Geb - IncompatibleClassChangeError [英] Geb - IncompatibleClassChangeError

问题描述

I'm just starting out with Geb and am encountering this error when inputting sample code from the Book of Geb:

我刚刚开始使用Geb，并在从Geb Book输入示例代码时遇到此错误。 import geb.Browser


Browser.drive {
gohttp://google.com/ncr

//确保我们确实转到页面
assert title ==Google

//在搜索栏输入wikipedia
$（input，name：q）。value wikipedia）

//等待结果页发生变化
//（google无需新请求即可动态更新页面）
waitFor {title.endsWith（ Google Search）}

//是维基百科的第一个链接？
def firstLink = $（li.g，0）.find（al）
assert firstLink.text（）==Wikipedia

//点击链接
firstLink.click（）

//等待Google的javascript重定向到Wikipedia
waitFor {title ==Wikipedia}
}

import geb.Browser Browser.drive { go "http://google.com/ncr" // make sure we actually got to the page assert title == "Google" // enter wikipedia into the search field $("input", name: "q").value("wikipedia") // wait for the change to results page to happen // (google updates the page dynamically without a new request) waitFor { title.endsWith("Google Search") } // is the first link to wikipedia? def firstLink = $("li.g", 0).find("a.l") assert firstLink.text() == "Wikipedia" // click the link firstLink.click() // wait for Google's javascript to redirect to Wikipedia waitFor { title == "Wikipedia" } }

我遇到这个异常：

I am encountering this exception:

Caught: java.lang.IncompatibleClassChangeError: the number of constructors during runtime and compile time for java.lang.Exception do not match. Expected 4 but got 5
    at geb.error.GebException.<init>(GebException.groovy:20)
    at geb.waiting.WaitTimeoutException.<init>(WaitTimeoutException.groovy:30)
    at geb.waiting.Wait.waitFor(Wait.groovy:108)
        .......

有什么想法？谢谢！

推荐答案

您是否正在使用Java 7？使用<<编译的异常的Groovy代码Java 7与Java 7不兼容。

Are you using Java 7 by any chance? Groovy code that uses exceptions that was compiled with < Java 7 is not compatible with Java 7.
