cs java

The java and java-home commands fetch and install JVMs. The java command runs them too. More information: https://get-coursier.io/docs/cli-java.

• Display Java version by using coursier:

cs java -version

• Call a specific Java version with custom properties using coursier:

cs java --jvm {{jvm_name}}:{{jvm_version}} -Xmx32m -X{{another_jvm_opt}} -jar {{path/to/jar_name.jar}}

• List all the available JVM in the coursier default index:

cs java --available

• List all the installed JVM in the system with his own location:

cs java --installed

• Set a specific JVM as one-off default for the shell instance:

cs java --jvm {{jvm_name}}:{{jvm_version}} --env

• Revert the changes for the default JVM settings:

eval "$(cs java --disable)"

• Set a specific JVM as default for the whole system:

cs java --jvm {{jvm_name}}:{{jvm_version}} --setup
