Geb给org.openqa.selenium.InvalidSelectorException：

Question

我已将geb核心更新为编译“org.gebish：geb-core：0.10.0”从那时起我的错误

org.openqa.selenium.InvalidSelectorException: 
Locator Strategy 'css selector' is not supported for this session (WARNING: The server did not provide any stacktrace information)

代码

static content = {
        welcomeMessage {$("welcome_message")} // here occurs error org.openqa.selenium.InvalidSelectorException:  
    }

“$（”welcome_message“）”是我找不到的元素，但它显示在屏幕上。我遵循geb语法它看起来一样。

我尝试使用以下语法，但仍然无效

1. welcomeMessage {$（“。welcome_message”）}
2. welcomeMessage {$（“welcome_message”）}
3. welcomeMessage {$（“＃welcome_message”）}
4. welcomeMessage {$（“ - ＃welcome_message”）}
