Re: Eclipse Error
Let's keep the discussion in the User mailing list.
I would suggest you to follow the instructions here to set up Nutch in
Eclipse [1]
JDK 1.6 + or 1.7 + will be good enough. I would also suggest to keep your
JRE compatible with the JDK.

Re: Eclipse Error
Posted by Lewis John Mcgibbney <le...@gmail.com>.
We compile and test Apache Nutch on Solaris with the Java 7 (latest) JDK
and all is good. I run Apache Nutch on some CI ubuntu servers. I do not run
on Windows. This may be a problem, or it could be your development
environment, or it could be something else.
I have not engaged in this conversation before, so I can only assume it is
something to do with your local environment.

Re: Eclipse Error
Posted by Danilo Fernandes <da...@kelsorfernandes.com.br>.
Thanks for the reply Tejas, but I tried run by ant many times and
do not have any difference.
About turning on verbose level for ivy, I´m
a nuts with Eclipse and plugins.
Can you help me do that?

Re: Eclipse Error
Posted by Tejas Patil <te...@gmail.com>.
Hi Lewis,
The OP is not able to build nutch in Eclipse. So far people have been
suspecting over this part of the log:
**C:\Users\Danilo\workspace\Nutch\build.xml:96:
java.lang.UnsupportedClassVersionError: com/sun/tools/javac/Main :
Unsupported major.minor version 51.0*****
*
It turns out that the java version is fine. (v 1.6). I am not sure but this
problem might be related to ivy as per this error:
*> > [*ivy:resolve*] unknown resolver main*****
*> > [*ivy:resolve*] :: USE VERBOSE OR DEBUG MESSAGE LEVEL FOR MORE
> > DETAILS****
*
I had faced this error before but it was sporadic and used to go away after
invoking ant again. OP faces it consistently.
@Danilo: Maybe turning on verbose level for ivy might shed some light.
Thanks,
Tejas Patil

Let's keep the discussion in the User mailing list.
I would suggest you to follow the instructions here to set up Nutch in
Eclipse [1]
JDK 1.6 + or 1.7 + will be good enough. I would also suggest to keep your
JRE compatible with the JDK.
