Could not find tools.jar. Please check that /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home contains a valid JDK installation

The problem is that with the update the built-in java took precedence and it doesn’t have the SDK because it’s just the runtime.

You just need to change your java home and add the java binary to your .zshrc to find your java home execute:

/usr/libexec/java_home -V | grep jdk

the output should be similar to the following:

Matching Java Virtual Machines (1):
1.8.0_272 (x86_64) "AdoptOpenJDK" - "AdoptOpenJDK 8" /Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home
/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home

you should take the path from the one that says SDK in my case

/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home

after that, you just add the following to the end of your .zshrc that should be in your home.

You can edit it with (if you decide to use vim you can exit writing :wq! and pressing enter)

vim .zshrc

add the following:

export JAVA_HOME=the/path/you/copied/before
export PATH=$JAVA_HOME/bin:$PATH

where the/path/you/copied/before in my case would be

/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home

save the file and close all your terminals and open them again.

The error should be solved.
