将Katalon Studio更新为5.9.1版-ClassNotFoundException

Question

在将Katalon Studio更新到5.9.1之后，我们偶尔会得到java。lang.ClassNotFoundException:cz。电子实验室。在Jenkins中运行测试时，在我们的自定义关键字类上设置关键字。

奇怪的是，它并不是每次都发生，我们也无法复制它。它以前在5.7版本中有效。

下面是我们自定义关键字类的开始：

package cz.elektLabs
import static com.kms.katalon.core.testobject.ObjectRepository.findTestObject

import org.jsoup.Jsoup
import org.jsoup.nodes.Document
import org.jsoup.nodes.Element
import org.jsoup.select.Elements
import org.openqa.selenium.By

import com.kms.katalon.core.annotation.Keyword
import com.kms.katalon.core.model.FailureHandling
import com.kms.katalon.core.util.KeywordUtil
import com.kms.katalon.core.webui.driver.DriverFactory
import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI

import groovy.json.JsonSlurper
import groovy.time.TimeCategory
import internal.GlobalVariable

class Keywords {
    @Keyword
    def boolean checkIfValidImage(String url) {
        ...
    }
    ...
}

下面是我们得到的错误：

我们能做些什么来解决这个问题吗？

编辑：我们将Katalon Studio更新到5.10.1版本，我们仍然不时收到ClassNotFoundExctive或NoClassDefFoundError。

请确保您已经在机器上安装了Open JDK 1.8。
