> Hi team.
> I tried to resolve this issue in https://issues.apache.org/jira/browse/GROOVY-10886. But it was unsuccessful. The proposed 'GroovyShell' parser does not perform its functions.
> I tried to update Groovy for 4.0.2 version.
> But org.apache.groovy:groovy-all:4.0.2 doesn't have classes which we use in our project.

> JavaLexer
> JavaRecognizer
> GroovyLexer
> GroovyRecognizer
> PreOrderTraversal
> SourceCodeTraversal
> Visitor
> SimpleGroovyClassDocAssembler
> In this method we create SimpleGroovyClassDoc. Do you have the same classes in Groovy 4?
