c++ - 未知包装 nar - nar-maven-plugin

Question

我使用 Maven 来管理我的 Java 项目构建，但有时我有用 C 或 C++ 语言编写的项目，我也想使用 Maven，这样管理这些项目会更容易。

看来 nar-maven-plugin 应该可以完成这项工作。我试图创建一个 HelloWorld 项目来测试它。我认为它会非常简单，因为它通常与 Maven 一起使用。

我的 pom.xml

<project
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.sample</groupId>
  <artifactId>helloworld-cplusplus-sample</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>nar</packaging>
  <name>Helloworld</name>
  <build>
    <plugins>
      <plugin>
        <groupId>com.github.maven-nar</groupId>
        <artifactId>nar-maven-plugin</artifactId>
        <version>3.2.3</version>
        <configuration>
            <libraries>
                <library>
                    <type>executable</type>
                </library>
            </libraries>
        </configuration>
      </plugin>
    </plugins>
  </build>
</project>

我有以下错误

我正在使用 Maven 3.3.1。

我使用“mvn dependency:get ...”在我的本地存储库中强制下载了 nar-maven-plugin，但它没有改变任何东西。

当插件添加新的包装类型时，必须添加<extensions>true</extensions>其定义:

<plugin>
    <groupId>com.github.maven-nar</groupId>
    <artifactId>nar-maven-plugin</artifactId>
    <version>3.2.3</version>
    <extensions>true</extensions> <!-- This needs to be present for a new packaging -->
    <configuration>
        <libraries>
            <library>
                <type>executable</type>
            </library>
        </libraries>
    </configuration>
  </plugin>
