安装环境
进入下载的vm bin目录下，打开cmd，执行如下命令
安装native-image
gu install native-image
D:\jdks\graalvm-ce-java11-22.3.1\bin>gu install native-image
Downloading: Component catalog from www.graalvm.org
Processing Component: Native Image
Downloading: Component native-image: Native Image from github.com
Installing new component: Native Image (org.graalvm.native-image, version 22.3.1)
查看安装情况
gu list
如下，表示没有安装，native-image
ComponentId Version Component name Stability Origin
---------------------------------------------------------------------------------------------------------------------------------
graalvm 22.3.1 GraalVM Core Supported
安装成功，会多一个native-image
D:\jdks\graalvm-ce-java11-22.3.1\bin>gu list
ComponentId Version Component name Stability Origin
---------------------------------------------------------------------------------------------------------------------------------
graalvm 22.3.1 GraalVM Core Supported
native-image 22.3.1 Native Image Early adopter github.com
编译成本地exe
安装vs,
打开
x64 Native Tools Command Prompt for VS 2022
设置环境变量
setx /M PATH "D:\jdks\graalvm-ce-java11-22.3.1\bin;%PATH%"
# Java环境
setx /M JAVA_HOME "D:\jdks\graalvm-ce-java11-22.3.1"
环境成功
C:\Users\wwj>native-image
Please specify options for native-image building or use --help for more info.
开始编译
在上上面的窗口，进入到class文件，
注意需要使用类的全路径，不要带class
native-image xxx
如果出现某些文件找不到，就使用管理员模式
