running ANTLR from Eclipse???

[1wretch]

Has anyone tried to run the ANTLR generated code for a grammar from Eclipse?

I try to create a Java project from the ANTLR output folder but when I run it I get:

Exception in thread "main" java.lang.Error: Unresolved compilation problems:
ANTLRFileStream cannot be resolved to a type
CommonTokenStream cannot be resolved to a type
CommonTokenStream cannot be resolved to a type
The method prog() from the type RichExprParser refers to the missing type RecognitionException
RecognitionException cannot be resolved to a type

at __Test__.main(__Test__.java:11)

Did I install the ANTLR plugin completely, or do I need to specify additional ANTLR libraries somehow?
In my installed software tab for Eclipse I see:

org.antlr.ui 4.1.1 org.antlr.ui.feature.group
This feature is an user interface for the ANTLR
framework for constructing recognizers,
compilers, and translators ...(URL removed)...
It consists of five plugins, two hold the ANTLR binaries
and documentation, the others contain a compiler and
an editor for ANTLR grammar files, and the ANTLR XML Support plugin.

Add those libraries to the project you created where you want to use them in.

I am very new to Eclipse so I don't know my way around it yet. I tried:

project properties
Java Build Path
Libraries tab
Add Library

It asks what library type to add, but none of the types (JRE, JUnit, Plugin, User) list the ANTLR plugin?

The documentation for the plugin should explain how to use it.
