# 在执行maven clean test后，结果提示：/* Skipping JaCoCo execution due to missing execution data file .*/ 在target目录下查找，发现没有生成suite文件。


2、解决方法（对Maven插件进行调整）

<!-- 对 maven-surefire-plugin 插件中的 configuration 下的 argLine 进行调整，调整如下： -->
	<argLine>${argLine} -Xmx2048m</argLine>



<!-- 生成单元测试覆盖率时，必须添加下列插件，下面是完整插件 -->

<!-- 引入maven-surefire-plugin插件 -->
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.19.1</version>
    <configuration>
        <!--suppress UnresolvedMavenProperty -->
        <argLine>${argLine} -Xmx2048m</argLine>
        <skipTests>false</skipTests>
        <includes>
            <include>**/*Test.java</include>
        </includes>
    </configuration>
</plugin>

<!-- 引入jacoco插件 -->
<plugin>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <version>0.8.3</version>
    <configuration>
        <includes>
            <!-- 对包路径中包含example的所有测试类进行jacoco统计 -->
            <include>**/example/**/*</include>
        </includes>
        <excludes>
            <!-- 排除包路径中包含util的所有测试类进行jacoco统计 -->
            <exclude>**/util/**/*</exclude>
        </excludes>
    </configuration>
    <executions>
        <execution>
            <goals>
                <goal>prepare-agent</goal>
            </goals>
        </execution>
        <execution>
            <id>report</id>
            <phase>test</phase>
            <goals>
                <goal>report</goal>
            </goals>
        </execution>
    </executions>
</plugin>
