PMD 5.7.0

Modified Rules:
The rule “FieldDeclarationsShouldBeAtStartOfClass” of the java-design ruleset has a new property ignoreInterfaceDeclarations. Setting this property to true ignores interface declarations, that precede fields.
Renderers:
Added the ‘empty’ renderer which will write nothing. Does not affect other behaviors, for example the command line PMD exit status will still indicate whether violations were found.
Fixed Issues:
General
[core] Use maven wrapper and upgrade to maven 3.5.0.
[core] Improve build time on travis.
[java] Parser Error for empty statements.
java-coupling
[java] Law of Demeter violations for the Builder pattern.
Java-design

Java-strings
[java] [doc] Add suggestion to use StringUtils#isBlank for InefficientEmptyStringCheck.
Jsp-basic
[jsp] Wrong issue “JSP file should use UTF-8 encoding”.
API Changes:
The method net.sourceforge.pmd.util.StringUtil#htmlEncode(String) is deprecated. org.apache.commons.lang3.StringEscapeUtils#escapeHtml4(String) should be used instead.
