About java directory under the tutorial

[chengzheng]

Hi

I was trying to build the java part under the tutorial example, but I got such 
error information.

localhost java # ant
Buildfile: /root/thrift-0.6.1/tutorial/java/build.xml

init:

compile:
    [javac] /root/thrift-0.6.1/tutorial/java/build.xml:44: warning: 
'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to 
false for repeatable builds
    [javac] Compiling 7 source files to /root/thrift-0.6.1/tutorial/java/build

BUILD FAILED
/root/thrift-0.6.1/tutorial/java/build.xml:44: 
/root/thrift-0.6.1/lib/java/build/ivy/lib does not exist.

Total time: 0 seconds

I did the same thing in 0.5.0 and it works. Can someone tell why I failed in 
0.6.1

Thanks

Cheng
