pmd代碼檢測規則修改

以下是一份pmd的rules文件

[html] view plain copy

1. <?xml

   version="1.0"

   ?>

2. <ruleset

   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="Android Application Rules"

3. xmlns="http://pmd.sf.net/ruleset/1.0.0"
4. xsi:noNamespaceSchemaLocation="http://pmd.sf.net/ruleset_xml_schema.xsd"
5. xsi:schemaLocation="http://pmd.sf.net/ruleset/1.0.0 http://pmd.sf.net/ruleset_xml_schema.xsd"

這次主要講的是怎麼移除已有的規則（由於if嵌套需要合併的規則感覺不合理所以今天研究了一下怎麼將這一條規則移除）；

首先我們看一張官網上的規則分類圖：

由以上這張圖可以知道，pmd規則是由幾大類構成，每個大類下面又有細則，所以我想要將我不要的規則移除的話，首先我要找到歸屬的大類，假如我報錯的地方點進來是對應著ForLoopShouldBeWhileLoop這個，那麼我們只需要將

<rule ref="rulesets/java/basic.xml" />

這段改為

<rule ref="rulesets/java/basic.xml">

<exclude name="ForLoopShouldBeWhileLoop" />

</rule>

是不是超級簡單哈～～～～主要是exclude關鍵字在起作用哦～～
