jmeter 2.9不会打开用jmeter 2.8构建的脚本

我有一个脚本，可以在jmeter的2.8版本中正常运行。我刚刚下载了JMeter2.9，无法打开此脚本

我在日志文件中遇到以下错误，我似乎不明白DummySampler的问题是什么，根据日志，DummySampler似乎是错误的来源。 我查看了2.9版本更改日志页面，没有发现任何相关内容

我是Jmeter和Java新手，非常感谢您的帮助

您应该手动更改JMX，因为存在不同的格式。你可以读到

这是通过安装JavaSE1.7.0.67来修复的，很抱歉，我没有遵守。我在2.8版jmeter中使用的脚本也是.jmx文件。我需要做哪些更改？打开Jmeter 2.9并尝试手动添加测试计划。保存并比较两个jmx文件后，您应该会看到差异。很抱歉，我不明白。我在2.8版jmeter中使用的脚本也是.jmx文件。我需要做哪些更改？打开Jmeter 2.9并尝试手动添加测试计划。保存并比较两个jmx文件后，您应该会看到差异。谢谢您的帮助。我想我把2.8上所有的罐子都抄了一遍。糟糕的是，我在lib下的ext文件夹中遗漏了几个。现在可以了，谢谢你的帮助。我想我把2.8上所有的罐子都抄了一遍。糟糕的是，我在lib下的ext文件夹中遗漏了几个。现在可以了。
