Maven可解析其他依赖却无法解析Xerces依赖问题咨询

我的pom.xml配置如下：

执行mvn clean install时出现以下错误：

Failed to execute goal on project xml-parsing: Could not resolve dependencies for project org.example:xml-parsing:jar:1.0-SNAPSHOT: The following artifacts could not be resolved: org.apache.xerces:org.apache.xerces:jar:2.12.2, org.apache.xerces:xml-apis:jar:2.11.0-20110622: Could not find artifact org.apache.xerces:org.apache.xerces:jar:2.12.2 in central (https://repo.maven.apache.org/maven2)  

已尝试的操作：

• 添加另一组groupId为org.apache.xerces的依赖，仍无法解析；
• 添加apache-commons依赖，可正常解析。

需要了解问题原因及解决方法。

问题原因 #

你配置的org.apache.xerces:org.apache.xerces:2.12.2这个构件不在Maven中央仓库中。中央仓库里Xerces的标准artifactId并非org.apache.xerces，而是xercesImpl，对应的依赖结构也有区别。

解决方法 #

将原有的Xerces依赖替换为中央仓库中存在的正确配置：

<dependency>
    <groupId>xerces</groupId>
    <artifactId>xercesImpl</artifactId>
    <version>2.12.2</version>
</dependency>

或者如果偏好使用org.apache.xerces作为groupId，可使用以下配置：

<dependency>
    <groupId>org.apache.xerces</groupId>
    <artifactId>xercesImpl</artifactId>
    <version>2.12.2</version>
</dependency>

替换完成后重新执行mvn clean install，Maven即可正常解析该依赖。
