Autofix of UnnecessaryGString leaves invalid code in data provider of Spock tests

[sdoeringNew]

Hi,

I'm using npm-groovy-lint with my Spock tests that have a data provider for several test cases.

def "Test: #testCaseTitle"() {
    when:
    def result = testedMethod(json)

    then:
    result != null

    where:
    testCaseTitle     | json                                                      || errorMessage
    'missing image'   | """{ "view": "available", "options": ["empty"] }"""       || """JSON is missing image"""
    'missing options' | """{ "view": "available", "image": "${placeholder}" }"""  || """JSON is missing options"""
    'missing view'    | """{ "image": "${placeholder}", "options": ["empty"] }""" || """JSON is missing view"""
    'all missing'     | """{ }"""                                                 || """JSON is missing image, JSON is missing options, JSON is missing view"""
}

After auto-fixing the code using npm-groovy-lint the source code got uncompilable because of wrongly replaced GString quotes.

def "Test: #testCaseTitle"() {
    when:
    def result = testedMethod(json)

    then:
    result != null

    where:
    testCaseTitle     | json                                                      || errorMessage
    'missing image'   | '''{ "view": "available", "options": ["empty"] }"""       || ""'JSON is missing image'""
    'missing options' | '''{ "view": "available", "image": "${placeholder}" }"""  || ""'JSON is missing options'""
    'missing view'    | """{ "image": "${placeholder}", "options": ["empty"] }""" || ""'JSON is missing view'""
    'all missing'     | ""'{ }'""                                                 || ""'JSON is missing image, JSON is missing options, JSON is missing view'""
}

npm-groovy-lint does not detect the end of the GStrings correctly and therefore replaces the the quotes at the wrong place leaving the source code uncompilable.

This:

"""{ "view": "available", "options": ["empty"] }"""

Becomes that:

'''{ "view": "available", "options": ["empty"] }"""

This:

"""JSON is missing image"""

Becomes that:

""'JSON is missing image'""

That behaviour is not good.

Kind regards
