Eclipse上的Nutch错误tika.TikaParser

Question

I am running Nutch 2.2.1 on Eclipse Juno SR1 and JRE 1.7.0_25

The PARSE step is failing with this error:

2013-08-15 19:35:26,555 ERROR tika.TikaParser - Can't retrieve Tika parser for mime-type application/pdf
2013-08-15 19:35:26,557 WARN  parse.ParseUtil - Unable to successfully parse content

It seems like this error is coming from TikaConfig.java because I get an empty iterator:

Iterator<Parser> iterator = ServiceRegistry.lookupProviders(
    Parser.class, this.getClass().getClassLoader());

The same PARSE call from CYGWIN is successful, I get all PARSERS from Service registry. So maybe the solution is configuration for Eclipse related to Service registry.

Nutch-Eclipse is well configured about nutch-site.xml, parse-plugins.xml

I appreciate any idea to solve this.
