Bukkit Plugin Loading Error: Could not find main class 'com.example.blockcount.main'

The error message indicates that the plugin 'BlockCount-1.0-SNAPSHOT.jar' could not be loaded because the main class 'com.example.blockcount.main' could not be found. This could be due to a missing or incorrect 'plugin.yml' file or an issue with the classpath. The 'plugin.yml' file should specify the main class as 'com.example.blockcount.main'. Double-check that the main class is spelled correctly and that the 'plugin.yml' file is located in the correct directory. If the issue persists, try rebuilding the plugin from scratch or contacting the plugin developer for assistance.
