無法在Eclipse中導入PMD規則集

Question

我想在我的Sonar配置文件的IDE（Eclipse）中使用相同的規則集。

我從聲納永久鏈接的PMD的XML規則集，並希望將其導入到我的PMD Eclipse插件，但是當我嘗試這樣做，「確定」按鈕desactivated ...

有人可以幫我嗎？

Answer 1

問題可能在於Sonar正在導出v4.x格式的規則集，並且您的Eclipse插件期望它們是v5.x格式。

嘗試更改您的規則：

<rule ref="rulesets/basic.xml/UnusedNullCheckInEquals"> 
    <priority>3</priority> 
</rule> 

到

<rule ref="rulesets/java/basic.xml/UnusedNullCheckInEquals"> 
    <priority>3</priority> 
</rule> 

請注意：裁判屬性。一個簡單的查找和替換都可以爲你工作。

Answer 2

爲什麼不使用Sonar Eclipse？您不需要擔心規則集的同步。

Answer 3

Ivan Nikolov的回答是正確的。你的問題是規則集格式的不同版本。在我的情況下，我試圖將從PMD插件版本3.2.6導出的規則集導入插件版本4.0.0。這裏是我的發現：

• Ivan Nikolov提到的路徑變化是所有規則都需要的。要小心，因爲並不是所有規則都屬於java（我也看到了XML的規則，...）。我對PMD並不那麼深入，所以我不知道在哪個版本中引入了其他技術的規則。
• 爲了與舊的自定義規則集文件進行比較，導出PMD插件4.0.0的默認規則集非常有用。這樣你就可以解決下一個問題。
• 在你的行爲被拋出的異常是不可視化的。該異常可以在工作區日誌文件（/.metadata/.log）中看到。這可以給你一個線索，還有什麼需要改變。使用上一點來了解如何解決問題。在我的情況下，它被改變路徑一個規則從 到

這些變化，我能夠導入手動遷移自定義的規則集文件到PMD插件4.0.0之後。

希望這會有所幫助。

BTW：我覺得版本4.0.0 PMD的插件非常錯誤，所以我降級到3.2.6

Answer 4

伊萬·尼科洛夫的建議幫助我，但我不得不改變也從一個規則：

<rule ref="rulesets/java/controversial.xml/UnusedModifier"> 
    <priority>5</priority> 
</rule> 

到

<rule ref="rulesets/java/unusedcode.xml/UnusedModifier"> 
    <priority>5</priority> 
</rule> 

下面是它爲我工作與PMD-插件4.0.2聲納我PMD的配置文件。：

Answer 5

除了別人怎麼說，你也必須找到這樣的：

net.sourceforge.pmd.rules.XPathRule 

並以此替換：

net.sourceforge.pmd.lang.rule.XPathRule 

Answer 6

我不得不把語言添加到我的XPath規則也是如此，例如：

<rule name="DontUseDate" language="java" class="net.sourceforge.pmd.lang.rule.XPathRule" ...></rule>
