Choice of JDKs

Java development kits (JDK) and runtime environments (JRE) are available through the Scoop Java bucket.

To add the bucket, run:

scoop bucket add java

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

  • AdoptOpenJDK 12 with Oracle HotSpot JVM

    adopt12-hotspot.json can be installed with:

    scoop install adopt12-hotspot

  • AdoptOpenJDK 12 JRE with Oracle HotSpot JVM (runtime environment)

    adopt12-hotspot-jre.json can be installed with:

    scoop install adopt12-hotspot-jre
Eclipse OpenJ9 JVM

  • AdoptOpenJDK 12 with Eclipse OpenJ9 JVM

    adopt12-openj9.json can be installed with:

    scoop install adopt12-openj9

  • AdoptOpenJDK 12 JRE with Eclipse OpenJ9 JVM (runtime environment)

    adopt12-openj9-jre.json can be installed with:

    scoop install adopt12-openj9-jre

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.

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.

Example of switching between versions
