Stephen Sisk commented on BEAM-2460:
------------------------------------
With a bit more investigation, I've landed on the following solution:
We will copy the groovy-maven-plugin invocation into the poms that need it, and
use project.parent.parent.[...].basedir to create a path that points at
findSupportedPython.groovy
So for the jdbc pom, this looks like:
<plugin>
<groupId>org.codehaus.gmaven</groupId>
<artifactId>groovy-maven-plugin</artifactId>
<version>${groovy-maven-plugin.version}</version>
<executions>
<execution>
<id>find-supported-python-for-compile</id>
<phase>initialize</phase>
<goals>
<goal>execute</goal>
</goals>
<configuration>
<source>${project.parent.parent.parent.parent.basedir}/sdks/python/findSupportedPython.groovy</source>
</configuration>
</execution>
</executions>
</plugin>
Where the project.parent.parent.parent... is specific to the directory that
it's in.
Conveniently, this will be the same for all the poms, so copy-pasting it will
work seamlessly with the io poms. I won't say I'm a big fan of this solution,
but given the alternatives, this seems like the least horrible one.

> We're planning to start using perfkit to make it easy for users to run the IO
> ITs. Perfkit is a python app, so we'll need to invoke the python interpreter.
> findSupportedPython calculates this and sets the python.interpreter.bin
> variable. It currently does so in the python project.
> I believe the correct answer here is to move findSupportedPython so that's
> it's invoked in the root pom. (but perhaps there's a more maven-y approach to
> this problem?)
