當我在旅途代理執行printenv命令去哪裏工作從環境變量？
[email protected]:/tmp$ printenv
HOSTNAME=05f749b73185
SHELL=/bin/bash
USER=go
LS_COLORS=
MAVEN_VERSION=3.3.9

但是，當我從工作中執行printenv命令我。如果你看一下JAVA_HOME環境變量得到這樣的結果

當您登錄機器時，直接撥打電話和撥打電話會有所不同。 這可以通過在流水線中設置環境變量來解決，但我怎樣才能配置我的去服務器和去代理，所以我不必這樣做？如果我想將另一個JDK用作默認值，該怎麼辦？
JAVA_HOME環境變量從哪裏來？
