首先下载com.abobe,ac.pmd.eclipse_...jar 和 flex-pmd-all-in-one...zip俩文件

前面一个装在xx\adobe flash builder xx\eclipse\plugins下，后面随便放哪，但路径中不能有空格，解压之。

重启fb,再配置下,窗口->首选项->flexpmd

FlexPMD command line installation xx\flex-pmd-all-in-one..\flex-pmd-command-line-1.2.jar
FlexPMD custom ruleset：xx\flex-pmd-all-in-one..\rules\pmd_rule.xml
FlexCPD command line installation：xx\flex-pmd-all-in-one..\flex-pmd-cpd-command-line-1.2.jar
