sdk install java 23.1.1.r21-nik
# 设置为默认jdk
sdk default java 23.1.1.r21-nik

设置环境便令#

# export JAVA_HOME=$(/usr/libexec/java_home) # 注意sdkman的java home不同
export JAVA_HOME=$HOME/.sdkman/candidates/java/23.1.1.r21-nik/
export GRAALVM_HOME=$JAVA_HOME
export NIK_HOME=$JAVA_HOME
export PATH=$JAVA_HOME:$PATH
# 打开新的终端看看能否找到gu命令
