Netbeans does not install on MacOS Big Sur

Question

I have installed Big Sur on my MacBook Air. Java is installed but Netbeans install says no Java JDK found. Did anybody has the solution for this issue?

Answer 1

I solved it by installing JDK15 and Apache Netbeans 12.2 (Only 12.2).

It works well.

Answer 2

Here's how I resolved it. From the command line, I ran:

/usr/libexec/java_home -V

This will output the Java VMs you have installed:

Matching Java Virtual Machines (4):
    14.0.1 (x86_64) "UNDEFINED" - "OpenJDK 14.0.1" /usr/local/Cellar/openjdk/14.0.1/libexec/openjdk.jdk/Contents/Home
    1.8.271.09 (x86_64) "Oracle Corporation" - "Java" /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
    1.8.0_271 (x86_64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_271.jdk/Contents/Home
    1.8.0_251 (x86_64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_251.jdk/Contents/Home

If you don't see JDK 1.8, then you should go to Oracle.com and install it. Assuming you have 1.8, you should set that as your JAVA_HOME with the following command:

export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.8.0_271.jdk/Contents/Home"

Note that your location may be slightly different from mine, you should use the location for 1.8 that was present in your list of VMs when you ran /usr/libexec/java_home -V, above. I would also recommend you add this to your shell profile so that the current JAVA_HOME is set the next time you reopen your shell. I'm using ZSH as my shell, so the command was:

echo 'export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.8.0_271.jdk/Contents/Home"' >> ~/.zshrc

Now you're almost home. Just make sure you have Homebrew and then run brew cask install netbeans.

That should enable you to install it without issue and will place it in your Applications folder.
