NonGUIDriver中的錯誤-java.lang.NullPointerException

Question

我目前正在將jmeter與Maven集成。
使用
雅加達-傑米特2.4
依賴-Jmeter2.3和所有受支持的jar
我正在通過GUI創建測試計划，並用jmx保存了它。
我正在使用maven-jmeter-plugin 1.0並在maven-jmeter-plugin中添加兩個依賴關系肥皂和common-logging。
通過在我運行mvn verify時執行此操作，它給出了一個錯誤：

在網上，我得到了三種解決方案：

1. Java版本
2. 添加肥皂和普通登錄依賴
3. 在.jmx文件中，TestPlan標簽應為根elemnrt，並通過右鍵單擊TestPlan保存測試
   

但是，這些都不對我有用。

Answer 1

使用最新版本（撰寫本文時為1.4）。

現在可以在中央Maven倉庫中使用它，有關更多信息，請訪問項目網站-> http://jmeter.lazerycode.com

Answer 2

使用1.10.1版時遇到了相同的問題，並意識到我正在使用自定義插件。 刪除它們並使用開箱即用的jmeter測試計划解決了該問題。

Answer 3

請注意，如果您使用的是JMeter 2.4中提供的JMeter功能（即JMeter 2.3中不存在），則maven-jmeter-plugin不會是最新的，也無法正確處理-因為它基於JMeter 2.3。

我還將在您的jmeter.log中查找更多信息。
