无法设置不存在的属性PMD sonarqube插件

Question

我已经为sonarqube 4.5.1版创建了一个自定义插件。这个插件包含一个新的自定义规则，基于PMD。我遵循了一些例子（https://github.com/SonarSource/sonar-examples/tree/master/plugins），以正确的方式开发这个插件，但我一直在构建我必须用声纳检查的项目，我有同样的错误：java.lang.IllegalArgumentExctive：无法在规则MaximummetodsCountCheck规则上设置不存在的属性'maxAuthorisedmetodsCount'我的声纳安装也安装了声纳-pmd-plugin v2.2和声纳-java-plugin v2.4。下面的代码会产生错误

extensions.xml

<?xml version="1.0" encoding="UTF-8"?>
<rules>
    <rule>
    <key>MaximumMethodsCount</key>
    <name>Maximum Methods Count Check</name>
    <description>Massimo numero di metodi autorizzati per classe</description>

    <!-- path to definition -->
    <configKey>rulesets.xml/MaximumMethodsCountCheckRule</configKey>

    <!-- Default priority ("severity"). It can be changed while activating the rule in Quality profile -->
    <!-- Possible values are: INFO, MINOR, MAJOR, CRITICAL, BLOCKER. Default value is MAJOR -->
    <priority>MAJOR</priority>

有人知道如何修复错误吗？请帮忙！非常感谢你！！！

Answer 1

您需要在您的MaximummetodsCountCheck类的构造函数中调用定义属性描述符。

（我通过查看提供的一些具有属性的规则，例如NPathComplexityRule，了解到了这一点）
