无法在maven中配置JaCoCo

Question

我试图通过Maven做一个简单的JaCoCo报告,我一直得到同样的错误.这是我的插件的片段.

<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>

当我跑步时,mvn clean install jacoco:check我得到以下内容

无法执行目标org.jacoco:jacoco-maven-plugin:0.7.2.201409121644:check(default-cli)on project ###########:目标org.jacoco的参数'rules':jacoco -maven-plugin:0.7.2.201409121644:检查丢失或无效 - > [帮助1]

我已经尝试将版本从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,这看起来像0.6.3以上的任何版本的有效配置,甚至最初取自他们在下面的链接中找到的示例(我刚刚删除除检查目标之外的所有内容):

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

如果我运行-X选项,我得到以下堆栈跟踪:

我究竟做错了什么？

Answer 1

这是因为您使用明确的目标启动maven:

mvn ... jacoco:check

像这样跑,<configuration>里面的部分<execution>不读; 为了使它工作,使用jacoco:check目标所绑定的默认maven阶段,即verify

mvn clean verify

或者,或者,(但我现在不能自己尝试这个并且我不是100%确定),尝试default-在执行ID中使用前缀,例如:

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