New and noteworthy
Enhanced Matlab support
Thanks to the contributions from Maikel Steneker CPD for Matlab can
now parse Matlab programs which use the question mark operator to specify access to
class members:
classdef Class1
properties (SetAccess = ?Class2)
CPD also understands now double quoted strings, which are supported since version R2017a of Matlab:
str = "This is a string"
Enhanced C++ support
CPD now supports digit separators in C++ (language module “cpp”). This is a C++14 feature.
Example: auto integer_literal = 1'000'000;
The single quotes can be used to add some structure to large numbers.
CPD also parses raw string literals now correctly (see #1784).
New Rules
The new Apex rule FieldNamingConventions (apex-codestyle) checks the naming
conventions for field declarations. By default this rule uses the standard Apex naming convention (Camel case),
but it can be configured through properties.
The new Apex rule FormalParameterNamingConventions (apex-codestyle) checks the
naming conventions for formal parameters of methods. By default this rule uses the standard Apex naming
convention (Camel case), but it can be configured through properties.
The new Apex rule LocalVariableNamingConventions (apex-codestyle) checks the
naming conventions for local variable declarations. By default this rule uses the standard Apex naming
convention (Camel case), but it can be configured through properties.
The new Apex rule PropertyNamingConventions (apex-codestyle) checks the naming
conventions for property declarations. By default this rule uses the standard Apex naming convention (Camel case),
but it can be configured through properties.
The new Java rule UseShortArrayInitializer (java-codestyle) searches for
array initialization expressions, which can be written shorter.
Modified Rules
The Apex rule ClassNamingConventions (apex-codestyle) can now be configured
using various properties for the specific kind of type declarations (e.g. class, interface, enum).
As before, this rule uses by default the standard Apex naming convention (Pascal case).
The Apex rule MethodNamingConventions (apex-codestyle) can now be configured
using various properties to differenciate e.g. static methods and test methods.
As before, this rule uses by default the standard Apex naming convention (Camel case).
The Java rule FieldNamingConventions (java-codestyle) now by default ignores
the field serialPersistentFields. Since this is a field which needs to have this special name, no
field naming conventions can be applied here. It is excluded the same way like serialVersionUID via the
property exclusions.
The Java rule CommentRequired (java-documentation) has a new property
serialPersistentFieldsCommentRequired with the default value “Ignored”. This means that from now
on comments for the field serialPersistentFields are not required anymore. You can change the property
to restore the old behavior.
The Java rule ProperLogger (java-errorprone) has two new properties
to configure the logger class (e.g. “org.slf4j.Logger”) and the logger name of the special case,
when the logger is not static. The name of the static logger variable was already configurable.
The new property “loggerClass” allows to use this rule for different logging frameworks.
This rule covers all the cases of the now deprecated rule LoggerIsNotStaticFinal.
The Java rule CommentDefaultAccessModifier (java-codestyle) now reports also
missing comments for top-level classes and annotations, that are package-private.
Deprecated Rules
The Apex rule VariableNamingConventions (apex-codestyle) has been deprecated and
will be removed with PMD 7.0.0. The rule is replaced by the more general rules
FieldNamingConventions,
FormalParameterNamingConventions,
LocalVariableNamingConventions, and
PropertyNamingConventions.
The Java rule LoggerIsNotStaticFinal (java-errorprone) has been deprecated
and will be removed with PMD 7.0.0. The rule is replaced by ProperLogger.
Fixed Issues
apex
#1321: [apex] Should VariableNamingConventions require properties to start with a lowercase letter?
#1783: [apex] comments on constructor not recognized when the Class has inner class
cpp
#1784: [cpp] Improve support for raw string literals
dart
#1809: [dart] [cpd] Parse error with escape sequences
java
#1842: [java] Annotated module declarations cause parse error
java-bestpractices
#1738: [java] MethodReturnsInternalArray does not work in inner classes
java-codestyle
#1495: [java] Rule to detect overly verbose array initializiation
#1684: [java] Properly whitelist serialPersistentFields
#1804: [java] NPE in UnnecessaryLocalBeforeReturnRule
python
#1810: [python] [cpd] Parse error when using Python 2 backticks
matlab

#1793: [java] CommentDefaultAccessModifier not working for classes
API Changes
Deprecated APIs
For removal
The DumpFacades in all languages, that could be used to transform a AST into a textual representation,
will be removed with PMD 7. The rule designer is a better way to inspect nodes.
net.sourceforge.pmd.lang.apex.ast.DumpFacade
net.sourceforge.pmd.lang.java.ast.DumpFacade
net.sourceforge.pmd.lang.ecmascript.ast.DumpFacade
net.sourceforge.pmd.lang.jsp.ast.DumpFacade
net.sourceforge.pmd.lang.plsql.ast.DumpFacade
net.sourceforge.pmd.lang.vf.ast.DumpFacade
net.sourceforge.pmd.lang.vm.ast.AbstractVmNode#dump
net.sourceforge.pmd.lang.xml.ast.DumpFacade
The method LanguageVersionHandler#getDumpFacade will be
removed as well. It is deprecated, along with all its implementations in the subclasses of LanguageVersionHandler.
