大家好。我在测试 split 函数功能的时候，添加了个 case
org.apache.calcite.test.SqlOperatorTest#testSplitFunction
> f.checkScalar("SPLIT('h-e-l-l-o', '-')[0]", "h", "VARCHAR");
>
我发现我使用 gradlew build 整个项目时会出错，但我单独在 IDEA 里面执行这个 case 是成功的。

我在big-query.iq 中加入下面这段
> SELECT SPLIT("h,e,l,l,o", ',')[1] as result;
> +------- +
> | result |
> +------- +
> | e |
> +------- +

报错如下：
