Description

Contributor guide

Research direction

The issue reports a NoClassDefFoundError for com/alibaba/excel/support/cglib/core/NamingPolicy in easyexcel 3.1.2. This is a missing dependency, likely cglib. The fix involves adding the cglib dependency to the project's build configuration (e.g., Maven pom.xml or Gradle build.gradle) or verifying version compatibility. The stack trace points to ExcelBuilderImpl.addContent, so the dependency is required at runtime. Check the easyexcel documentation for required dependencies.
