【问题描述】：

在我的 SonarQube 分析中，我可以找到以下错误：

WARN: The class 'com.mycompany.bla.BlaTest' could not be matched to its original source file. It might be a dynamically generated class.
WARN: Failed to load the class file metadata
org.sonar.plugins.findbugs.resource.ClassMetadataLoadingException: ASM failed to load classfile metadata

我发现错误发生在源位于“testsrc/com/mycompany/...”下的单元测试文件上。编译后的testclass位于"classes"

下

所以项目结构是：

myProject
    |- src
    |- testsrc
    |- classes

在我的 sonar-project.properties 我有以下配置：

sonar.tests=testsrc
sonar.sources=src

这里的正确解决方案是什么？排除测试类被 FindBugs 分析或将 testsrc 文件夹添加到分析的源？

标签： sonarqube findbugs sonarqube-scan

【解决方案1】：

诀窍是将 findbugsexclude.xml 添加到 sonarqube：

sonar.findbugs.excludesFilters=findbugsexclude.xml

并排除测试类中的所有测试类和内部类：

<?xml version="1.0" encoding="UTF-8"?>
<FindBugsFilter>
    <Match>
        <Class name="~.*Test$"/>
    </Match>
    <Match>
        <Class name="~.*Test\$.*$"/>
    </Match>
</FindBugsFilter>
