Try this and see if it works Open the build.xml file and the add env JAVA_HOME in compile-core-native target.

HDFS and libhfds
hello there, im trying to compile libhdfs in order but there are some problems. According to http://wiki.apache.org/hadoop/MountableHDFS i have already installes fuse. With ant compile-c++-libhdfs -Dlibhdfs=1 the buils is successful. However when i try ant package -Djava5.home=... -Dforrest.home=... the build fails and the output is the below : [exec] [exec] Exception in thread "main" java.lang.UnsupportedClassVersionError: Bad version number in .class file [exec] at java.lang.ClassLoader.defineClass1(Native Method) [exec] at java.lang.ClassLoader.defineClass(ClassLoader.java:620) [exec] at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:124) [exec] at java.net.URLClassLoader.defineClass(URLClassLoader.java:260) [exec] at java.net.URLClassLoader.access$100(URLClassLoader.java:56) [exec] at java.net.URLClassLoader$1.run(URLClassLoader.java:195) [exec] at java.security.AccessController.doPrivileged(Native Method) [exec] at java.net.URLClassLoader.findClass(URLClassLoader.java:188) [exec] at java.lang.ClassLoader.loadClass(ClassLoader.java:306) [exec] at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:268) [exec] at java.lang.ClassLoader.loadClass(ClassLoader.java:251) [exec] at org.apache.avalon.excalibur.logger.DefaultLogTargetFactoryManager.configure(DefaultLogTargetFactoryManager.java:113) [exec] at org.apache.avalon.framework.container.ContainerUtil.configure(ContainerUtil.java:201) [exec] at org.apache.avalon.excalibur.logger.LogKitLoggerManager.setupTargetFactoryManager(LogKitLoggerManager.java:436) [exec] at org.apache.avalon.excalibur.logger.LogKitLoggerManager.configure(LogKitLoggerManager.java:400) [exec] at org.apache.avalon.framework.container.ContainerUtil.configure(ContainerUtil.java:201) [exec] at org.apache.cocoon.core.CoreUtil.initLogger(CoreUtil.java:607) [exec] at org.apache.cocoon.core.CoreUtil.init(CoreUtil.java:169) [exec] at org.apache.cocoon.core.CoreUtil.(CoreUtil.java:115) [exec] at org.apache.cocoon.bean.CocoonWrapper.initialize(CocoonWrapper.java:128) [exec] at org.apache.cocoon.bean.CocoonBean.initialize(CocoonBean.java:97) [exec] at org.apache.cocoon.Main.main(Main.java:310) [exec] Java Result: 1 [exec] [exec] Copying broken links file to site root.
