我在grad尔也经历过同样的问题。可惜的是，在maven中实现一个补丁并不是那么容易。下面是我添加到build.gradle中的代码，允许我对com.amazonaws进行适当着色：

shadowJar {
  zip64 true
  mergeServiceFiles()
  relocate('com.amazonaws', 'shaded.com.amazonaws')
  transform(RelocateAmazonawsServiceRequestHandlers.class)
}

import com.github.jengelman.gradle.plugins.shadow.transformers.Transformer
import com.github.jengelman.gradle.plugins.shadow.transformers.TransformerContext
import shadow.org.apache.tools.zip.ZipOutputStream
import shadow.org.apache.tools.zip.ZipEntry

class RelocateAmazonawsServiceRequestHandlers implements Transformer {
  private Map<String, String> transformedResources = new HashMap<>()

  @Override
  boolean canTransformResource(FileTreeElement fileTreeElement) {
    return (fileTreeElement.getName() ==~ /com\/amazonaws\/services\/.*\/request.handlers/)
  }

  @Override
  void transform(TransformerContext transformerContext) {
    String text = transformerContext.is.text
    transformerContext.relocators.each {
      r -> text = r.applyToSourceContent(text)
    }
    transformedResources.put(transformerContext.path, text)
  }

  @Override
  boolean hasTransformedResource() {
    return transformedResources.size() > 0
  }

  @Override
  void modifyOutputStream(ZipOutputStream zipOutputStream) {
    transformedResources.each { key, value ->
      zipOutputStream.putNextEntry(new ZipEntry(key))
      zipOutputStream.write(value.getBytes())
      zipOutputStream.flush()
    }
  }
}

您可以尝试将serviceresourcetransformer添加到配置中：

<transformers>
     <transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer"/>
</transformers>
