Cannot get it working - error: cannot find symbol

See original GitHub issue

Hello,

I’m really glad I’ve discovered this amazing project, but I’m running into a weird error with manifold and I cannot get it working at all. The project is a multi-module Gradle setup and I’m using manifold version 2022.1.9

TestCsv.csv

a  ,b  ,c
bla,bli,blub

    @Test
    void calculate() {
        TestCsv test = TestCsv.fromSource();

        for (TestCsv.TestCsvItem testCsvItem : test) {
            System.out.println(testCsvItem.getA__());
        }
    }
