> Currently, it looks like the only option to importing another schema in IDL is to place
the file being imported in the same directory as that of the importing avdl.  In a setup where
there are avdl's that are spread among several maven projects that are owned by different
teams, this is logistically difficult to manage.
> When using the avro-maven-plugin, I would like to be able to just create a dependency
from my project on another jar that contains the avdl I am want to import and have Avro be
smart enough to look for it in the classpath of the project containing the avdl when compiling
my avdl.
> Attached is a working patch that will:
>   1. Change the IDLProtocolMojo class to lookup the current project's classpath and create
a new ClassLoader.
>   2. Give the Idl compiler class the ClassLoader before parsing the avdl.
>   3. If the Idl class encounters an import that it cannot resolve to the local directory
while parsing, it will try to use the ClassLoader to load up the file being imported.
> The patch spans the Avro 1.6.1 tag of the Java avro, avro-compiler, and avro-maven-plugin
projects.
