如何让Cobertura失败M2构建以实现低代码覆盖率

如果线或分支覆盖率低于给定阈值，我正在尝试将WAR项目构建配置为失败。 我一直在使用优秀的Java Power Tools书籍第455页提供的配置，但没有成功。 这是我的项目Maven 2 POM的相关片段：

 ...   org.codehaus.mojo cobertura-maven-plugin 2.2    80 80  90 90     clean check    coverage-tests  verify  clean check      au/**/*Constants.*   au/**/*Constants.*     ...  ...  

正如我所说，覆盖率报告工作正常，问题是如果线或分支覆盖率低于我指定的阈值，“安装”目标不会失败。 有没有人有这个工作，如果有的话，你的POM是什么样的，你使用的是哪个版本的Cobertura和Maven？ 我正在使用Maven 2.0.9和Cobertura 2.2。

我已经尝试过谷歌搜索和阅读Cobertura文档，但没有运气（后者至少可以说是稀疏）。

Answer 1

据我所知， 如果元素设置为true并且任何指定的检查失败，那么Cobertura将导致构建失败 ，这就是您所要求的。 但实际上，如果您没有指定它，则此元素默认为true ，因此您不必将其添加到配置检查中 。 在任何覆盖阈值以下构建失败是（或至少应该是）默认行为。

编辑：我做了一些进一步的测试， haltOnFailure似乎在我的环境中正常工作（Maven 2.2.1。和插件版本2.3,2.2,2.1，即Linux上的cobertura版本1.9.2,1.9,1.8）。 我正在使用下面的结果更新此答案。

实际上，我已经在我的pom中添加了一个元素。 我可能误解了cobertura的一部分：检查文档说它“ 默认绑定到生命周期阶段： verify ”但是，如果没有元素， cobertura：在我的构建的validation阶段没有触发检查 。 在我用于cobertura-maven-plugin的设置下面：

  ...  ...  ...  org.codehaus.mojo cobertura-maven-plugin 2.3     80 80  90 90     verify   check        

在使用上面提到的插件配置修补的新生成的maven项目（使用mvn archetype:create ）上运行mvn clean install时，我得到以下结果：

我没有使用maven 2.0.9进行测试，但是在我的机器上， haltOnFailure生成一个BUILD ERROR并停止构建。 我没有看到您的插件配置有任何差异，我无法重现您描述的行为。

Answer 2

将以下内容添加到配置中。

 真

Answer 3

mvn clean install -Dcobertura.skip = true
