I have a Macbook Air 2014 and I’m trying to update to the new Mac OS, which is Catalina. When trying to download I get this message, “Downloading installer information to the target volume failed.” I already tried to repair disk permissions and restarting the computer, yet I get the same message.

Unlike other version managers such as NVM, jEnv itself doesn’t install JDKs. You have to do it yourself. Luckily, Homebrew Cask made this task really easy. But before doing that, let’s check if we already have JDK 7 installed by Homebrew Cask:
install Java 7:

If you run into permission issue, add sudo at the beginning of the above command.
As of today, Java 8 is the latest stable. Run the following command to install Java 8:
brew cask install java
These two JDKs will be installed at the following directories. Your JDKs’ minor and patch versions might be different.
Enter jEnv
Now it is time to install jEnv:

The above command will create a .java-version file at project root. Its content is the version I just picked for this project:
