New and noteworthy

CPD now supports XML as well

Thanks to Fernando Cosso CPD can now find duplicates in XML files as well. This is useful to find duplicated sections in XML files.

New Rules

• The new Java Rule {% rule "java/bestpractices/LiteralsFirstInComparisons" %} (java-bestpractices) find String literals, that are used in comparisons and are not positioned first. Using the String literal as the receiver of e.g. equals helps to avoid NullPointerExceptions.

  This rule is replacing the two old rules {% rule "java/bestpractices/PositionLiteralsFirstInComparisons" %} and {% rule "java/bestpractices/PositionLiteralsFirstInCaseInsensitiveComparisons" %} and extends the check for the methods compareTo, compareToIgnoreCase and contentEquals in addition to equals and equalsIgnoreCase.

  Note: This rule also replaces the two mentioned rules in Java's quickstart ruleset.
