nar-maven-plugin＆gt; = 3.3.0失败，并且“未指定msvc.version”

Question

我想在一台带有Maven和Cygwin的gcc的Windows机器上构建一个helloworld C程序。使用nar-maven-plugin版本3.2.3构建成功，但如果使用像3.4.0这样的更高版本，则构建总是失败

  

[错误]无法在项目helloworld上执行目标com.github.maven-nar：nar-maven-plugin：3.4.0：nar-validate（default-nar-validate）：未指定msvc.version且没有VSCOMNTOOLS环境

为什么？我不想使用Microsoft编译器。

我的项目结构：

    src/main/c/helloworld.c
    pom.xml

我的pom.xml：
