[antlr-interest] Compiling Java source files when using the antlr3-maven-plugin

[Jim Idle]

Did you add the package statement to the @arser and @lexer header sections? The output files will generated I the correct place, but you need to add the package yourself, just like in Java.

 

Your best bet is to start here:

and modify the sample project that is produced.

Subject: [antlr-interest] Compiling Java source files when using the antlr3-maven-plugin

 

Hello, 

 

I have a simple maven project with source files configured as follows:

 

my_project/

    - pom.xml

    - src

        - main

            - antlr3

                - my_package

                    - MyGrammar.g

            - java

                - my_package

                    - MyClass.java

 

 

When I execute mvn compile my parser and lexer sources are generated properly and reside under target/generated-sources as expected.  However, MyClass.java is not compiled and the process gives me the following error:

 

...

target/generated-sources/antlr3/my_package/MyParser.java:[105,13] cannot find symbol

symbol  : constructor MyClass()

 ...

 

Any help would be greatly appreciated.

 

Cameron.
