------------------------------------------------------------------

IntelliJ Idea 2016.3.1 builds are broken by this change.  You must close your 
project and re-import the gradle build to fix the problem.  A workaround is to 
generate the absent source files with gradle.

IntelliJ Idea 2016.3.1 builds are broken by this change.  A workaround is to do 
a command-line build to have the generated-source files be created.

> The OQL engine currently uses antlr to generate some parsing classes from 
> gemfire-core/src/main/java/com/gemstone/gemfire/cache/query/internal/parse/oql.g
> These are the generated classes. They are currently checked into the source.
> OQLLexer.java
> OQLLexerTokenTypes.java
> OQLLexerTokenTypes.txt
> OQLParser.java
> They can be generated manually by running antlr.Tool on the provided grammar.
> cd gemfire-core/src/main/java/com/gemstone/gemfire/cache/query/internal/parse/
> java -cp antlr.jar antlr.Tool oql.g
> We should add support to the gradle build to generate these classes.
> In my opinion we should also remove the checked in classes. With gradle we 
> can configure things so that the gradle eclipse target will generate these 
> classes and make them available to the IDE as well. Look at 
> gemfire-core/build.gradle for how we do this with the version properties file:
> sourceSets {
>   main {
>     output.dir(generatedResources, builtBy: 'createVersionPropertiesFile')
>   }
> }
