Eclipse IDE limits the characters that are displayed in its console. But if you are running a task that displays a lot of output then sometimes its not visible.

To see unlimited output

Go to windows > Preferences > Run/Debug > Console and un-check Limit console output

To increase the console buffer size in eclipse

Go to windows > Preferences > Run/Debug > Console and you can provideany number of characters between 1000 to 1000000.

Simple, isn't it :)
