Running the bin/nutch crawl command with Cygwin
Hello,
Using: Nutch 0.9
I'm trying to run the bin/nutch command using cygwin. The message I
receive is:
Chargement de la classe java impossible.
java.lang.UnsupportedClassVersionError:
org/apache/hadoop/util/PlatformName (Unsupported major.minor version
49.0)
Chargement de la classe java impossible.
java.lang.UnsupportedClassVersionError: org/apache/nutch/crawl/Crawl
(Unsupported major.minor version 49.0)
When I check my version of Java using the jkava -version command:
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_09-b03)
My JAVA_HOME is equal to:
/cygdrive/c/path/to/Java1.5
Any idea?
Thank you and a happy new year to everybody?
David

You were right Martin...
By pointing the $NUTCH_JAVA_HOME variable to the correct JDK, using cygWin, everything worked perfectly!
Bizarre that my redefinition of $JAVA_HOME, locally inside my cygWin session, didn't worked...
Thanks a lot!

Hi,
"major.minor version 49.0" indicates that the bytecode is for a Java
1.5 or later. The error (should) mean the code is being loaded by a vm
pre-1.5.
Do you have (somewhere) a JRE on your machine which is pre-1.5?
If you just type "java" on the command-line windows (and cygwin
respectively) will execute a java.exe which is located in
"WINDOWS/system32".
What happens if you type (in cygwin) "$JAVA_HOME/bin/java -version"?
You can try to define a variable NUTCH_JAVA_HOME, which overrides
JAVA_HOME (nutch will use NUTCH_J_H instead of JAVA_HOME).
Greetings,
Martin
