我的 SCR 插件无法正常工作。我已经尽可能多地进行了搜索，但只找到了与我需要使用的结构不相似的示例。下面是 POM 的片段。这些几乎是 CQ 项目原型生成的默认值。所有依赖项都在那里，所以可能不是这样。这是构建的输出：
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
