How to set JAVA_HOME with install-jdk.sh

• Source install-jdk.sh into current shell to install latest OpenJDK and let it update JAVA_HOME and PATH environment variables:

  • source ./install-jdk.sh Caveat: if an error happens during script execution the calling shell will terminate

• Provide target directory path to use as JAVA_HOME:

  • JAVA_HOME=~/jdk && ./install-jdk.sh --target $JAVA_HOME && PATH=$JAVA_HOME/bin:$PATH

• Run install-jdk.sh in a sub-shell to install latest OpenJDK and emit the installation path to stdout:

  • JAVA_HOME=$(./install-jdk.sh --silent --emit-java-home)
  • JAVA_HOME=$(./install-jdk.sh --emit-java-home | tail --lines 1)
