Currently, I am working in a new project and it was difficult for me to understand since there is no comment. I wonder if it is possible to force team members(including me) to add more comments. I would like to automate this ject in jenkins later if possible.
Best How To :
You can run static code checks and their corresponding eclipse plug-ins to enforce comments being made in code.
For e.g. in CheckStyle javadoc can be enforced http://checkstyle.sourceforge.net/config_javadoc.html
Also checkstyle can be easily integrated with Jenkins.
You can also use eclipse java compiler settings for javadoc check.
Go to preferences->java->compiler->javadoc to enforce errors and warnings. Compiler errors and warnings can be easily reported through continuous build
