Groovy parser does not support multiple assignments

[jevanlingen]

What is the smallest, simplest way to reproduce the problem?

@Test
void multipleAssignments() {
    rewriteRun(
        groovy(
            """
            def (a, b) = ['1', '2']
            """
        )
     );
 }

What did you expect to see?

Working tests

What did you see instead?

Failed to parse file.groovy at cursor position 0. The next 10 characters in the original source are `def (a, b)`

Pointers

There is no implementation yet. In the GroovyParserVisitor you can see this:

if (expression.isMultipleAssignmentDeclaration()) {
    // def (a, b) = [1, 2]
    throw new UnsupportedOperationException("Parsing multiple assignment (e.g.: def (a, b) = [1, 2]) is not implemented");
}
