jenv

The jenv resource reference. This resource installs jenv, a Java version manager that allows the system to switch between multiple versions of Java and use one as the global default. For more information on jenv, see here. Normally, jenv will not automatically install java on your behalf unlike nvm or pyenv. However, this resources has additional custom functionality and will attempt to install LTS versions of Java using the openjdk@ formulas if Homebrew is installed.

Parameters:

global: (string) The global version of Java to use.
add: (array[string]) Java install location to add. This accepts a relative or absolute path to a java home directory. Some common locations for Java installations are:
- Homebrew (aarch64): /opt/homebrew/Cellar/[openjdk@21]/21.0.3/libexec/openjdk.jdk/Contents/Home
- Homebrew (Intel): /usr/local/opt/[openjdk@21]/libexec/openjdk.jdk/Contents/Home
- Regular Java installs: /Library/Java/JavaVirtualMachines/[zulu-18.jdk]/Contents/Home
- Note that the bolded sections represent a specific installation of Java. Replace it your version to make it work.
Additionally a integer version number can be provided for LTS versions. This resource will attempt to install the Java version directly using homebrew if it’s available using the openjdk formulas. The versions that are available for automated install are [8, 11, 17, 21, 22].

Dependencies:

There is a dependency on homebrew only if automated Java installations are needed. Otherwise, jenv can operate independently of homebrew.

Example usage:

[
  {
    "type":  "jenv",
    "global": "21",
    "add": [
      "21",
      "8",
      "/Library/Java/JavaVirtualMachines/zulu-18.jdk/Contents/Home"
    ]
  }
]

Setting up Java

Create a codify.json file anywhere.
Open codify.json with your file editor and paste in the follow configs.

[
  { "type": "homebrew" },
  {
    "type":  "jenv",
    "global": "21",
    "add": [
      "21"
    ]
  }
]

Run codify apply in the directory of the file. Open a new terminal and run the command java --version to confirm that Java has been installed
