PMD Release Notes

??-????-2020 - 6.27.0-SNAPSHOT

The PMD team is pleased to announce PMD 6.27.0-SNAPSHOT.

This is a minor release.

New and noteworthy

New Rules

• The new Java rule AvoidReassigningCatchVariables (java-bestpractices) finds cases where the variable of the caught exception is reassigned. This practice is surprising and prevents further evolution of the code like multi-catch.

Deprecated Rules

• The Java rule DataflowAnomalyAnalysis (java-errorprone) is deprecated in favour of UnusedAssignment (java-bestpractices), which was introduced in PMD 6.26.0.

Fixed Issues

  • #2668: [java] UnusedAssignment false positives
• java-errorprone
  • #2431: [java] InvalidLogMessageFormatRule throws IndexOutOfBoundsException when only logging exception message
  • #2439: [java] AvoidCatchingThrowable can not detect the case: catch (java.lang.Throwable t)
  • #2647: [java] Deprecate rule DataFlowAnomalyAnalysis
• java-performance
  • #2441: [java] RedundantFieldInitializer can not detect a special case for char initialize: char foo = '\0';

API Changes

• XML rule definition in rulesets: In PMD 7, the language attribute will be required on all rule elements that declare a new rule. Some base rule classes set the language implicitly in their constructor, and so this is not required in all cases for the rule to work. But this behavior will be discontinued in PMD 7, so missing language attributes are now reported as a forward compatibility warning.

Deprecated API

• Rule#getParserOptions
• Parser#getParserOptions
• net.sourceforge.pmd.lang.AbstractParser
• RuleContext#removeAttribute
• RuleContext#getAttribute
• RuleContext#setAttribute
• ApexParserOptions
• ASTThrowStatement#getFirstClassOrInterfaceTypeImage
• EcmascriptParserOptions
• EcmascriptXPathRule
• XmlParserOptions
• XmlXPathRule

• Properties of AbstractXmlRule

• net.sourceforge.pmd.Report.ReadableDuration

• Many methods of net.sourceforge.pmd.Report. They are replaced by accessors that produce a List. For example, iterator() (and implementing Iterable) and isEmpty() are both replaced by getViolations().

• The dataflow codebase is deprecated for removal in PMD 7. This includes all code in the following packages, and their subpackages:
  • net.sourceforge.pmd.lang.plsql.dfa
  • net.sourceforge.pmd.lang.java.dfa
  • net.sourceforge.pmd.lang.dfa
  • and the class PLSQLDataFlowHandler
