[BAHIR-38] clean Ivy cache during Maven install phase
[BAHIR-38: Spark-submit does not use latest locally installed Bahir
packages](https://issues.apache.org/jira/browse/BAHIR-38)
When we `install` the org.apache.bahir jars into the local Maven repository
we also need to clean the previous jar files from the Ivy cache
(~/iv2/cache/org.apache.bahir/*) so `spark-submit -packages ...` will pick up
the new version from the the local Maven repository.
*pom.xml:*
```xml
<build>
<plugins>
...
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-clean-plugin</artifactId>
<executions>

>
> Key: BAHIR-38
> URL: https://issues.apache.org/jira/browse/BAHIR-38
> Project: Bahir
> Issue Type: Bug
> Components: Build
> Affects Versions: 2.0.0
> Environment: Maven (3.3.9) on Mac OS X
> Reporter: Christian Kadner
> Assignee: Christian Kadner
> Original Estimate: 4h
> Remaining Estimate: 4h
>
> We use {{`spark-submit --packages <maven-coordinates> ...`}} to run Spark
> with any of the Bahir extensions.
> In order to perform a _manual integration test_ of a Bahir code change
> developers have to _build_ the respective Bahir module and then _install_ it
> into their *local Maven repository*. Then, when running {{`spark-submit
> --packages <maven-coordinates> ...`}} Spark will use *Ivy* to resolve the
> given _maven-coordinates_ in order add the necessary jar files to the
> classpath.
> The first time Ivy encounters new maven coordinates, it will download them
> from the local or remote Maven repository. All consecutive times Ivy will
> just use the previously cached jar files based on group ID, artifact ID and
> version, but irrespective of creation time stamp.
> This behavior is fine when using spark-submit with released versions of Spark
> packages. For continuous development and integration-testing however that Ivy
> caching behavior poses a problem.
> To *work around* it developers have to *clear the local Ivy cache* each time
> they _install_ a new version of a Bahir package into their local Maven
> repository and before the run spark-submit.
> For example, to test a code change in module streaming-mqtt, we would have to
> do ...
> {code}
> mvn clean install -pl streaming-mqtt
> rm -rf ~/.ivy2/cache/org.apache.bahir/spark-streaming-mqtt_2.11/
> ${SPARK_HOME}/bin/spark-submit \
> --packages org.apache.bahir:spark-streaming-mqtt_2.11:2.0.0-SNAPSHOT \
> test.py
> {code}
