Maven Dependency Plugin 离线不下载一些插件

Question

我正在尝试将 pom 文件的所有传递依赖项和插件下载到本地文件夹中，然后将其用于运行 sonarqube 离线。我是 Maven 的新手，所以我可能在这里做错了什么，但我认为 Maven maven-dependency-plugin:3.1.1:go-offline 没有下载运行 sonarqube 所需的所有插件，这导致一个错误。

这是我试过的。

将所有依赖项下载到新文件夹

mvn -D"maven.repo.local"="c:\test\test" org.apache.maven.plugins:maven-dependency-plugin:3.1.1:go-offline

运行声纳

mvn -o -D"maven.repo.local"="c:\test\test" sonar:sonar

然而，这给了我以下错误

因为它抱怨各种插件不可用，我发现 maven-dependency-plugin 有问题，没有下载运行 sonarqube 所需的所有必要插件？有什么解决办法吗？

Answer 1

sonar-maven-plugin 应声明为插件而不是依赖项。

<build>
  <pluginManagement>
    <plugins>
      <plugin>
        <groupId>org.sonarsource.scanner.maven</groupId>
        <artifactId>sonar-maven-plugin</artifactId>
        <version>3.6.0.1398</version>
      </plugin>
    </plugins>
  </pluginManagement>
</build>
