如果行或分支覆盖范围低于给定的阈值，我试图将我的WAR项目构建配置为失败。我一直在使用Java Power Tools一书中第455页提供的配置，但是没有成功。这是我的项目的Maven 2 POM的相关代码段：
<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>
就像我说的那样，覆盖率报告工作正常，问题在于，如果行或分支覆盖率低于我指定的阈值，则“安装”目标不会失败。有人能正常工作吗？如果是这样，那么您的POM是什么样的？您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。
我尝试了Googling并阅读了Cobertura文档，但没有运气（至少可以说后者很少）。
据我所知， 如果将该<haltOnFailure>元素设置为true，并且任何指定的检查均失败，那么Cobertura将导致构建失败，这正是您所要求的。但是实际上，true如果您未指定此元素，则默认为，因此 不必 将其添加到配置检查中。默认版本是（或至少应该是）使构建低于任何覆盖率阈值。
<haltOnFailure>
true
编辑： 我做了一些进一步的测试，并且haltOnFailure似乎在我的环境（Maven 2.2.1。以及插件的2.3、2.2、2.1版，即Linux上的cobertura的1.9.2、1.9、1.8版）上按预期工作。我正在用以下结果更新此答案。
haltOnFailure
实际上，我已经<execution>在pom中添加了一个元素。我可能会误解了cobertura：check的文档中说“ 默认绑定到生命周期阶段：verify ”的<execution>部分，但是，没有该元素，在我的构建的 验证 阶段未触发cobertura：check。在我用于cobertura-maven-plugin的设置下面： __
<execution>
verify
<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>
mvn clean install在mvn archetype:create使用上述插件配置修补的新生成的Maven项目（带有）上运行时，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生成了一个BUILD ERROR并停止了构建。我没有发现您的插件配置有任何差异，也无法重现您描述的行为。
