<!-- Wraps a JavaCC/JJTree task and adapts the generated sources to the PMD

codebase.
|
|
|
|
Input parameters:
|
|
|
|
- lang-name: Capitalized name of the language eg Jsp or Java.
|
|
By convention the grammar file must be named exactly
|
|
so with a .jj[t] extension.
|
|
- lang-terse-name: Terse name, used in the conventional package names
|
|
|
|
It also uses the following maven properties:
|
|
|
|
- javacc.outputDirectory: Directory in which to root the generated package tree
|
|
- javacc.jar: JAR of JavaCC in the local maven repository
|
|
- some properties of project.build
