[groovy-user] [ANN] Announcing CodeNarc 0.9

[chris...@wachovia.com]

CodeNarc is a static analysis tool for Groovy source code.
 
Version 0.9 includes:
 
Bug Fixes

• Fix bug #2985592: “MissingPropertyException: No such property: W3C_XML_SCHEMA_NS_URI”.
• XML RuleSet: Allow wildcards (*) in <include> and <exclude>.
• NestedBlockDepthRule: Ignore first level of closure for Closure Fields (since they are really equivalent to methods).

New Size/Complexity Rules

• AbcComplexityRule - Check ABC size/complexity score against threshold for method and class average (size)
• CyclomaticComplexityRule - Check Cyclomatic Complexity against threshold for method and class average (size)

New Concurrency Rules (from Hamlet D’Arcy)

• NestedSynchronizationRule (concurrency - Hamlet D’Arcy)
• RunFinalizersOnExitRule (concurrency - Hamlet D’Arcy)
• SynchronizedMethodRule (concurrency - Hamlet D’Arcy)  
• SynchronizedOnThisRule (concurrency - Hamlet D’Arcy)
• ThreadLocalNotStaticFinalRule (concurrency - Hamlet D’Arcy)
• ThreadYieldRule: (concurrency - Hamlet D’Arcy)
• VolatileLongOrDoubleFieldRule: (concurrency - Hamlet D’Arcy)

New Basic Rules

• CloneableWithoutCloneRule (basic - Hamlet D'Arcy & René Gröschke)
• ConstantIfExpressionRule (basic)
• ConstantTernaryExpressionRule (basic)
• UnnecessaryTernaryExpressionRule (basic)

New Features and Infrastructure

• Deprecate GrailsSessionReferenceRule. Default enabled to false.
• StatelessClassRule: Add setAddToIgnoreFieldNames() method (adds to ignoreFieldNames).
• Potential BREAKAGE: Add new <rule>.description.html property for each rule. If you have overridden the “<rule>.description” message for a predefined rule in a “codenarc-messages.properties” file, you will have to change those message keys to “<rule>.description.html”.
• Do not include disabled rules in list of rules at bottom of HTML/XML report.
• UnusedVariableRule: Fix limitation: Does not recognize variable references on the same line as the variable declaration.
• CodeNarcRunner: Add System.out println of summary counts.
• MethodSizeRule: Apply to constructors as well.

** Moving this over to the codenarc-user list. **

Perhaps this is an inconsistency between Java, Groovy or Xerces? Which versions of each of those are you using?

There is a new (insufficiently documented) dependency in CodeNarc on Groovy 1.6 or later (and Java 1.5 or later) and GMetrics if you use the new ABC or Cyclomatic Complexity rules.
