JaCoCo Maven 插件生成 XML 格式的報告

Question

我正在使用 maven-jacoco-plugin 生成測試覆蓋率。 使用的版本是 0.8.7。

運行mvn test命令時，它會生成 exec 格式的報告。

<plugin>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <version>${jacoco-maven-plugin.version}</version>
    <configuration>
        <formats>XML</formats>
    </configuration>
    <executions>
        <!-- Prepares the property pointing to the JaCoCo runtime agent which is passed as VM argument when Maven
            the Surefire plugin is executed. -->
        <execution>
            <id>jacoco-initialize-unit-test</id>
            <goals>
                <goal>prepare-agent</goal>
                <goal>report</goal>
            </goals>
            <configuration>
                <outputDirectory>${project.build.directory}/../target/site/jacoco-aggregate</outputDirectory>
                <!--<destFile>${project.build.directory}/../../target/coverage-reports/jacoco-ut.exec</destFile>-->
                <append>true</append>
                <propertyName>jacoco.agent.argLine</propertyName>
            </configuration>
        </execution>
        <execution>
            <id>jacoco-initialize-integration-test</id>
            <phase>pre-integration-test</phase>
            <goals>
                <goal>prepare-agent</goal>
            </goals>
            <configuration>
                <destFile>${project.build.directory}/../../target/coverage-reports/jacoco-it.exec</destFile>
                <append>true</append>
                <propertyName>jacoco.agent.argLine</propertyName>
            </configuration>
        </execution>
        <execution>
            <id>jacoco-merge</id>
            <phase>post-integration-test</phase>
            <goals>
                <goal>merge</goal>
            </goals>
            <configuration>
                <fileSets>
                    <fileset>
                        <directory>${project.build.directory}/../../target/coverage-reports/</directory>
                        <includes>
                            <include>*.exec</include>
                        </includes>
                    </fileset>
                </fileSets>
                <destFile>${project.build.directory}/../../target/coverage-reports/jacoco.exec</destFile>
            </configuration>
        </execution>
        <!-- Ensures that the code coverage report for integration tests is created after all tests have been
            run. -->
        <execution>
            <id>jacoco-report</id>
            <phase>verify</phase>
            <goals>
                <goal>report-aggregate</goal>
            </goals>
            <configuration>
                <outputDirectory>${project.build.directory}/../target/site/jacoco-aggregate</outputDirectory>
            </configuration>
        </execution>
    </executions>
</plugin>

當我嘗試在使用 XML 下添加配置標簽時，它給出了一個錯誤

無法解析 mojo org.jacoco:jacoco-maven-plugin:0.8.8:report-aggregate 的配置參數格式：無法將 java.lang.String 類型的值為“XML”的配置條目“格式”分配給類型的屬性java.util.List -> [幫助 1]

任何人都可以建議如何繼續前進嗎？

您必須添加一個格式節點：

<formats>
    <format>XML</format>
</formats>

在 GitHub 上，您可以找到示例。 像這樣： https ://github.com/jacoco/jacoco/blob/master/jacoco-maven-plugin.test/it/it-report-select-formats/pom.xml
