Maven Shade打包含动态加载类的Jar后AWS Lambda找不到Geotools Length函数

问题背景 #

我使用maven-shade-plugin对Jar包进行shade和精简处理后上传至AWS Lambda，运行时抛出类缺失异常，根据现有信息判断大概率是动态类加载机制导致，目前未找到对应解决方案，也不清楚除已尝试操作外还可以如何排查处理。我已了解Jar Shade的基本原理，但未找到该特定问题的相关文档。

构建日志如下：

[INFO] Replacing original artifact with shaded artifact.
[INFO] Replacing /home/ro007848/Workspace/geometry-service/target/geometry-service-1.0.0.jar with /home/ro007848/Workspace/geometry-service/target/geometry-service-1.0.0-shaded.jar

包内容验证结果 #

我解压生成的Jar包后在org/geotools目录下执行grep -r "Length"，结果如下：

................
Binary file ows/wms/CRSEnvelope.class matches
Binary file filter/FilterSAXParser.class matches
Binary file filter/FilterDOMParser.class matches
Binary file filter/LengthFunction.class matches
Binary file filter/function/StaticGeometry.class matches
Binary file filter/function/FilterFunction_strLength.class matches
Binary file filter/function/FilterFunction_strToLowerCase.class matches
Binary file filter/function/FilterFunction_strToUpperCase.class matches
Binary file filter/function/FilterFunction_geomLength.class matches
Binary file filter/ExpressionDOMParser.class matches
Binary file referencing/util/CRSUtilities.class matches
Binary file referencing/crs/DefaultProjectedCRS.class matches
................

Length相关的类已经被打进包中，不清楚异常提示的缺失内容具体指向什么，也不知道如何进一步调试该问题，同时希望了解是否有通用的maven-shade-plugin include配置可以解决这类动态类加载导致的类缺失问题。

已尝试的无效方案 #

有人建议在shade配置中显式引入指定类，配置如下，但执行后无效：

<filter>
    <artifact>org.geotools:gt-main</artifact>
    <includes>
        <include>org/geotools/filter/LengthFunction.class</include>
    </includes>
</filter>

补充信息 #

本地运行集成测试完全正常，所有所需函数都可以正常加载，只有部署到AWS Lambda后运行相同测试才会触发失败。由于涉及动态类加载逻辑，无法通过常规debug手段定位到需要引入的类。

编辑补充：
经mvn help:effective-pom -Dverbose命令验证，使用的GeoTools版本为25.1，不存在版本冲突问题：
