Ralf commented on NUTCH-2512:
-----------------------------
I just compiled master/trunk on a VM-Box with Ubuntu Bionic and Oracle Java
10.1 - It trows a couple of warnings, but compiles and I have it doing a small
crawl right now and so far so good. Nutch now no longer takes the Solr url from
the commandline, this should be reflected in the tutorials and docs by the time
1.15 gets released. (I still can't compile Nutch with Tika 1.18 on my Java 8
set-up, it works when I revert to Tika 1.17, I wonder what could be wrong with
my Java set-up)
