FastExcel 1.3 → Apache Fesod Migration Skill

The official Fesod migration doc recommends a three-phase gradual approach; this skill implements all three phases in one pass, but each phase is clearly labelled so the developer can stop after Phase 1 or Phase 2 if needed.

Phase 1 — Dependency swap (REQUIRED, zero code changes)

This phase alone is sufficient to make the project compile and run on Fesod with deprecation warnings. It is always safe to stop here first and run tests.

1a. Maven — single-module project

In pom.xml, find the FastExcel dependency block:

<dependency>
    <groupId>cn.idev.excel</groupId>
    <artifactId>fastexcel</artifactId>
    <version>...</version>
</dependency>

Replace it with:

<dependency>
    <groupId>org.apache.fesod</groupId>
    <artifactId>fesod-sheet</artifactId>
    <version>2.0.1-incubating</version>
</dependency>

Also remove the FastExcel version property if it exists, e.g.:

<fastexcel.version>1.3.0</fastexcel.version>

1b. Gradle

In build.gradle (or build.gradle.kts), replace:

// Groovy DSL
implementation 'cn.idev.excel:fastexcel:1.3.0'
