SonarQube上未显示自定义PMD Java规则违规

我正试图在SonarQube上运行我的自定义PMD规则，但到目前为止，没有成功 .

我创建了一个从sonar-pmd-plugin扩展的插件 . 在这个插件中，我有我的PMD规则集文件（custom_rules.xml），一个Sonar规则文件（pmd-extensions.xml）和我的自定义规则的Java类 .

SonarQube识别我的规则，并且我已在默认质量配置文件中启用它们 . 最后，当我对给定项目运行声纳分析时，我发现我的自定义规则已正确执行，并且他们在正在分析的项目中发现违规 .

但是，这些违规行为永远不会显示在SonarQube上的项目仪表板上 .

我正在使用的SonarQube版本是5.1.1 . PMD插件的版本是2.4.1 . 我为此问题创建了一个最小的示例，只有一个自定义规则 .

custom_rules.xml:

<?xml version="1.0" encoding="UTF-8"?>
<ruleset name="My custom rules" xmlns="http://pmd.sourceforge.net/ruleset/2.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://pmd.sourceforge.net/ruleset/2.0.0 http://pmd.sourceforge.net/ruleset_2_0_0.xsd">
    <rule 
        language="java"
        name="RuleJavaAssert"
        message="Avoid assert in production"
        class="br.gov.tcu.rules.RuleJavaAssert">
        <description>Production code should not use the assert command</description>
        <priority>3</priority>
    </rule>
</ruleset>

pmd-extensions.xml:

<rules>
    <rule>
        <key>br.gov.tcu.rules.RuleJavaAssert</key>
        <name>Avoid assert in production</name>
        <category name="Maintainability" />
        <priority>BLOCKER</priority>
        <description>Production code should not use the assert command</description>
        <configKey>br/gov/tcu/rules/custom_rules.xml/RuleJavaAssert</configKey>
    </rule>
</rules>

RuleJavaAssert.java:

public class RuleJavaAssert extends AbstractJavaRule {

    @Override
    public Object visit(ASTAssertStatement node, Object data) {
        System.err.println("Found violation");
        addViolation(data, node);
        return super.visit(node, data);
    }
}

AssertViolation.java:

public class AssertViolation {

    public static void testMethod() {
        String test = "test";
        assert(test != null);
    }   
}

在对包含“AssertViolation.java”类的项目运行时，控制台上SonarQube分析的输出：

从控制台消息“发现违规”我可以看到规则已正确执行，但SonarQube仍然显示0个问题 .

有什么想法吗？谢谢
