java - 将 Katalon Studio 更新至版本 5.9.1 - ClassNotFoundException

Question

将 Katalon Studio 更新到 5.9.1 后，在 Jenkins 中运行测试时，我们的自定义关键字类偶尔会出现 java.lang.ClassNotFoundException: cz.elektLabs.Keywords。

奇怪的是，这种情况并不是每次都会发生，而且我们无法重现它。之前它在 5.7 中有效。

这是我们的自定义关键字类的开头:

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) {
        ...
    }
    ...
}

这是我们得到的错误:

我们可以做些什么来解决这个问题吗？

编辑:我们将 Katalon Studio 更新到版本 5.10.1，但我们仍然时不时地收到 ClassNotFoundException 或 NoClassDefFoundError。
