--------------------------------
Resolution: Information Provided
> Groovy 4 doesn't have classes from groovy.antlr

> Key: GROOVY-11130
> URL: https://issues.apache.org/jira/browse/GROOVY-11130
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 4.0.0
> Environment: Gradle 7.1
> Java SDK 11
> Groovy 3.0.9 -> Groovy 4.0.2
> Reporter: Dmitry
> Priority: Major

> 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.
> AntlrASTProcessor
> SourceBuffer
> UnicodeEscapingReader
> Groovifier
> Java2GroovyConverter
> JavaLexer
> JavaRecognizer
> GroovyLexer
> GroovyRecognizer
> PreOrderTraversal
> SourceCodeTraversal
> Visitor
> SimpleGroovyClassDocAssembler
> In this method we create SimpleGroovyClassDoc. Do you have the same classes
> in Groovy 4?
