Subject Re: build hadoop-2.4.1 by mvn eclipse:eclipse fail in mac os x 10.9

Hi Li Li,

This is happening because Hadoop expects classes.jar to be in a location
which no longer exists on Java 7 on Mac.

Below steps will fix it,
$ mkdir -p
 /Library/Java/JavaVirtualMachines/jdk1.7.0_65.jdk/Contents/Home/Classes/
$ cd !$
$ ln -s
/Library/Java/JavaVirtualMachines/jdk1.7.0_65.jdk/Contents/Home/lib/tools.jar
classes.jar


Thanks,
Mahesh
