GraalVM初体验

安装

# 下载GraalVM
https://www.graalvm.org/downloads/#

# 解压

# 配置PATH,这里需要将 GraalVM\bin 目录配置到PATH
setx /M PATH "C:\Progra~1\Java\<graalvm>\bin;%PATH%"
# 同时，JAVA_HOME 也需要配置成 GraalVM\bin ，这样才能使用 GraalVM 提供的JDK，否则编译不通过。
setx /M JAVA_HOME "C:\Progra~1\Java\<graalvm>"

# 安装 Visual Studio ，在官网下载最新的Visual Studio 并参考 GraalVM 的说明安装必要的组件。

手动 maven 编译命令，编译成功后在 target 目录下就会生成可执行文件。

mvn clean -Pnative native:compile -DskipTests
