无法在Eclipse中导入PMD规则集

Question

我想在我的Sonar配置文件的IDE（Eclipse）中使用相同的规则集。

我从声纳永久链接的PMD的XML规则集，并希望将其导入到我的PMD Eclipse插件，但是当我尝试这样做，“确定”按钮desactivated ...

有人可以帮我吗？

Answer 1

问题可能在于Sonar正在导出v4.x格式的规则集，并且您的Eclipse插件期望它们是v5.x格式。

尝试更改您的规则：

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

到

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

请注意：裁判属性。一个简单的查找和替换都可以为你工作。

Answer 2

为什么不使用Sonar Eclipse？您不需要担心规则集的同步。

Answer 3

Ivan Nikolov的回答是正确的。你的问题是规则集格式的不同版本。在我的情况下，我试图将从PMD插件版本3.2.6导出的规则集导入插件版本4.0.0。这里是我的发现：

• Ivan Nikolov提到的路径变化是所有规则都需要的。要小心，因为并不是所有规则都属于java（我也看到了XML的规则，...）。我对PMD并不那么深入，所以我不知道在哪个版本中引入了其他技术的规则。
• 为了与旧的自定义规则集文件进行比较，导出PMD插件4.0.0的默认规则集非常有用。这样你就可以解决下一个问题。
• 在你的行为被抛出的异常是不可视化的。该异常可以在工作区日志文件（/.metadata/.log）中看到。这可以给你一个线索，还有什么需要改变。使用上一点来了解如何解决问题。在我的情况下，它被改变路径一个规则从 到

这些变化，我能够导入手动迁移自定义的规则集文件到PMD插件4.0.0之后。

希望这会有所帮助。

BTW：我觉得版本4.0.0 PMD的插件非常错误，所以我降级到3.2.6

伊万·尼科洛夫的建议帮助我，但我不得不改变也从一个规则：

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

到

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

下面是它为我工作与PMD-插件4.0.2声纳我PMD的配置文件。：

Answer 5

除了别人怎么说，你也必须找到这样的：

net.sourceforge.pmd.rules.XPathRule 

并以此替换：

net.sourceforge.pmd.lang.rule.XPathRule 

Answer 6

我不得不把语言添加到我的XPath规则也是如此，例如：

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