: Can you try "ant compile example"? : After Lucene/Solr merge, solr ant build needs to compile before example : target.
the "compile" target is already in the dependency tree for the "example" target, so that won't change anything. At the moment, the "nightly" snapshots produced by hudson only iclude the "solr" section of the "dev" tree -- not modules or the lucene-java sections . The compiled versions of thothat code is included, so you can *run* solr from the hudson artifacts, but aparently you can't compile it. (this is particularly odd since the nightlies include all the compiled lucene code as jars in a "lucene-libs/" directory, but the build system doesn't seem to use that directory ... at least not when compiling solrj). This is all side effects of trunk still being somewhat in transition -- there are kinks in dealing with the artifacts of the nightly build process tha still need worked out, -- but if your goal is to compile things yourself, then you might as well just check out the entire trunk and use that compile fro mthat anyway. -Hoss
