Question

我正在编写用Java编写测试用例。我想集成FindBugs Maven插件来提高我在测试类中的代码质量。我已将FindBugs Maven插件添加到测试模块的POM文件中。我可以成功创建FindBugs XML文档但是构建成功甚至FindBugs在我的代码中发现了一些错误。

有人可以指导我吗？

我的配置：

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>findbugs-maven-plugin</artifactId>
    <configuration>
        <effort>Max</effort>
        <threshold>Low</threshold>
        <xmlOutput>true</xmlOutput>
        <findbugsXmlOutputDirectory>${project.build.directory}/findbugs</findbugsXmlOutputDirectory>
        <includeTests>true</includeTests>
        <failOnError>true</failOnError>
    </configuration>
    <executions>
        <execution>
            <id>analyze-compile</id>
            <phase>compile</phase>
            <goals>
                <goal>check</goal>
            </goals>
        </execution>
    </executions>
</plugin>

根据src/main/java是否为空，FindBugs Maven插件的行为会有所不同。如果它不存在（模块是仅测试且仅包含src/test/java），则构建不会失败：

[INFO] --- findbugs-maven-plugin:3.0.3:findbugs (findbugs) @ findbugs-fail-build ---
[INFO] Fork Value is true
     [java] Warnings generated: 1
[INFO] Done FindBugs Analysis....
[INFO] 
[INFO] <<< findbugs-maven-plugin:3.0.3:check (findbugs) < :findbugs @ findbugs-fail-build <<<
[INFO] 
[INFO] --- findbugs-maven-plugin:3.0.3:check (findbugs) @ findbugs-fail-build ---

[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------

当模块中有一些生产代码（src/main/java不为空）时，构建失败：

[INFO] --- findbugs-maven-plugin:3.0.3:findbugs (findbugs) @ findbugs-fail-build ---
[INFO] Fork Value is true
     [java] Warnings generated: 1

FindBugs Maven插件中的 bug 。我已将其报告为gleclaire/findbugs-maven-plugin#33。在FindbugsViolationCheckMojo中，有一个if检查'main'类是否存在，如果不存在，插件假定没有分析任何内容，并且没有调用构建失败的代码。

有两种解决方法：

添加 <classFilesDirectory>${project.build.testOutputDirectory}</classFilesDirectory> 配置
将任何代码添加到src/main/java

集成测试模块中的FindBugs Maven插件
