如何使Maven单元测试代码覆盖工作

Question

从属性中的pom

    <jacoco.it.execution.data.file>${project.build.directory}/coverage-reports/jacoco-it.exec</jacoco.it.execution.data.file>
    <jacoco.ut.execution.data.file>${project.build.directory}/coverage-reports/jacoco-ut.exec</jacoco.ut.execution.data.file>

这是我最后一次尝试，但pom变得越来越大，没有任何结果

与往常一样，在阅读了提供示例poms jacoco文档的文档后，解决方案变得很容易。

此配置文件：

    <profile>
        <id>test</id>
        <properties>
            <env>test</env>
            <gebEnv>test</gebEnv>
            <jacoco.skip>false</jacoco.skip>
            <maven.test.skip>false</maven.test.skip>
            <skip.unit.tests>false</skip.unit.tests>
        </properties>
    </profile>

在build部分中：

        <plugin>
            <groupId>org.jacoco</groupId>
            <artifactId>jacoco-maven-plugin</artifactId>
            <version>${jacoco.version}</version>
            <executions>
                <execution>
                    <goals>
                        <goal>prepare-agent</goal>
                    </goals>
                </execution>
                <execution>
                    <id>report</id>
                    <phase>prepare-package</phase>
                    <goals>
                        <goal>report</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

        <plugin>
            <groupId>org.jacoco</groupId>
            <artifactId>jacoco-maven-plugin</artifactId>
            <version>${jacoco.version}</version>
        </plugin>
