我正在处理一个AEM项目，并在构建我的maven项目时遇到以下错误。

不确定它从哪里引用"output_xml.properties"文件。
org.apache.felix：maven-scr-plugin plugin，使用此插件，必须在项目描述符中将其声明为元素：
<project>
...
<build>
...
<plugins>
...
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-scr-plugin</artifactId>
<version>1.20.0</version>
<executions>
<execution>

<goals>
<goal>scr</goal>
</goals>
</execution>
</executions>
</plugin>
...
</plugins>
...
</build>
...
</project>
如果要使用 maven-scr 插件处理标准注释，请添加此依赖项：
<project>
...
<dependencies>
...
<dependency>
<groupId>org.apache.felix</groupId>
<artifactId>org.apache.felix.scr.ds-annotations</artifactId>
<version>1.2.4</version>
<scope>provided</scope>
</dependency>
...
</dependencies>

延迟了几个月的回答，但我能够通过导入并使用 SlingAllMethodsServlet 扩展我的类来解决我的错误
。 import org.apache.sling.api.servlets.SlingAllMethodsServlet; ... 公共类 扩展 SlingAllMethodsServlet ....{ ... }
