Question

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。我一直在使用优秀书籍Java Power Tools的第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：

<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，如果是这样，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。

我已经尝试使用谷歌搜索和阅读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<haltOnFailure>元素设置为true且任何指定的检查失败，那么Cobertura将导致构建失败这就是你要求的。但实际上，如果您未指定该元素，则此元素默认为true，因此您无需将其添加到configuration checks。使构建低于任何覆盖阈值是（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。和版本2.3,2.2,2.1的插件即版本Linux上的cobertura的1.9.2,1.9,1.8）。我正在用以下结果更新这个答案。

实际上，我已经在我的pom中添加了<execution>元素。我可能会错误地解释cobertura:check文档中“默认绑定到生命周期阶段：verify ”的部分，但是没有<execution>元素，cobertura:check在我的构建的验证阶段未触发。在我用于cobertura-maven-plugin的设置下面：

<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>

在使用上述插件配置修补新生成的maven项目（mvn clean install）上运行mvn archetype:create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生成了BUILD ERROR并停止了构建。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＆lt; check /＆gt;配置。

<haltOnFailure>true</haltOnFailure>

Answer 3

mvn全新安装-Dcobertura.skip = true
