如何使用离线插桩生成Jacoco联调报告？

构建工具：Maven

使用离线检测的原因：不可以删除Powermock

问题：故障安全和surefire都运行并生成报告。但是，Jacoco. exec是生成的，但Jacoco-it.exec不是。除了IT，离线检测、覆盖和报告都可以正常工作。

这是我使用的maven插件配置：

<plugin>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <executions>
        <execution>
            <id>default-instrument</id>
            <goals>
                <goal>instrument</goal>
            </goals>
        </execution>
        <execution>
            <id>default-restore-instrumented-classes</id>
            <goals>
                <goal>restore-instrumented-classes</goal>
            </goals>
        </execution>
        <execution>
            <id>default-report</id>
            <goals>
                <goal>report</goal>
            </goals>
        </execution>
        <execution>
            <id>default-report-integration</id>
            <goals>
                <goal>report-integration</goal>
            </goals>
        </execution>
    </executions>
</plugin>
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.16</version>
    <configuration>
        <systemPropertyVariables>
            <jacoco-agent.destfile>target/jacoco.exec</jacoco-agent.destfile>
        </systemPropertyVariables>
    </configuration>
</plugin>
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-failsafe-plugin</artifactId>
    <version>2.15</version>
    <executions>
        <execution>
            <id>integration-tests</id>
            <goals>
                <goal>integration-test</goal>
                <goal>verify</goal>
            </goals>
            <configuration>
                <skipTests>${skip.integration.tests}</skipTests>
            </configuration>
        </execution>
    </executions>
</plugin>

运行测试我使用maven清洁安装。

在测试执行结束时，我得到以下输出：

[INFO] 
[INFO] --- maven-failsafe-plugin:2.15:integration-test (integration-tests) @ elune ---
[INFO] Skipping execution of surefire because it has already been run for this configuration
[INFO] 
[INFO] --- jacoco-maven-plugin:0.7.8:report (default-report) @ elune ---
[INFO] Loading execution data file C:\Projects\elune\target\jacoco.exec

[INFO] 
[INFO] --- jacoco-maven-plugin:0.7.8:report-integration (default-report-integration) @ elune ---
[INFO] Skipping JaCoCo execution due to missing execution data file.

另一个可能的指针可能是类的去插桩发生在单元测试运行之后但在集成测试之前。但我不知道这是对还是错：

[INFO] 
[INFO] --- jacoco-maven-plugin:0.7.8:restore-instrumented-classes (default-restore-instrumented-classes) @ elune ---
[INFO] 
[INFO] --- maven-jar-plugin:2.6:jar (default-jar) @ elune ---

[INFO] 
[INFO] --- maven-failsafe-plugin:2.15:integration-test (default) @ elune ---
[INFO] Failsafe report directory: C:\Projects\elune\target\failsafe-reports

知道为什么Jacoco-it. exec没有出现吗？

我认为使用故障保护插件对集成测试进行检测是不成熟的。还原检测类目标默认为在联调阶段之前运行的准备包阶段：http://maven.apache.org/ref/3.3.9/maven-core/lifecycles.html-因此将该目标移动到集成后测试阶段可能就足够了：

<execution>
  <id>default-restore-instrumented-classes</id>
  <phase>post-integration-test</phase>
  <goals>
    <goal>restore-instrumented-classes</goal>
  </goals>
</execution>

这可能就足够了。否则，您可以更改surefire插件的包含模式以同时包含集成测试（如果这在您的情况下似乎合适）。

@rhinoceros. xn这是对我有用的插件配置。但是我使用mvn清洁安装来运行这个

        <plugin>
            <groupId>org.jacoco</groupId>
            <artifactId>jacoco-maven-plugin</artifactId>
            <executions>
                <execution>
                    <id>default-instrument</id>
                    <goals>
                        <goal>instrument</goal>
                    </goals>
                </execution>
                <execution>
                    <id>default-restore-instrumented-classes</id>
                    <phase>post-integration-test</phase>
                    <goals>
                        <goal>restore-instrumented-classes</goal>
                    </goals>
                </execution>
                <execution>
                    <id>default-report</id>
                    <goals>
                        <goal>report</goal>
                    </goals>
                </execution>
                <execution>
                    <id>default-report-integration</id>
                    <goals>
                        <goal>report-integration</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

命令行是：mvn清洁安装-Djaoco. version=0.7.8-DailOnError=false-Dmaven.test.不及格=true

我终于发现问题是我没有在maven-故障安全插件中添加配置Jacoco-agent. desfile。
