Subject [jira] [Updated] (AVRO-877) Support compiling multiple input schemas and protocols
Date Fri, 19 Aug 2011 18:12:28 GMT

]

Bill Graham updated AVRO-877:
-----------------------------

    Description: 
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}
