下载最新的graalvm sdk

https://github.com/gluonhq/graal/releases

== 使用wsl2 ubuntu 子系统

== 在用户根目录 .bashrc

文末添加, 具体文件位置相应调整。

 ````
export JAVA_HOME=/usr/lib/jvm/java-17-openjdk-amd64
export GRAALVM_HOME=/mnt/c/Users/Administrator/app/graalvm-svm-java17-linux-gluon-22.1.0.1-Final
export ANDROID_SDK=/mnt/c/Users/Administrator/app/android_sdk
export ADB_HOME=/mnt/c/Users/Administrator/app/android_sdk/platform-tools
export PATH=$PATH:$JAVA_HOME/bin:$GRAALVM_HOME:$ANDROID_SDK:$ADB_HOME
````

== 生效文件

source .bashrc

== 切换jdk

sudo update-alternatives --config java

选择版本数字

== 在package阶段，如果是第一次会下载gradle，国内下载容易超时，可开vpn，下载完成后，需要关闭vpn，后续开启vpn会出现错误。一般来说下载完成后，关闭vpn重新执行一次也可。
