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 the 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
