我们使用以下技术/框架：
- 春季 2_5 -> 春季 5_0_9
- JSF 1_2 -> 2_2 Java
- 6 -> Java 8
- 雄猫 6 -> 雄猫 8_5
以下是我在升级过程中遇到的错误：

INFO: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.

检查您的项目是否包含 .来自 jsf-impl.jar 文件的 TLD 文件。将其与旧罐子的顶级域名进行比较。如果它们都相同，则这样做：从JD-GUI打开新的JAR文件并获取新的.TLD文件并替换为您项目的现有TLD，而不是清理所有内容，然后重试。
