Original GitHub issue: https://github.com/FiloSottile/mkcert/issues/201

I keep getting:

Warning: "keytool" is not available, so the CA can't be automatically installed in Java's trust store! ⚠️

When it plainly is available, I can just type "keytool" and it works. JAVA_HOME is set just fine. I'm really at a loss because everything else can access it just fine.

Weird! Can you give us the output of which keytool and echo $PATH? Are you running mkcert with sudo, maybe?

Observed same issue due to wrong path in JAVA_HOME, once correct path is present, issue wasn't observed. Thanks for the tip 'which keytoolandecho $PATH', helped me to resolve it.

Hi @ajith-sdet what is the JAVA_HOME correct path? echo $PATH return these:
/Users/xxxxxx/bin:/Users/xxxxxx/.dotfiles/modules/dotly/bin:/Users/xxxxxx/.dotfiles/bin:/Library/Java/JavaVirtualMachines/amazon-corretto-15.jdk/Contents/Home/bin:/Users/monchyrcg/.gem/bin:/Users//.go/bin:/Users//.cargo/bin:/usr/local/opt/ruby/bin:/usr/local/opt/python/libexec/bin:/opt/homebrew/bin:/usr/local/bin:/usr/local/sbin:/bin:/usr/bin:/usr/sbin:/sbin
