I’ll introduce how to install and manage multiple versions of Java using the asdf plugin asdf-java.
Background: Java Version Management with asdf
I needed to install Java on M1 macOS and had plans to continue development while switching between multiple Java versions, so I decided to use asdf-java.
Prerequisites: Installing asdf
First, complete the asdf installation [M1 macOS edition].
Assumption: Using Java corretto
As a prerequisite, I’ll install the latest versions of corretto-17 and corretto-18 respectively.
- corretto/corretto-17: Amazon Corretto 17 is a no-cost, multi-platform, production-ready distribution of OpenJDK 17
- corretto/corretto-18: Amazon Corretto 18 is a no-cost, multi-platform, production-ready distribution of OpenJDK 18
