I use the binary distribution, so I don't know if this is the *right*
way to do this, but this may get you going until someone can respond
with an authoritative answer:
After you've downloaded and built Jena, there are lots of jars scattered about:
taylorj@kamja:~/Downloads/jena-2.10.1$ find . -iname "*.jar"
./jena-core/target/jena-core-2.10.1-javadoc.jar
./jena-core/target/jena-core-2.10.1-test-sources.jar
...
./jena-iri/target/jena-iri-0.9.6-sources.jar
./jena-iri/target/jena-iri-0.9.6-javadoc.jar
./jena-iri/target/jena-iri-0.9.6.jar
If, under the apache-jena directory, you make a lib directory and put
the jars there, and use the arq binary that in apache-jena/bin, you'll
be all set:
taylorj@kamja:~/Downloads/jena-2.10.1$ mkdir apache-jena/lib
taylorj@kamja:~/Downloads/jena-2.10.1$ find . -iname "*.jar" -exec cp
\{\} ./apache-jena/lib/ \;
You'll get a bunch of warnings there when it tries to copy from
apache-jena/lib into apache-jena/lib, but that's just because I didn't
write a better find that would exclude from searching there. Now you
should be able to run arq:
taylorj@kamja:~/Downloads/jena-2.10.1$ ./apache-jena/bin/arq
No query string or query file
taylorj@kamja:~/Downloads/jena-2.10.1$ ./apache-jena/bin/arq --data
~/.../data.n3 --query ~/.../subquery.sparql
