如何找到我应该排除库的依赖项？

Question

我将 Maven 从 3.0.5 更新到 3.5.3 版本。我使用 ma​​ven-site-plugin-3.7。

更新后我尝试执行命令“mvn site site:deploy”。我有以下错误：

[ERROR] : org.apache.commons.logging.LogConfigurationException: 
org.apache.commons.logging.LogConfigurationException: Invalid class loader 
hierarchy.  You have more than one version of 
'org.apache.commons.logging.Log' visible, which is not allowed. (Caused by 
org.apache.commons.logging.LogConfigurationException: Invalid class loader 
hierarchy.  You have more than one version of 
'org.apache.commons.logging.Log' visible, which is not allowed.) (Caused by     
org.apache.commons.logging.LogConfigurationException:

org.apache.commons.logging.LogConfigurationException: Invalid class loader 
hierarchy.  You have more than one version of 
'org.apache.commons.logging.Log' visible, which is not allowed.))

当我执行 dependency:tree 或 dependency:list 我有空的依赖列表。当我执行 dependency:resolve-pugins 我有以下内容：

由于我从 commons-logging 库中理解了 org.apache.commons.logging.Log，因此需要将该库从某些依赖项中排除。但我在依赖项列表中没有看到 commons-logging。

问题是我找不到应该排除 commons-logging 的位置。

如何找到应该排除 commons-logging 依赖项的位置？还是有其他问题？

Answer 1

尝试向您的 pom 添加特定版本依赖项，例如：

    <dependency>
        <groupId>commons-logging</groupId>
        <artifactId>commons-logging</artifactId>
        <version>1.2</version>
    </dependency>

我看到有时可以修复它，有时会为您提供有关传递依赖的更多信息
