Fedora系统下无法启动Apache Hop GUI的问题及解决记录

问题现象 #

从官方下载两个版本的Apache Hop压缩包，解压后在终端执行./hop-gui.sh（含sudo尝试），始终无法启动，报错提示找不到图片文件，且压缩包内无UI文件夹。

尝试过的方法 #

• 使用sudo执行./hop-gui.sh
• 更换Java版本（从Java 11切换到Java 17）
• 重启电脑
• 下载多个版本的Apache Hop压缩包
• 检查日志（无日志生成）

最终解决原因 #

问题已解决，原因是Java版本配置错误。电脑深处有一个文件配置了错误的Java路径，找到并修正路径、使用正确Java版本后，一切正常。
