Hi,
as I was investigating an apparent performance regression in tdbquery
(see my recent posts to the users list) I noticed that it's pretty
difficult to run the Jena command line tools from a development
environment. It's possible that I'm missing something obvious here, but
I think this has been a problem for others as well and at some point in
2015-2016 a fix was in place, but it's no longer working.
The problem is that the scripts expect a single directory with all the
relevant JARs that can be used as the classpath. But when building Jena,
the various JARs will be all around the directory tree. They get
collected into the .zip/.tar.gz packages though. So the easiest way to
run the scripts is to extract one of those archives. But that's a bit
cumbersome, it would be easier if one could run them straight after
building the source.
Apparently Rob noticed this while working on JENA-977 way back in 2015
and added a section to apache-jena/pom.xml that copied all the necessary
JARs to apache-jena/lib (commit 3c59213e273). This was further refined
by JENA-1173 - the problem was that the lib/ directory got included into
the source release zip files, so this added another section into
apache-jena/pom.xml to clean up the lib/ directory.
So far so good - I think at this point the mechanism was working so it
was easy to run the scripts from a dev environment (I didn't test this
though).
But then came commit a9701d2706a (by Andy in 2016) where the main
objective appears to be omitting javadocs, but the relevant sections in
the pom.xml were also commented out (and an obvious typo within that
section was corrected as well).
So we're now back to square one, and it's again hard to run the scripts
from a dev environment as there is no single lib/ directory that would
hold all the JARs.
As I said I may have missed something obvious. What is the recommended
way of running, say, tdbquery or riot, after just having built Jena?
