I am attempting to set up ./mirror, and have gotten to the step of running

./mirror server

That gives the error

./mirror: line 9: java: command not found

I have replicated this issue on two boxes. If I am making a mistake, please let me know. If this is an issue, please fix and let me know what I can do to help. Thank you!

I just installed Java with

sudo apt-get install openjdk-7-jre

and got this error

Hi, thanks for reporting this! I had not documented it (I'll add it to the readme), but mirror requires Java 8. Can you install openjdk-8-jre and see if that works?

goosehub commented 7 years ago

Unfortunately I've already found another tool for this task. Also, I'm not familiar with Java. Thanks for quickly getting back to me though!

Np, the communication is still appreciated to help the next person. Good luck!
