在 maven 中配置 JaCoCo 时出现问题

java maven jacoco jacoco-maven-plugin

2022-09-02 10:29:59

我正在尝试通过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>

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

未能在项目 ##上执行 goal org.jacoco：jacoco-maven-plugin：0.7.201409121644：check （default-cli） on project ##： goal org.jacoco：jacoco-maven-plugin：0.7.2.201409121644：check 丢失或无效 -> [Help 1]

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，这看起来像是0.6.3以上任何版本的有效配置，甚至最初是从下面的链接中找到的他们自己的示例中获取的（我刚刚删除了除检查目标之外的所有内容）：

如果我使用该选项运行，我将获得以下堆栈跟踪：-X

我做错了什么？

答案 1

这是因为您启动 maven 时有明确的目标：

mvn ... jacoco:check

像这样运行，里面的部分没有被阅读;要使其正常工作，请使用目标绑定到的默认 maven 阶段，即<configuration><execution>jacoco:checkverify

mvn clean verify

或者，或者，（但我现在不能自己尝试，我不是100%确定），尝试在执行id中使用前缀，例如：default-

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

答案 2

我有同样的问题。为了解决这个问题，我在覆盖率检查执行中添加了相位标签：

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

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