Uncaught Exception java.lang.NoClassDefFoundError: Could not initialize class org.apache.jmeter.gui.util.FileDialoger. See log file for details.

我安装了apache-jmeter-5.1.1和java 1.8.0_221（8），并且正在通过getting started guide来在GUI中构建Web测试计划。但是，当我单击“保存”以保存测试计划时，会收到上述错误。

任何想法如何解决？

Answer 1

尝试以下操作：

打开JMeter->选项->外观->选择任何其他主题除了德古拉。
重新启动JMeter创建测试计划并尝试保存。
保存应该可以。

Answer 2

如果您在选择“打开项目”或“保存项目”选项后看到以下错误，则为

java.lang.ExceptionInInitializerError: null

在Windows 10上使用jmeter 5.0或更高版本的解决方案：

JMeter->选项->外观->选择Darcula以外的其他主题。
重新启动JMeter
打开/保存选项应该起作用
