在maven中配置JaCoCo时出错

Question

我试图通过Maven做一个简单的JaCoCo报告，但我总是得到同样的错误。这是我的插件的一个片段。

<plugin>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <version>0.7.2.201409121644</version>
    <executions>
        <execution>
            <id>jacoco-check</id>
            <goals>
                <goal>check</goal>
            </goals>
            <configuration>
                <rules>
                    <rule>
                        <element>PACKAGE</element>
                        <limits>
                            <limit>
                                <counter>LINE</counter>
                                <value>COVEREDRATIO</value>
                                <minimum>0.01</minimum>
                            </limit>
                        </limits>
                    </rule>
                </rules>
            </configuration>
        </execution>
    </executions>
</plugin>

当我运行mvn净安装雅各科：检查时，我得到以下信息

无法执行目标org.jacoco：Jacoco-maven-plugin：0.7.2.201409121644：检查（default-cli）项目 ###########: 目标org.jacoco的参数'规则'：Jacoco-maven-plugin：0.7.2.201409121644：检查丢失或无效-

我尝试将版本从0.6.3更改为0.7.2以及介于两者之间的每个版本。据我所知，对于0.6.3以上的任何版本，这看起来都是有效的配置，甚至最初取自以下链接中的示例（我刚刚删除了除检查目标之外的所有内容）：

http://www.eclemma.org/jacoco/trunk/doc/maven.html

如果使用-X选项运行，则会得到以下堆栈跟踪：

我做错了什么？

Answer 1

我也有同样的问题。为了解决这个问题，我在覆盖率检查执行中添加了阶段标记:

<id>coverage-check</id>
<phase>test</phase>
<goals>
     <goal>check</goal>
</goals>

现在，每次运行“mvn clean package”命令时，都会执行覆盖率检查。

Answer 2

这是因为您启动maven的目标很明确：

mvn ... jacoco:check

像这样运行，

mvn clean verify

或者，（但我现在无法亲自尝试，我也不能100%确定），尝试在执行ID中使用default-前缀，例如：

   <execution>
        <id>default-jacoco-check</id>
        <goals>
            <goal>check</goal>
        </goals>
        [...]
   </execution>
