Checkstyle is not working while building the project in eclipse

Question

I am facing checkstyles issue while building the project. Please guide me based on my below error message as soon as possible.

Errors occurred during the build:

Errors running builder 'Checkstyle Builder' on project 'CMS'.

ReturnNullInsteadOfBoolean is not part of the core Checkstyle distribution. Instead, it is part of SevNTU - which is typically not installed into Eclipse by default.

In Eclipse, under the "Help" menu, select "Install New Software...". Search for "EclipseCS SevNTU plugin feature", check its box, then install.

This may also appear as "Extension for eclipse-cs plugin with additional Checks".

Please comment back if this still doesn't work for you.

RedundantThrows was removed with version 6.2 of Checkstyle, and will need to be removed from your project's Checkstyle configuration. See also: stackoverflow.com/questions/27919444/…
