spring boot多模块包

我正在尝试使用Maven将Spring Boot打包为多个模块，这里是我的主模块pom.xml：

<modules>
    <module>my-data-services</module>
    <module>my-message-services</module>
    <module>my-common</module>
</modules>
<groupId>com.my</groupId>
<artifactId>my-multi-services</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>pom</packaging>

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.4.2.RELEASE</version>
</parent>


<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <java.version>1.8</java.version>
</properties>
<dependencyManagement>....</dependencyManagement>
<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

我的常见pom.xml：

<parent>
    <artifactId>my-multi-services</artifactId>
    <groupId>com.my</groupId>
    <version>1.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>my-common</artifactId>
<packaging>jar</packaging>
<dependencies>....</dependencies>

和my-data-services pom.xml：

<parent>
    <artifactId>my-multi-services</artifactId>
    <groupId>com.my</groupId>
    <version>1.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>my-data-services</artifactId>

<dependencies>

    <dependency>
        <groupId>com.my</groupId>
        <artifactId>my-common</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

my-common 模块只是一个常见的utils lib而不是一个可运行的模块，但是当我尝试 mvn clean package 时，异常抛出如下：

Execution default of goal org.springframework.boot:spring-boot-maven-p
lugin:1.4.2.RELEASE:repackage failed: Unable to find main class

然后我添加一个主类，这个模块可以打包，但它不是一个lib jar，它就像一个runnable spring boot jar

-BOOT-INF
 |
 -META-INF
 |
 -org

并抛出异常

Failed to execute goal org.apache.maven.plugins:maven-compiler- plugin:3.1:compile (default-compile) on project my-data-services: Compilation failure: Compilation failure: package com.my.common.utils does not exist ;

com.my.common.utils 在模块中 my-common

我如何解决这个问题，并在spring boot多模块项目中，如何打包一个没有BOOT-INF的常见utils lib
