Its simple:) jodd-lagarto
module depends on jodd-core
module that has the missing class (as well as other utils Lagarto is using). Check the download page to see all modules and dependencies. For your version there might be also a dependency on slf4j
logger (this has been removed recently).
You may also consider using some dependency management tool, like gradle or maven. Than all dependencies will be automatically downloaded.
If possible, try using the latest version of Jodd :) At this moment it's 3.4.10; 3.5 is almost out. The new versions contain some important Lagarto-related improvements, fixes and performance boosting :) Enjoy!
