Tomcat7 Maven插件和JaCoCo

Question

以下是我的POM中的一些相关片段：

    <version>2.1</version>
    <configuration>
        <systemProperties>
            <!-- as expected, this system property doesn't work since Tomcat is embedded, but this is the type of config I'm looking for -->
            <JAVA_OPTS>-javaagent:${project.build.directory}/${jacoco.jar}=destfile=${project.build.directory}/jacoco.exec,append=true</JAVA_OPTS>
        </systemProperties>
    </configuration>
    <executions>
        <execution>
            <id>tomcat-startup</id>

            <phase>post-integration-test</phase>
        </execution>
    </executions>
</plugin>

版本:Maven 3.0.4、Tomcat Maven Plugin2.1、Jacoco 0.6.2.201302030002、Java7

Answer 1

我知道自从这个问题发布以来已经有一段时间了，但我觉得答案并没有真正解决问题的根源。如果您在这些插件中运行测试，代码覆盖率可能与failsafe或surefire一起工作。但是，如果您只是想用jacoco监视tomcat，以获得覆盖率报告，那么当前的信息并不能提供这一点。我发现tomcat7-maven-plugin不允许您通过简单地提供java_opts来为jacoco注入-javaagent。切换到货物，我能够这样做。

重要的部分是：

1. org.jacoco ... jacoco.agent.itargline
2. ${jacoco.agent.itargline},output=tcpserver,port=6300
