Hi Rafael,

The easiest way to build the plugin will be to build all of Drill 1.18 Snapshot 
with the plugin included.

1. Grab master from GitHub.

2. Merge in Charle's PR branch.

3. mvn clean install -DskipTests

The above usually works for me. This process ensures that all the snapshot 
versions come from your own build.

Not sure how we started storing snapshot versions in a Maven repo. This causes 
issues. If you rebuild part of Drill, and have not built the other parts in 
more than a day, Maven helpfully downloads the snapshots from the repo, causing 
all kinds of chaos. (We should fix this.)

Once you do the build, you'll have a full Drill distribution, just like you'd 
download. You can use that distribution to run Drill with the plugin included.

There are other ways that also work; the above may be the simplest.


Thanks,
- Paul

 Hi Charles,

(1./2.)
I have not been able to build Drill, from either a full clone of your tagged 
http-storage branch or from the standard Drill 1.17 release. 
I've narrowed it down to some dependency problems from the POM. In particular, 
I run into issues here:

Downloading: 
https://repo.maven.apache.org/maven2/org/apache/apache/21/apache-21.pom

http://cwiki.apache.org/confluence/display/MAVEN/UnresolvableModelException

I think it has something to do with the fact that I normally resolve 
dependencies from our local Maven repo mirrors. We have no problems getting 
stuff from Maven Central and common places, but I am unfamiliar with 
conjars.org. I wonder if it is related to that?

(3./4.)
I tried putting the JAR into either jars/ or jars/3rdparty with the same error. 
I haven't gone down the dependency tree so I have not made and JARs of them, 
that could be a major thing I'm missing.

Yes this is still in a testing environment. I'm going to use your pre-built 
images for testing the REST endpoint, this is extremely helpful. If it works 
out I'll go back to trying to build it. Also, hoping that this will make its 
way into the next (1.18) release.

Best,
Rafael

Hi Rafael,
Glad you're getting some value from Drill.  Repackaging that directory as a 
truly pluggable jar is tricky.  A few questions:
1.  Did you copy the contrib/storage-http into its own folder and then do a 
build from that?
2.  Did it build successfully?
3.  Did you copy the JARs into your Drill jars/3rdparty folder?
4.  You'll also have to get JARs of any dependencies as well and copy them to 
the jars/3rdparty.  Have you done that?

I actually have a pre-built version of Drill with the storage-http plugin 
available here: https://github.com/cgivre/drill/releases 
<https://github.com/cgivre/drill/releases>.  Please do not use that in any kind 
of production setup.  If you're just wanting to try this out, it might be 
easier to d/l that and use that.
