Facing issue while creating mahout-core.jsr
Hi ,
I have downloaded Mahout zip.
My JDK version id 1.5.0
Maven 2.1.0
Do Mahout Taste don't work with JDK1.5?
>From where can i find mahout-core.jar?
I try to create Mahout-core.jar with mv install as suggested on site.
I get below error. what could be root cause of this?

You can compile using 1.6, but set the compatibility level to 1.5 in pom.xml. Then you will be able to *run* it with 1.5. You'll also need to comment out a few lines in 1-2 classes that use 1.6 APIs. Here are the files I modified locally in order to be able to compile with 1.6 and run with 1.5:
M core/src/main/java/org/apache/mahout/classifier/bayes/BayesClassifier.java
M core/src/main/java/org/apache/mahout/classifier/cbayes/CBayesClassifier.java
M core/pom.xml

You do need 1.6. I also am unsure about Mvn 2.1.0 vs 2.0.10. I have
seen some reports that 2.1.0 doesn't work with Mahout due to plugin
incompatibility, but please report back.
Once you have that in place, do mvn install at the top level.
