That sets the right environment variables for a JVM to be used: $ cs java -jvm 11 -env Passing -env to the java command makes it print a bash script $ cs java -jvm 13 -version # picks adopt:13.0.2 OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.6+10, mixed mode) OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.6+10) This feature can be combined with version intervals above: $ cs java -jvm 11 -version # picks adopt:11.0.6 If one only specifies a version, with no JVM type upfront, AdoptOpenJDK OpenJDK 64-Bit Server VM (build 14+35-1460, mixed mode, sharing) OpenJDK Runtime Environment (build 14+35-1460) For exampleġ9.3 gets substituted by 19.3+, which will match all 19.3.x versions,Īnd the latest one will be selected: $ cs java-home -jvm graalvm:19.3 # picks cs java -jvm openjdk:14 -version # picks openjdk:1.14.0 If the version doesn't exactly matchĪn available one, it is assumed it corresponds to an interval. The full names from the index can be cumbersome to If needed, that index could be complemented or replaced byĪn index of our own at some point. To list the JVM that can be installed from it, run $ cs java -available This index is regularly updated, and lists a large variety of JVMs The AdoptOpenJDK 13.0.2 JVM is automatically downloaded and extractedĬs java -available lists the JVMs available in the index: $ cs java -available | grep adoptĬs java -installed lists the ones currently installed on your system: $ cs java -installedĬurrently, the java and java-home commands rely on OpenJDK 64-Bit Server VM AdoptOpenJDK (build 13.0.2+8, mixed mode, sharing) OpenJDK Runtime Environment AdoptOpenJDK (build 13.0.2+8) One can run the java binary from AdoptOpenJDK 13.0.2 via $ cs java -jvm adopt:13.0-2 -version This, the default JVM is the latest AdoptOpenJDK 8 from theīoth java and java-home commands accept a JVM name via -jvm. If no JVM is installed on your system, the default one is automaticallyĮxtracted in the JVM cache, and used.

Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home Likewise, the java-home command prints its base directory, which can look like $ cs java-home Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode) Java(TM) SE Runtime Environment (build 1.8.0_121-b13) Simply calls it, just as if you called it yourself: $ java -version If a JVM is already installed on your system, the java command The java and java-home commands fetch and install JVMs.
