To add additional buckets of tools, there's a nifty command to do so. Read on. #### Add the `java` Bucket To get access to all install binaries for java, you'll need to add the `java` bucket. Run the following command: ```powershell scoop bucket add java // List all available Adoptium-based JREs/JDKs scoop search temurin ``` #### Install Adoptium Temurin JDK 17 Install Adoptium's Temurin JDK 17 LTS in Powershell ```powershell scoop install temurin17-jdk # Refresh powershell refreshenv # OR just close the shell and open a new instance # Check if JRE is available java -version # Check if JDK is available javac -version ```
