如何解决maven提供的范围问题

Question

我正在构建一个自定义声纳插件，这是一个maven项目。

声纳要求提到它需要sonar-plugin-api依赖作为范围provided。我觉得没问题，因为它会在声纳容器里运行，里面会有这个罐子。

在我的用例中，我想添加httpclient的附加依赖项。如果我将其添加到默认范围下，它将拒绝生成，并抛出以下错误：

[ERROR] This dependency must be declared with scope <provided>: commons-logging:commons-logging:jar
[INFO] ------------------------------------------------------------------------
[INFO] BUILD FAILURE
[INFO] ------------------------------------------------------------------------
[INFO] Total time: 1.364 s
[INFO] Finished at: 2019-03-05T13:52:22+05:30
[INFO] ------------------------------------------------------------------------
[ERROR] Failed to execute goal org.sonarsource.sonar-packaging-maven-plugin:sonar-packaging-maven-plugin:1.18.0.372:check (default-check) on project myPlugin: Unsupported dependencies

如果我将httpclient的范围更改为provided，它将构建，但不会在声纳中工作，因为它的env中没有这个jar。

httpclient中的所有依赖项，包括commons-logging，都被提到为scope - compile。

这就是我现在的pom样子：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

                </configuration>
            </plugin>

        </plugins>
    </build>
</project>

有什么建议，怎么解决？

谢谢

Answer 1

SonarQube插件包含一个检查，它不允许共享日志记录和LOG4J，因为SonarQube只支持SLF4J。

因此，您可以做的是切换到SLF4J，并将commons-logging从httpclient依赖项中排除出来：

    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpclient</artifactId>
        <version>4.3.6</version>
        <exclusions>
            <exclusion>
                <groupId>commons-logging</groupId>
                <artifactId>commons-logging</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>jcl-over-slf4j</artifactId>
        <version>1.7.26</version>
    </dependency>

Answer 2

在<dependencyManagement>部分中添加一个条目来管理commons-logging到provided，即

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>commons-logging</groupId>
      <artifactId>commons-logging</artifactId>
      <version>...</version>
      <scope>provided</scope>
    </dependency>
  </dependencies>
</dependencyManagement>

对于版本:现在使用您在dependency:list中找到的那个。
