在 Maven 站点中包含 Jacoco 报告

问题描述 投票:0回答:3

我已经将

jacoco-maven-plugin
集成到我的项目中,基于这个优秀的指南:http://www.petrikainulainen.net/programming/maven/creating-code-coverage-reports-for-unit-and-integration-使用 jacoco-maven-plugin 进行测试/

Jacoco 插件运行良好。但是,

maven-site-plugin
网站中不包含 Jacoco 报告。更具体地说:“项目报告”部分没有列出 Jacoco 报告。 Jacoco 报告本身可在
target/site/jacoco-ut
target/site/jacoco-it
目录中找到。

这就是我所做的(到目前为止还没有成功)。

首先,将

jacoco-maven-plugin
作为插件包含在我的
build
pom.xml
部分中,如上面引用的指南中所述。我正在使用 Jacoco 版本 0.6.4.201312101107。

<plugin>
  <groupId>org.jacoco</groupId>
  <artifactId>jacoco-maven-plugin</artifactId>
  <version>${jacoco.plugin.version}</version>
  <executions>
    <!-- scissors... -->
    <!-- report goal is bound to the pre-site phase -->
  </executions>
</plugin>

其次,将

jacoco-maven-plugin
包含在我的
report
pom.xml
部分:没有成功。

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

第三,尝试在

reportsets
部分中的
jacoco-maven-plugin
中添加
report
部分:没有成功。

<plugin>
  <groupId>org.jacoco</groupId>
  <artifactId>jacoco-maven-plugin</artifactId>
  <version>${jacoco.plugin.version}</version>
  <reportSets>
    <reportSet>
      <reports>
        <report>report</report>
      </reports>
    </reportSet>
  </reportSets>
</plugin>

任何人都可以帮我制作

maven-site-plugin
引用 Jacoco 在网站“项目报告”部分生成的覆盖率报告吗?

maven plugins jacoco

我发现 jacoco 非常棘手,下面的配置对我有用,我把它从博客中的零碎组合起来 在属性中

<jacoco.reportPath>${main.basedir}/target/jacoco.exec</jacoco.reportPath>
    <jacoco.itReportPath>${main.basedir}/target/jacoco-it.exec</jacoco.itReportPath>

构建内部

我所做的是将两个执行文件(

jacoco-ut.exec
jacoco-it.exec
)合并到一个名为
jacoco.exec
的文件中,然后将该文件设置为插件的
dataFile

首先,让我们定义这些属性:

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

然后,连同生成报告的配置一起,包含此代码片段以创建合并文件:

<plugin>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <version>${jacoco-plugin.version}</version>
    <executions>
        ...
        <execution>
            <id>merge</id>
            <phase>verify</phase>
            <goals>
                <goal>merge</goal>
            </goals>
            <configuration>
                <fileSets>
                    <fileSet>
                        <directory>${project.build.directory}/coverage-reports</directory>
                        <includes>
                            <include>*.exec</include>
                        </includes>
                    </fileSet>
                </fileSets>
                <destFile>${jacoco.execution.data.file}</destFile>
            </configuration>
        </execution>
        <execution>
            <id>report-merge</id>
            <phase>verify</phase>
            <goals>
                <goal>report</goal>
            </goals>
            <configuration>
                <dataFile>${jacoco.execution.data.file}</dataFile>
            </configuration>
        </execution>
    </executions>
</plugin>

最后,在

reporting
部分配置插件以从该合并文件生成报告:

<reporting>
    <plugins>
        <plugin>
            <groupId>org.jacoco</groupId>
            <artifactId>jacoco-maven-plugin</artifactId>
            <configuration>
                <dataFile>${jacoco.execution.data.file}</dataFile>
            </configuration>
            <reportSets>
                <reportSet>
                    <reports>
                        <report>report</report>
                    </reports>
                </reportSet>
            </reportSets>
        </plugin>
        ...
    </plugins>
</reporting>

简短回答

您已经非常接近解决方案了,但是

reportSets
不是
build -> plugins -> plugin
的属性,而是
reporting -> plugins -> plugin
的属性。

因此,为了在生成的 Maven 站点中包含 JaCoCo 报告,您将指定 JaCoCo Maven 插件两次:

  1. build -> plugins -> plugin
    下启用 Java 代理(无需在此处添加
    report
    目标)。
  2. reporting -> plugins -> plugin
    指定
    reportSet

最简单的片段是:

    <!-- goes directly under tag "project" -->
    <reporting>
        <plugins>
            <plugin>
                <groupId>org.jacoco</groupId>
                <artifactId>jacoco-maven-plugin</artifactId>
                <version>${jacoco.plugin.version}</version>
                <reportSets>
                    <reportSet>
                        <reports>
                            <report>report</report>
                        </reports>
                    </reportSet>
                </reportSets>
            </plugin>
        </plugins>
    </reporting>

长答案

虽然也可以通过自定义

maven-site-plugin
的输出(例如通过
site.xml
)手动添加 JaCoCo 报告的链接,但这不是最简单的方式,也不是预期的方式。 JaCoCo 的
ReportMojo
实现了
MavenMultiPageReport
,这允许
maven-site-plugin
将其检测为报告插件。然而,仅通过阅读文档,它的工作原理还远不清楚。

report
下指定
build -> plugins
目标时,
maven-site-plugin
不知道 JaCoCo 报告是否存在。仅当在
reporting -> plugins
下给出时,它被称为
report
而不是
goal
,尽管它实际上是同一件事。此处指定时,(报告)插件将通过
maven-site-plugin
间接启动(而不是直接通过 Maven 构建)。然而,要使报告包含必要的信息,JaCoCo 输出必须在报告之前存在,并且只有当目标
prepare-agent
(或用于集成测试的
prepare-agent-integration
)已添加到
jacoco-maven-plugin 下的 
build -> plugins
 时才会出现这种情况。 
。唷! 😅

JaCoCo 有三个报告(可以双向触发):

  • report
    对于单个 Maven 项目
  • report-aggregate
    用于多模块 Maven 项目
  • report-integration
    用于集成测试

所有这些都会被

reportSet
自动检测到(并且在省略
maven-site-plugin
的情况下也会执行):

[INFO] --- site:3.12.1:site (default-site) @ java-playground ---
[INFO] configuring report plugin org.jacoco:jacoco-maven-plugin:0.8.11
[INFO] 3 reports detected for jacoco-maven-plugin:0.8.11: report, report-aggregate, report-integration

长话短说,一个简单的单个 Maven 项目的完整 pom.xml 可能如下所示:
