JDK vendors

cjdk allows you to choose among JDKs and JREs released from different sources. Names such as adoptium, zulu-jre, or graalvm-java17 are used to select a particular series of JDKs. These names are referred to as “vendors”, even though they do not map 1:1 to companies.

If no vendor is specified, adoptium is used unless the environment variable CJDK_VENDOR is set to an alternative default.

About available vendors

The available set of vendors is determined by the JDK index and is not built into cjdk itself.

Common vendors include adopt, adoptium, temurin, liberica, zulu, and their JRE counterparts adopt-jre, adoptium-jre, temurin-jre, liberica-jre, zulu-jre.

AdoptOpenJDK was succeeded by Eclipse Temurin by Adoptium in 2021. To specifically get AdoptOpenJDK releases, use adopt; to specifically get Temurin releases, use temurin; adoptium will get a Temurin release if available, falling back to AdoptOpenJDK for older versions. (Again, this behavior is defined by the index, not cjdk itself.)

For GraalVM, graalvm-java11, graalvm-java16, and graalvm-java17 are available at the time of writing (these each have versions that are numbered independently of the regular JDK version).
