I am beginning to see where I am going wrong. I pulled down the sdb source
distribution and fuseki binary distribution. I am doing "mvn clean install"
in the jena-sdb-1.3.5 for example, and it does create jars in target, but
there is no lib dir etc. So in my setup, there are no distinct jars for
arq, core, etc.
Pulling down the jena-2.10.0 source distro, I see jena-sdb under it, but it
is commented out in the pom. Uncommenting it and building throws an
immediate error:
[ERROR] The project org.apache.jena:jena-sdb:1.3.6-SNAPSHOT
(/Users/***/Source/GraphIDS/jena-2.10.0/jena-sdb/pom.xml) has 1 error
[ERROR] Non-resolvable parent POM: Could not find artifact
org.apache.jena:jena-parent:pom:5-SNAPSHOT and 'parent.relativePath' points
at wrong local POM @ line 29, column 11 -> [Help 2]
Just bad timing - the code gets changed when the release happens but to
make it buildable with the whole of Jena (actually, just the parent
module), the SDB build names the release jena-parent.
The code can be ahead of the artifacts in the globally mirrored maven
repositories for 24 hours ... and one maven attempt to read and miss
causes maven by default to wait 24 hours before trying again giving a
window of 48 hours when the build is unstable.
Before I go trying to fix things that aren't broken, let me tell you what I
want to do. Working is a rather backwards manner, I jumped into the code
and created a patch to support a new database type, Redshift. It is modeled
off the postgresql stuff, but with the necessary changes to work on
Redshift. I can apply the patch cleanly to jena-sdb-1.3.5 and 1.3.6.
I built 1.3.6-SNAPSHOT to generate a jar, and I was able to load it up with
Fuseki and connect to my Redshift instance. However, I need to have the SDB
command line tools working as well, so I can create the schema etc. What
approach should I be taking to achieve my goal.
I appreciate the support, and hopefully I will have Redshift support to
contribute back as a result.
Good news!
