Selenium 代码在 localhost 上运行良好，但无法在 Jenkins 上捕获 StaleElementReferenceException

Question

代码：

try {
  driver.findElement(By.xpath("//div/table[@class='v-table-table']/descendant::tr/td[1])").click();
} catch(StaleElementReferenceException e) {
   // some code
}

此代码在本地运行良好，异常由 catch 块处理，我的代码继续执行，但是当我在 Jenkins 上运行相同的代码时，catch 块无法捕获异常。

Found Element By : By.xpath: //div/table[@class='v-table-table']/descendant::tr/td[1]

日志：

Exception occured: org.openqa.selenium.StaleElementReferenceException: The element reference of <td class="v-table-cell-content"> is stale; either the element is no longer attached to the DOM, it is not in the current frame context, or the document has been refreshed

您的 java.version: '1.8.0_151' 太旧了。

将 JDK 更新到当前级别 JDK 8u311 并执行您的测试。

错误错误堆栈跟踪还提到：

[GC (Allocation Failure)  56810K->10231K(139776K), 0.0097259 secs]

GC (Allocation Failure)是GC循环启动的效果。

分配失败意味着没有更多空间可以分配对象。较旧的 JVM 不会为次要 GC 周期打印 GC 原因。 分配失败几乎是次要 GC 的唯一可能原因。启动次要 GC 的另一个原因可能是 CMS 备注阶段（如果启用了 +XX:+ScavengeBeforeRemark）。
