Recently, I deployed a Minecraft server on a Linux system and used my self-developed plugin called blbiLogin. During this process, I encountered some unexpected issues. Specifically, I discovered that the SQLite database files could not be created or read properly, which caused some server functionalities to malfunction.

After careful investigation, I finally identified the root cause of the problem. It turned out that when specifying the database file path, I had inadvertently capitalized a letter that should have been lowercase. This seemingly trivial error didn't catch my attention on the Windows system because Windows is not case-sensitive when it comes to file names and paths. However, when I migrated the server to a Linux system, the issue became apparent.

Linux systems are extremely case-sensitive when it comes to file names and paths, treating uppercase and lowercase letters as entirely different characters. This led to the system being unable to locate the correct file path, subsequently causing the SQLite files to fail in creation and reading. This experience made me deeply aware of the importance of paying attention to details in cross-platform development, especially when dealing with file paths.

This incident also reminded me that when engaging in cross-platform development, it's crucial to conduct thorough testing on different operating systems to ensure the software functions properly in various environments. Additionally, developing the habit of using relative paths or normalized paths can, to some extent, help avoid similar issues.
