我必须创建自己的插件来解析 xml 并做其他事情。我创建了自己的捆绑插件，其中包含我的解析器类 pom.xml，如下所示：
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</dependencies>
之后，我想创建将解析 xml 的类，并且我想使用 org.apache.xerces 包。
我还创建了其他包含 org.apache.xerces jar 的包，并且我已经安装了它，它在http://myhost.com:4502/system/console/bundles中处于活动状态。
当我想在核心插件（上面的 pom.xml）中的 Java 类中声明 DOMParser 变量时：
package pl.mycompany.myproject.page.components;
import java.util.Date;
import org.apache.sling.api.resource.Resource;
import org.apache.xerces.parsers.DOMParser;
enter code here
public class EqAndSpecParser {
private Resource resource;
public EqAndSpecParser(Resource resource) {
this.resource = resource;
}
public void checkIfNeedToUpdate(Date lastModifiedDate, String lastGenerationDate, String xmlCode) {
try {
DOMParser parser = new DOMParser();
parser.parse(xmlCode);
} catch (Exception e) {
e.printStackTrace();
}
}
public Resource getResource() {
return resource;
}
public void setResource(Resource resource) {
this.resource = resource;
}
}
然后我在 /crx-quickstart/logs/ 中得到错误：

DOMParser 只是我想使用的示例类。在我的项目中，我需要使用来自其他提供商的外部 jar，即 POC。主要问题是：如何在 CQ5 中使用外部 jar？如何将它们安装到所有自定义插件都将使用这些 jar 的 CQ 中？
当我将 xerces 依赖项更改为
<dependency>
<groupId>xerces</groupId>
<artifactId>xercesImpl</artifactId>
<version>2.9.0</version>
<scope>compile</scope>
</dependency>
我<Embed-Dependency>xercesImpl;scope=compile</Embed-Dependency>
现在添加了如下错误：
