我正在JMeter中创建一个自定义Java采样器。它工作得很好。然而,当我希望它以JSON返回结果时,JMeter没有找到。jackson数据绑定库的jar,它是创建JSON所必需的。
我把它放在JMeter主目录中的/lib/ext文件夹中。我还复制到/lib,但没有任何效果。(我知道/lib/ext不应该用于依赖JAR,但根据我的经验,JMeter在/lib中找不到我的实用JAR。)
我尝试将路径添加到变量search\u paths,user。jmeter中的类路径和plugin\u dependency\u路径。属性。我尝试了绝对路径、相对路径、斜杠、反斜杠,但都没用。
我尝试将JMETER\u HOME变量设置为安装地址。它起作用了,但没用。
我尝试在两种环境中运行。第一个是在Eclipse中(我将JMeter复制到一个工作区文件夹,然后导入项目),使用JMeter 4.0。我在日志中发现以下错误:

我还从运行了JMeter 3.3。bat文件,将JAR添加到同一位置。我在控制台上发现此错误:

我没有尝试调试类加载器,但当我在这里发布完后,这可能是下一步。
我有此版本的文件,与我的POM中的文件相同:
https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind/2.9.4
