The fix in
NUTCH-873 introduces an unknown variable to the build process. Since local ivy artifacts are unversioned, different people that install Gora jars at different points in time will use the same artifact id but in fact the artifacts (jars) will differ because they will come from different revisions of Gora sources. Therefore Nutch builds based on the same svn rev. won't be repeatable across different environments.
As much as it pains the ivy purists until Gora publishes versioned artifacts I'd like to revert the fix in
NUTCH-873 and add again Gora jars built from a known external rev. We can add a README that contains commit id from Gora.
