## Class AntlrTask

- java.lang.Object
- - org.gradle.api.internal.AbstractTask
  - - org.gradle.api.DefaultTask
    - - org.gradle.api.internal.ConventionTask
      - - org.gradle.api.tasks.SourceTask
        - - org.gradle.api.plugins.antlr.AntlrTask

- All Implemented Interfaces:
    Comparable<Task>, org.gradle.api.internal.DynamicObjectAware, org.gradle.api.internal.IConventionAware, org.gradle.api.internal.TaskInternal, ExtensionAware, Task, PatternFilterable, org.gradle.util.Configurable<Task>

      public class AntlrTask
      extends SourceTask

  Generates parsers from Antlr grammars.

  Most properties here are self-evident, but I wanted to highlight one in particular: `setAntlrClasspath(org.gradle.api.file.FileCollection)` is used to define the classpath that should be passed along to the Ant `ANTLR` task as its classpath. That is the classpath it uses to perform generation execution. This should really only require the antlr jar. In `AntlrPlugin` usage, this would happen simply by adding your antlr jar into the 'antlr' dependency configuration created and exposed by the `AntlrPlugin` itself.
