Thank you for this recent tutorial on how to manage Java versions with Homebrew. Most other guides I tried to follow are written for outdated
brewfunctionality.Quick warning: This does NOT seem to work if you have Java installed in some way through
conda. I hadopenjdkinstalled in mycondabaseenv (it was required by another program installed with conda) and I could not get this solution to work until I uninstalledopenjdkfrom my activecondaenv or switched to an env withoutopenjdkinstalled. I'm sure it was a problem with myPATH, but since I couldn't figure it out after a while, I just made a new conda env with the tools that automatically install their ownopenjdkand uninstalledopenjdkfrom my activecondabase env. Everything seems to work great now, thanks a ton!Edit: I seem to be running into a problem where the command
export JAVA_HOME=[...]in my~/.zshrcdoesn't seem to actually setJAVA_HOME. E.g. as soon as I start a new shell window and typeecho $JAVA_HOME, nothing appears and upon inspection of variables listed byenv,JAVA_HOMEdoes not appear. Interestingly, if I typejava -version, it does show myadoptopenjdk14as the current version even though the variableJAVA_HOMEdoesn't exist. Any idea why? It does set itself when I run one of the aliases, but that requires manually running the alias.Edit 2: I found the problem: It was because I still had some code in my
.zshrcfrom trying a previous solution.Hey Marc, you should check out SDKMAN!, you can easily switch between (but also install and uninstall) different Java (and Scala, and Gradle, and Kotlin, Groovy, sbt, Spring Boot, ...) versions using SDKMAN! It's seriously amazing, and really easy to use.
Hi Andrew, thanks for the tip! I'll it try out!
