## System requirements

{% include note.html content="PMD and CPD need at least a java7 runtime environment. For analyzing Salesforce.com Apex source code, you’ll need a java8 runtime environment." %}

## New Supported Languages

*   Salesforce.com Apex is now supported by PMD and CPD. See [PR#86](https://github.com/pmd/pmd/pull/86).
*   CPD now supports Perl. See [PR#82](https://github.com/pmd/pmd/pull/82).
*   CPD now supports Swift. See [PR#33](https://github.com/adangel/pmd/pull/33).

## New and Modified Rules

*   New rules in Java:

    *   java-logging-java/InvalidSlf4jMessageFormat: Check for invalid message format in slf4j loggers. See [PR#73](https://github.com/pmd/pmd/pull/73).
    *   java-design/ConstantsInInterface: Avoid constants in interfaces. Interfaces should define types, constants are implementation details better placed in classes or enums. See Effective Java, item 19\. See [PR#93](https://github.com/pmd/pmd/pull/93).
*   Modified rules in Java:

    *   java-comments/CommentRequired: New property <tt>serialVersionUIDCommentRequired</tt> which controls the comment requirements for _serialVersionUID_ fields. By default, no comment is required for this field.
    *   java-design/UseVargs: public static void main method is ignored now and so are methods, that are annotated with Override. See [PR#79](https://github.com/pmd/pmd/pull/79).
*   New rules for Salesforce.com Apex:

    *   apex-complexity: AvoidDeeplyNestedIfStmts, ExcessiveParameterList, ExcessiveClassLength, NcssMethodCount, NcssTypeCount, NcssConstructorCount, StdCyclomaticComplexity, TooManyFields, ExcessivePublicCount
    *   apex-performance: AvoidDmlStatementsInLoops, AvoidSoqlInLoops
    *   apex-style: VariableNamingConventions, MethodNamingConventions, ClassNamingConventions, MethodWithSameNameAsEnclosingClass, AvoidLogicInTrigger, AvoidGlobalModifier
*   Javascript

    *   New Rule: ecmascript-unnecessary/NoElseReturn: The else block in a if-else-construct is unnecessary if the <tt>if</tt> block contains a return. Then the content of the else block can be put outside. See [#1486](https://sourceforge.net/p/pmd/bugs/1486/).

## Improvements and CLI Changes

*   A JSON-renderer for PMD which is compatible with CodeClimate. See [PR#83](https://github.com/pmd/pmd/pull/83).
*   [#1360](https://sourceforge.net/p/pmd/bugs/1360/): [core] [java] Provide backwards compatibility for PMD configuration file
*   CPD: If a complete filename is specified, the language dependent filename filter is not applied. This allows to scan files, that are not using the standard file extension. If a directory is specified, the filename filter is still applied and only those files with the correct file extension of the language are scanned.
*   CPD: If no problems found, an empty report will be output instead of nothing. See also [#1481](https://sourceforge.net/p/pmd/bugs/1481/)
*   CPD: New command line parameter <tt>--ignore-usings</tt>: Ignore using directives in C# when comparing text.
*   PMD: New command line parameter: <tt>-norulesetcompatibility</tt> - this disables the ruleset factory compatibility filter and fails, if e.g. an old rule name is used in the ruleset. See also [#1360](https://sourceforge.net/p/pmd/bugs/1360/). This option is also available for the ant task: <tt><noRuleSetCompatibility>true</noRuleSetCompatibility></tt>.
*   PMD: New command line parameter: <tt>-filelist</tt>- this provides an alternative way to define, which files should be process by PMD. With this option, you can provide the path to a single file containing a comma delimited list of files to analyze. If this is given, then you don’t need to provide <tt>-dir</tt>. See [PR#98](https://github.com/pmd/pmd/pull/98).
