Doug Cutting commented on AVRO-877:
-----------------------------------
We might just run the compiler over some inputs and check that the expected
output files are created. So a test case would be a list of input files (in
the src/ tree) and the list of expected files that will be created (in the
target/ tree).
For extra credit we could compile these output files to check them with javac.

Another approach is like TestIdl, where the compiler output is also in the test
tree, and we check the generated output against that.

> With AVRO-872, multiple inter-dependent schema files can be parsed.
> {{SpecificCompilerTool}} should be changed to allow the same when producing
> java from multiple schemas or protocols. Proposed syntax change is to allow
> multiple files or directories to be passed (space-delimited) before the last
> token, which is the output path.
> - To compile multiple files where {{b}} depends on {{a}}:
> {noformat}
> $ java -cp avro-tools-x.x.x.jar org.apache.avro.tool.Main \
> compile schema input/a.avsc input/b.avsc output
> {noformat}
> - To compile files from multiple directories:
> {noformat}
> $ java -cp avro-tools-x.x.x.jar org.apache.avro.tool.Main \
> compile schema input1 input2 output
> {noformat}
> - To compile {{b}} which depends on {{a}} and all the other content in
> {{input}} that might depend on {{a}} or {{b}}:
> {noformat}
> $ java -cp avro-tools-x.x.x.jar org.apache.avro.tool.Main \
> compile schema input/a.avsc input/b.avsc input output
> {noformat}
