wso2 - 集成测试模块中的 FindBugs Maven 插件

Question

我正在用 Java 编写测试用例。我想集成 FindBugs Maven 插件来提高测试类中的代码质量。我已将 FindBugs Maven Plugin 添加到测试模块的 POM 文件中。我可以成功创建 FindBugs XML 文档，但即使 FindBugs 在我的代码中发现了一些错误，构建也会成功。

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>

FindBugs Maven 插件的行为有所不同，具体取决于是否 src/main/java是否为空。如果它不存在(模块仅用于测试并且仅包含 src/test/java )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

这是 FindBugs Maven 插件中的错误。我已将其报告为 gleclaire/findbugs-maven-plugin#33 。在 FindbugsViolationCheckMojo有一个 if 检查“主”类是否存在，如果不存在，插件假设没有分析任何内容，并且不会调用导致构建失败的代码。

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
