maven-surefire-plugin，jacoco-maven-plugin显示没有报道

我正在使用带有maven的maven-surefire-plugin版本2.17 .

我正在使用jacoco-maven-plugin来分析我的junit测试：

我在我的pom.xml中设置的jacoco插件如下所示：

<plugin>
            <groupId>org.jacoco</groupId>
            <artifactId>jacoco-maven-plugin</artifactId>
            <version>0.7.6.201602180812</version>
            <executions>
                <execution>
                    <id>agent-for-ut</id>
                    <goals>
                        <goal>prepare-agent</goal>
                    </goals>
                    <configuration>
                        <destFile>${sonar.jacoco.reportPath}</destFile>
                        <append>true</append>
                    </configuration>
                </execution>
                <execution>
                    <id>post-unit-test</id>
                    <goals>
                        <goal>report</goal>
                    </goals>
                    <configuration>
                        <dataFile>${sonar.jacoco.reportPath}</dataFile>
                        <outputDirectory>${project.reporting.outputDirectory}/jacoco-ut</outputDirectory>
                    </configuration>
                </execution>
            </executions>
        </plugin>

我在src / main / java / something / excel下有一个类，如下所示：

package something.excel;

public class VDHTCStyle
{
    public int doSomething() {
        int i=0;
        return i+7;
    }
}

我在src / test / java / something / excel下的测试类看起来像这样：

package something.excel;

import org.junit.Before;
import org.junit.Test;

import static org.junit.Assert.assertEquals;

public class VDHTCStyleStyleTest
{
    private VDHTCStyleStyle vDHTCStyleStyle;

    @Before
    public void setUp()
    {
        vDHTCStyleStyle = new VDHTCStyleStyle();
    }

    @Test
    public void shouldDoSomething() {
        int something = vDHTCStyleStyle.doSomething();
        assertEquals(something, 7);
    }

}

当我用它运行时

mvn clean install

我在日志中看到了这个：

[INFO] --- maven-surefire-plugin:2.17:test (default-test) @ xxxxx ---

现在，如果我查看生成的jacoco-ut报告文件，我会看到如下内容：

GROUP,PACKAGE,CLASS,INSTRUCTION_MISSED,INSTRUCTION_COVERED,BRANCH_MISSED,BRANCH_COVERED,LINE_MISSED,LINE_COVERED,COMPLEXITY_MISSED,COMPLEXITY_COVERED,METHOD_MISSED,METHOD_COVERED
Module: xxx,something.excel,VDHTCStyleStyle,9,0,0,0,3,0,2,0,2,0

据我了解，它认为没有涵盖任何行，说明，分支或方法 .

为什么？救命 ：）
