Agenda CodeNarc GMetrics 

CodeNarc http://codenarc.sourceforge.net/ CodeNarc analyzes Groovy code for defects, bad practices, inconsistencies, style issues and more. A flexible framework for rules, rulesets and custom rules means it's easy to configure CodeNarc to fit into your project. Build tool, framework support, and report generation are all enterprise ready. 

CodeNarc Can be runed from - command line - as ant task - as maven task - as gradle task - as grails plugin 

CodeNarc at gradle apply plugin: 'code-quality' codeNarcConfigFileName = 'config/codenarc/rules.groovy' 

CodeNarc ruleset ruleset { description 'Rules Sample Groovy Gradle Project' ruleset('rulesets/basic.xml') ruleset('rulesets/braces.xml') ruleset('rulesets/exceptions.xml') ruleset('rulesets/imports.xml') ruleset('rulesets/logging.xml') ruleset('rulesets/naming.xml') { 'ClassName' { enabled = false } } ruleset('rulesets/unnecessary.xml') { 'UnnecessaryReturnKeyword' { enabled = false } } ruleset('rulesets/unused.xml') }

Gmetrics http://gmetrics.sourceforge.net/ The GMetrics project provides calculation and reporting of size and complexity metrics for Groovy source code. GMetrics scans Groovy source code, applying a set of metrics, and generates an HTML report of the results. 

Gmetrics • Cyclomatic Complexity. • ABC Size/Complexity. Also see the C2 Wiki page. • Lines per method • Lines per class 

Gmetrics at Grails • grails install-plugin gmetrics • grails gmetrics
