That's trivial. Just run ant in the plugin's source folder: cd src/plugin/urlnormalizer-basic/ ant
or to run also the tests cd src/plugin/urlnormalizer-basic/ ant test Note: you have to compile the core test classes first by running ant compile-core-test in the Nutch "root" folder. A little bit slower but guarantees that everything is compiled: ant -Dplugin=urlnormalizer-basic test-plugin Or sometimes it's enough to skip some of the long running tests: ant -Dtest.exclude='TestSegmentMerger*' clean runtime test Best, Sebastian On 05/04/2018 01:13 PM, Yash Thenuan Thenuan wrote: > Hi all, > I want to compile my plugins separately so that I need not compile > the whole project again when I make a change in some plugin.
