無法在Eclipse中導入PMD Ruleset

Question

我想在我的IDE（Eclipse）中使用與Sonar配置文件相同的Ruleset。

我從Sonar Permalinks獲得了PMD XML規則集，並希望將其導入我的PMD Eclipse插件，但是當我嘗試這樣做時，“OK”按鈕被取消激活...

有人能幫我嗎 ？

Answer 1

問題可能是Sonar正在導出v4.x格式的規則集，而Eclipse插件需要它們采用v5.x格式。

嘗試更改以下規則：

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

至

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

請注意ref屬性。 一個簡單的查找和替換將為您做得很好。

Answer 2

Ivan Nikolov的建議幫助了我，但我不得不改變一條規則：

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

至

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

這是我的聲納的PMD配置文件，它適用於PMD-plugin 4.0.2：

Answer 3

我不得不將語言添加到我的XPath規則中，例如：

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

Answer 4

Ivan Nikolov的回答是正確的。 您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。 以下是我的發現：

• 所有規則都需要Ivan Nikolov提到的路徑變化。 要小心，因為並非所有規則都屬於java（我也看到了XML的規則，......）。 我不是那么深入PMD，所以我不知道在哪個版本中引入了其他技術的規則。
• 導出PMD插件4.0.0的默認規則集以與舊的自定義規則集文件進行比較非常有用。 這樣您就可以解決下一點可以發現的問題。
• 在您的行為期間拋出了未可視化的異常。 最后可以在工作區日志文件（/.metadata/.log）中看到此異常。 這可以為您提供其他需要更改的線索。 使用前一點來了解如何解決問題。 在我的情況下，它改變了一條規則的路徑

在這些更改之后，我能夠將手動遷移的自定義規則集文件導入PMD插件4.0.0。

希望這可以幫助。

順便說一句：我發現4.0D版本的PMD插件非常多，所以我降級回3.2.6

Answer 5

除了別人說的話，你可能也必須找到這個：

net.sourceforge.pmd.rules.XPathRule

並將其替換為：

net.sourceforge.pmd.lang.rule.XPathRule

Answer 6

你為什么不使用Sonar Eclipse ？ 您不必擔心規則集的同步。
