cobertura-maven-plugin与FindBugs冲突

时间：2015-04-12 20:43:54

标签： maven findbugs cobertura

将cobertura-maven-plugin从 2.6 更新为 2.7 后，Cobertura插件与FindBugs插件发生冲突。 FindBugs插件检测到cobertura检测代码中的错误：

[INFO] Incorrect lazy initialization of static field pl.chilldev.sites.commons.ErrorCode.__cobertura_counters in pl.chilldev.sites.commons.ErrorCode.__cobertura_init() [pl.chilldev.sites.commons.ErrorCode] In ErrorCode.java

（当Cobertura插件verison设置为2.6时，一切正常）

以防万一，FindBugs插件版本为3.0.1。

是否可以设置这些插件以某种方式协同工作？

编辑1（pom.xml）

这是主项目目录的pom.xml（子模块仅包含依赖项列表）：

Cobertura 2.7改变project.build.outputDirectory以生成集成测试报告（2.7中引入的新报告）。在下一步中，Findbugs检查的违规行为不仅仅是编译的类，而是检测的。

见bug：

http://jira.codehaus.org/browse/MCOBERTURA-203

作为解决方法，您可以覆盖classFilesDirectory：

...
<build>
...
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>findbugs-maven-plugin</artifactId>
            <version>3.0.1</version>
            <configuration>
                <effort>Max</effort>
                <threshold>Low</threshold>
                <classFilesDirectory>${project.build.outputDirectory}</classFilesDirectory>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>check</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
...
</build>
...

另一种解决方案是跳过集成测试报告，仅继续进行单元测试报告：

如果强制findbugs在“编译”阶段而不是“测试”阶段运行，它将导致findbugs在cobertuar检测代码之前运行，从而解决了Mateusz Balbus所描述的问题。这个findbugs maven配置适用于我：

答案 2 :(得分：-2)

首先需要了解您的项目结构。

我认为您的问题可以通过使用传递依赖来解决，但不确定。

它做了两件事。

  1. 为子模块/子项目中的依赖项设置默认版本
  2. 覆盖传递依赖项的版本

    3. 它会覆盖传递依赖项中的指定值。

    enforcer插件不会忽略 dependencyManagement 。但由于传递依赖的版本在上线之前被更改，因此无法识别出这种差异。

    这是一篇很好的文章：你可以通过它： http://andydennie.com/2012/08/02/maven-enforcer-plugin-vs-dependencymanagement/

    感谢。
