-I file cp -v -p file --target-directory=/bakup/iscsi/mp3

Adding NTFS Write support on Mac OS X

Resolved: javac: invalid target release: 1.6

javac: invalid target release: 1.6 :
Recently I ran into this while compiling some stuff through Maven. My development environment is Mac OS X(10.5), Eclipse (3.5), Maven (2.0.9), Java (1.6)
I tried some suggestions through Google but they didn’t help me. Finally resolved the isse. Follow this steps:

• Check if JAVA_HOME is set
• Check if PATH is set & it’s pointing to same Java version
• Now another important thing – Run mvn –version, check if the Java version matches.

(Mac Users)If do this:
Check your CurrentJDK path defined under "/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK".
That is most likely the culprit. Maven script uses this symlink value.

You are hopefully done 🙂

[javac] class file has wrong version 50.0, should be 49.0
Somehow on my Mac (10.5) I ran into this issue with Eclipse (3.5) and Nutch (1.0). It seems this was causing because of the incompatible version of Java Compiler.

Solution: Check your project settings & make sure your Java compiler version & installed JRE are pointing to the correct version. By default it points to JRE 1.5. After you update these references everything should work like a charm 🙂
