Unable to download nextflow on WSL (error: line 322: java: command not found)

[bhoen1]

Hi all,

I am trying to download nextflow on wsl, but I am unable to. The error is related to java (see below).
I tried downloading nextflow with 3 methods:

• wget -qO- https://get.nextflow.io | bash
• curl -s https://get.nextflow.io | bash
• Installing nextflow by downloading on github.

All of them gave a Java related error. I re-downloaded java8.0 but this did not help.

I also have Bash version >3.2

Does someone have an idea how to solve this? Its my first time coding with linux, so I do not have any professional experience.

Thank you in advance!
Babette

Hi @bhoen1 , hopefully you figured out your problem by now but I'll answer just in case.

You should make sure you have java 11 or newer installed. You can install it with sudo apt-get install default-jre or with sdkman:

curl -s "https://get.sdkman.io" | bash
source "${HOME}/.sdkman/bin/sdkman-init.sh"
sdk install java 11.0.12-open 
java -version

Installing Java on Windows doesn't count -- it needs to be installed inside your WSL environment.
