Other error conditions:

2. In many cases, after copying the jar package to the specified directory, you need to add the full path of the jar package to the CLASSPATH, otherwise problems such as ClassNotFoundException may occur.
3. The version of dependencies is incompatible, and the version used at compile time is different from the version used at runtime.
4. So please check whether your CLASSPATH contains the full path of the jar package.
