Java Editions available

OpenJDK

OpenJDK is the preferred JDK (because of its Open Source license).

The Scoop Java bucket contains five different OpenJDK builds.

Oracle OpenJDK

Oracle's OpenJDK version (openjdk.json) can be installed with:

scoop install openjdk

AdoptOpenJDK

AdoptOpenJDK has versions with HotSpot and Eclipse OpenJ9 JVMs.

Oracle HotSpot JVM

OpenJDK 8 with Oracle HotSpot JVM

adopt8-upstream.json is the preferred Java 8 JDK. Oracle does not distribute Oracle 8 JDK:s anymore, see FAQ here. Oracle 8 JRE is available through the oraclejre8.json manifest.

AdoptOpenJDK with Oracle HotSpot JVM

adoptopenjdk-hotspot.json can be installed with:

scoop install adoptopenjdk-hotspot
AdoptOpenJDK JRE with Oracle HotSpot JVM (runtime environment)

adoptopenjdk-hotspot-jre.json can be installed with:

scoop install adoptopenjdk-hotspot-jre

Eclipse OpenJ9 JVM

AdoptOpenJDK with Eclipse OpenJ9 JVM

adoptopenjdk-openj9.json can be installed with:

scoop install adoptopenjdk-openj9
AdoptOpenJDK JRE with Eclipse OpenJ9 JVM (runtime environment)

adoptopenjdk-openj9-jre.json can be installed with:

scoop install adoptopenjdk-openj9-jre

Zulu

ojdkbuild

ojdkbuild manifests requires lessmsi to be installed and configured by running scoop config MSIEXTRACT_USE_LESSMSI true.

Amazon Corretto

Oracle JDK

Oracle’s Java is also available in the oraclejdk manifest.

Switching Javas

There are two solutions available today for switching java:

  1. scoop reset <java>[@<version>]
  2. Using find-java from extras

scoop reset works very well for the current session, and will also update the user's path. Please note https://github.com/lukesampson/scoop/issues/3822 - currently this isn't working for all available packages.

Globally installed javas takes precedence over user-installed javas, so running sudo scoop install -g oraclejdk-lts will install a java that is always default for new sessions.
