Yes - look in the apache-jena area for a freshly built distribution
(under target/ and in your local maven repo).
If you just want the latest development codebase built, that happens
automatically each "night" (actually about 8am UTC - the build system is
less busy then):
https://repository.apache.org/content/repositories/snapshots/org/apache/jena/apache-jena/
so you can pick up a binary distribution for the commands from there.
This includes all the scripts.
If you are changing the source, you'll need to build it.
Each module can be built on it's own, in which case "mvn clean install"
will put the new jar into target/jena-MODULE.jar and place it in your
local repo.

If you want the commands, you want an unpacked binary distribution. The
scripts are in bin/* and they automatically set the environment root JENA
https://jena.apache.org/documentation/tools/index.html
The environment variable, if you need to set it, is JENAROOT.
ARQROOT is to using the development area of ARQ alone and from Eclipse.
You want to look in the apache-jena module where there is a binary
distribution.
There is another set of scripts in jena-arq/bin: these are for working
with the development system e.g. under Eclipse. These are sensitive to
class folders. They are also a bit fragile because they assume the
Eclipse setup.
One trick is to use the Fuseki server jar. This is a complete system in
a single jar. It is the only thing you need on the classpath.
java -cp fuseki-server.jar arq.sparql ....
will run the command. The Fuseki server jar includes core jena, ARQ,
TDB, and all their dependencies.

Hi, this is probably a "stupid question", but I have no experience with
Maven and very little with Java, so I'm quite stuck right now. I have Maven
3.0.5 installed, and here's what I've tried to install arq:
cd $HOME/dev
wget http://www.apache.org/dist/jena/source/jena-2.10.1-source-release.zip
unzip jena-2.10.1-source-release.zip
cd jena-2.10.1
mvn install
Builds fine and tests run fine. Here's a complete log:

After taking a look at the arq bin file, I tried
java -cp jena-core/target/classes:jena-arq/target/classes: arq.arq
but then I just got another NoClassDefFoundError for
"org/apache/log4j/PropertyConfigurator" instead. I didn't manage to find
that class. Could there be some path I have not set (correctly)?
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
