如何让 Cobertura 因代码覆盖率低而导致 M2 构建失败

如果行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。我一直在使用这本优秀书籍第455页提供的配置Java电动工具，但没有成功。这是我的项目 Maven 2 POM 的相关片段：

<build>
...
<plugins>
  <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>cobertura-maven-plugin</artifactId>
    <version>2.2</version>
    <configuration>
      <check>
        <!-- Per-class thresholds -->
        <lineRate>80</lineRate>
        <branchRate>80</branchRate>
        <!-- Project-wide thresholds -->
        <totalLineRate>90</totalLineRate>
        <totalBranchRate>90</totalBranchRate>
      </check>
      <executions>
        <execution>
          <goals>
            <goal>clean</goal>
            <goal>check</goal>
          </goals>
        </execution>
        <execution>
          <id>coverage-tests</id>
          <!-- The "verify" phase occurs just before "install" -->
          <phase>verify</phase>
          <goals>
            <goal>clean</goal>
            <goal>check</goal>
          </goals>
        </execution>
      </executions>
      <instrumentation>
        <excludes>
      <exclude>au/**/*Constants.*</exclude>
        </excludes>
        <ignores>
      <ignore>au/**/*Constants.*</ignore>
        </ignores>
      </instrumentation>
    </configuration>
  </plugin>
  ...
</plugins>
...
</build>

正如我所说，覆盖率报告工作正常，问题是，如果线路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，如果是的话，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。

我尝试过谷歌搜索和阅读 Cobertura 文档，但没有运气（至少可以说后者很少）。

据我所知，if the <haltOnFailure>element 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你所要求的。但实际上，这个元素默认为true如果您不指定它，那么您不必将其添加到您的配置检查。低于任何覆盖阈值的构建失败是（或至少应该是）默认行为。

EDIT:我做了一些进一步的测试haltOnFailure似乎在我的环境中按预期工作（插件的 Maven 2.2.1 和版本 2.3、2.2、2.1，即 Linux 上的 cobertura 版本 1.9.2、1.9、1.8）。我正在用下面的结果更新这个答案。

事实上，我已经添加了一个<execution>我的 pom 的元素。我可能误解了以下部分科贝图拉：检查的文档说“默认绑定到生命周期阶段：verify“但是，如果没有<execution>元素，科贝图拉：检查期间没有被触发verify我的构建阶段。下面是我用于 cobertura-maven-plugin 的设置：

<project>
  ...
  <build>
    ...
    <plugins>
      ...
      <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>cobertura-maven-plugin</artifactId>
        <version>2.3</version>
        <configuration>
          <check>
            <!--<haltOnFailure>true</haltOnFailure>--><!-- optional -->
            <!-- Per-class thresholds -->
            <lineRate>80</lineRate>
            <branchRate>80</branchRate>
            <!-- Project-wide thresholds -->
            <totalLineRate>90</totalLineRate>
            <totalBranchRate>90</totalBranchRate>
          </check>
        </configuration>
        <executions>
          <execution>
            <phase>verify</phase>
            <goals>
              <!--<goal>clean</goal>--><!-- works if uncommented -->
              <goal>check</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
</project>

运行时我得到以下结果mvn clean install在新生成的 Maven 项目上（带有mvn archetype:create）用上面提到的插件配置进行修补：

我没有使用maven 2.0.9进行测试，但是在我的机器上，haltOnFailure生成构建错误并停止构建。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。
