: C:\Docs\ZacRocha\Desktop\sams\build.xml
cxf.generated:

BUILD SUCCESSFUL

I am used to program on Eclipse and I know very little about building with Apache ANT. Can someone tell me where exactly the problem may be? Thanks in advance!
