Jmeter failed to start with the Prometheus JMX agent when run not from $JMETER_HOME/bin
问题
尝试配置Prometheus JMX代理以用于Jmeter，但遇到以下问题 - 当我在**$JMETER_HOME/bin**文件夹之外启动Jmeter时 - 它会因错误而失败：
java.lang.Throwable: 无法访问 null/lib
at org.apache.jmeter.NewDriver.<clinit>(NewDriver.java:105)
java.lang.Throwable: 无法访问 null/lib/ext
at org.apache.jmeter.NewDriver.<clinit>(NewDriver.java:105)
java.lang.Throwable: 无法访问 null/lib/junit
at org.apache.jmeter.NewDriver.<clinit>(NewDriver.java:105)
java.lang.ClassNotFoundException: org.apache.jmeter.JMeter
at java.net.URLClassLoader.findClass(URLClassLoader.java:382)
at java.lang.ClassLoader.loadClass(ClassLoader.java:418)
at java.lang.ClassLoader.loadClass(ClassLoader.java:351)
at org.apache.jmeter.NewDriver.main(NewDriver.java:250)
JMeter的主目录被检测为：null
启动命令：
java -Dcom.sun.management.jmxremote.port=12021 -Dcom.sun.management.jmxremote.rmi.port=12021 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Dgroovy.use.classvalue=true -javaagent:/apps/injector/apache-jmeter/bin/jmx_prometheus_javaagent-0.13.0.jar=8778:/apps/injector/apache-jmeter/bin/prometheus_config.yaml -jar /apps/injector/apache-jmeter/bin/ApacheJMeter.jar -n -t /apps/injector/apache-jmeter/extras/Test.jmx
相同的命令在我从**$JMETER_HOME/bin文件夹运行时正常工作。这似乎不是Jmeter本身的问题，因为我可以从任何地方运行相同的命令，并且如果我删除-javaagent**选项，它不会导致错误。
有人可以帮助我正确配置Prometheus JMX代理以使其与Jmeter正常工作吗？
英文:
Trying configure Prometheus JMX agent for Jmeter but faced following issue - when I start Jmeter outside of $JMETER_HOME/bin folder - it fails with an error:

JMeter home directory was detected as: null
Launch command:
java -Dcom.sun.management.jmxremote.port=12021 -Dcom.sun.management.jmxremote.rmi.port=12021 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Dgroovy.use.classvalue=true -javaagent:/apps/injector/apache-jmeter/bin/jmx_prometheus_javaagent-0.13.0.jar=8778:/apps/injector/apache-jmeter/bin/prometheus_config.yaml -jar /apps/injector/apache-jmeter/bin/ApacheJMeter.jar -n -t /apps/injector/apache-jmeter/extras/Test.jmx
Same command works fine in case I run it from $JMETER_HOME/bin folder.
It's not seems to be a Jmeter issue itself, as I can run same command from any place, and it will not cause an error in case I remove -javaagent option.
Can somebody help me configure Prometheus JMX agent for properly work with Jmeter.

将以下内容添加到JMeter的Java选项中：
-Djmeter.home=$JMETER_HOME
