Usage

You have to define the location of schema json generated by room. You can do so by adding following block.

 roomUpgrade {
    jsonPath YourSchemaPath (e.g. "$projectDir/schemas")
 }

Room will add json schema every time you upgrade your database models and DB version.

This plugin will read those json files, find out the difference and will show you the queries you have to run in your migration grouped by each upgrade from version to version.

To get these queries, you have to run getStatements task added by this plugin.
