别不相信，就这么简单，如果运行不成功，那就是加入插件的parent pom.xml有可能是maven repsitry中的文件。  
在**parent pom.xml** 中的`<build>`中加入如下的插件：

<plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-surefire-plugin</artifactId>
                    <version>2.19.1</version>
                    <configuration>
                        <skipTests>false</skipTests>
                    </configuration>
                </plugin>
    <plugin>

                        </execution>
                        <execution>
                            <id>verify</id>
                            <goals>
                                <goal>verify</goal>
                            </goals>
                        </execution>
                    </executions>
                </plugin>
                <plugin>
                    <groupId>org.jacoco</groupId>
                    <artifactId>jacoco-maven-plugin</artifactId>
                    <version>0.7.9</version>
                    <configuration>
                        <destFile>target/coverage-reports/jacoco-unit.exec</destFile>
                        <dataFile>target/coverage-reports/jacoco-unit.exec</dataFile>
                    </configuration>
                    <executions>
                        <execution>
                            <id>jacoco-initialize</id>
                            <goals>
                                <goal>prepare-agent</goal>
                            </goals>
                        </execution>
                        <execution>
                            <id>jacoco-site</id>
                            <phase>test</phase>
                            <goals>
                                <goal>report</goal>
                            </goals>
                        </execution>
                    </executions>
                </plugin>

maven-surefire-plugin中的skiptest设置为false,用来运行单元测试。  
jacoco中的Execution用来对应maven的goal,可以是test,verify。还有集成测试的选项。  
运行 `mvn clean test -Dmaven.test.failure.ignore=true`  
生成的report 在 target /site/jacoco下，导航到文件下，去查看index.html就是了。
