-unzip it somewhere
-cd into the pmd\etc\ directory
C:\tmp\tmp_pmd>cd pmd\etc
C:\tmp\tmp_pmd\pmd\etc>
-run PMD on a Java source file
C:\tmp\tmp_pmd\pmd\etc>run c:\data\pmd\pmd\test-data\UnusedLocal1.java html rulesets/unusedcode.xml

HOW TO RUN PMD FROM THE COMMAND LINE (UNIX)
-download the binary release
-unzip it
[build@ul020-dmz tmp_pmd]$ unzip -q pmd-bin-1.04.zip
-cd into the pmd/etc/ directory
[build@ul020-dmz tmp_pmd]$ cd pmd/etc/
-run PMD on a Java source file
[build@ul020-dmz etc]$ run Foo.java html rulesets/unusedcode.xml

Avoid unused private fields such as '_tasks'
[build@ul020-dmz etc]$
-if you send in a directory as the first parameter, PMD will run recursively on all files and subdirectories
-note that if you're using JDK 1.3, you'll need to use java -cp, not java -jar. Like this:
java -cp lib\pmd-1.04.jar;lib\xercesImpl-2.0.2.jar;lib\xmlParserAPIs-2.0.2.jar;lib\jaxen-core-1.0-fcs.jar;lib\saxpath-1.0-fcs.jar net.sourceforge.pmd.PMD c:\j2sdk1.4.1_01\src\java\lang xml rulesets/imports.xml
