如何使用PowerMock和Jacoco Offline Instrumentation从Maven Multiproject获得SonarQube的覆盖范围

Question

我正在构建Maven多项目。 我正在使用Powermock来模拟用于编写单元测试用例的类。 因此，为了获得jacoco的覆盖范围，我使用了Jacoco离线检测工具，并设置了sonar.dynamicAnalysis = reuseReports来获取声纳覆盖范围。 当我尝试这样做时，我遇到了Jacoco和Sonar抛出的错误：

我不确定jacoco为什么要再次尝试上课以获取声纳覆盖范围。 我被这个问题困扰了一段时间。 任何帮助都会很棒。

Answer 1

根据http://www.jacoco.org/jacoco/trunk/doc/instrument-mojo.html ：

执行离线检测。 请注意，执行测试后，您必须在“ restore-instrumented-classes”目标的帮助下还原原始类。

already instrumented异常消息具有误导性，但是恰恰是在尝试分析检测到的类而不是原始类时才产生此消息。

Answer 2

我不确定您的情况如何，但是我已经使用powermock-module-javaagent通过powermock-module-javaagent生成了PowerMock覆盖范围。

只要确保将powermock代理放在jacoco代理之后即可：

<artifactId>maven-surefire-plugin</artifactId>
            <configuration>
                <useSystemClassLoader>true</useSystemClassLoader>
                <argLine>${jacocoArgLine} -javaagent:${settings.localRepository}/org/powermock/powermock-module-javaagent/${powermock.version}/powermock-module-javaagent-${powermock.version}.jar -noverify</argLine>
...

如果要查看示例，请看以下项目： https : //github.com/jfcorugedo/sonar-scanner

在这里，您可以看到声纳考虑了静态方法和PowerMock模拟的new语句：

如果要模拟new语句，请确保使用PowerMockRule而不是PowerMockRunner 。
