Cannot install in development mode

See original GitHub issue

Hi,

I am new to Pyserini. I followed steps in https://github.com/castorini/pyserini#development-installation to try to install this package in development mode (to try out DPR retrieval model), but I got java.lang.NoClassDefFoundError error when running unit test:

======================================================================
ERROR: tests.test_querybuilder (unittest.loader._FailedTest)
