----------------------------------------------

             Summary: Groovysh doesn't handle multiline strings with """ or ''' correctly
                 Key: GROOVY-10681
                 URL: https://issues.apache.org/jira/browse/GROOVY-10681
             Project: Groovy
          Issue Type: Bug
          Components: Groovysh
    Affects Versions: 3.0.11
         Environment: Mac M1
JVM: GraalVM CE 22.1.0 (17.0.3)
Groovy 3.0.9 / 3.0.10 / 3.0.11
            Reporter: Marcelo Javier Glezer


I've embedded a GroovySh console inside a server and using it works fine except when i try to parse multiline strings like:
a='''Hello
World'''
in the console it will fail as soon as i hit enter
{code:java}
console:000> a='''Hello
ERROR org.apache.groovy.parser.antlr4.GroovySyntaxError:
Unexpected character: '\'' {code}
and it will point to the third quote on line 1
 
On the server side i get this exception:
{code:java}

I have discussed this over Slack with [~paulk] and he was able to reproduce this error. He commented that slashy strings works (and they do) 
{code:java}
a=/Hello
World/ {code}
and that the issue may be related to this fix: [https://github.com/apache/groovy/commit/c28da4be]
not been updated in GroovySh.
 
You can check the whole conversation over slack (thread) here:
