【janino】janino自定义函数报错A method named "xx" is not declared in any enclosing class nor through a static

1.背景

想测试janino的自定义函数，但是不知道怎么做，随便写一下报错

 @Test
    public void janinoPerformanceTest2_1() throws Exception {

        String rule = "containsIgnoreCase(requestUrl,\"/ls5/forum.php\")";

        IExpressionEvaluator evaluator = CompilerFactoryFactory.getDefaultCompilerFactory().newExpressionEvaluator();
        evaluator.setExpressionType(boolean.class);
        evaluator.setParameters(
                new String[]{"requestUrl"},
                new Class[]{String.class}
        );
        evaluator.cook(rule);

        Object[] arguments = {"/securityEyeLogType"};
        Object res = evaluator.evaluate(arguments);
        System.out.println(res);

    }

报错如下

org.codehaus.commons.compiler.CompileException: Line 1, Column 20: A method named "containsIgnoreCase" is not declared in any enclosing class nor any supertype, nor through a static import
