idea创建maven项目

1.创建父模块
File->New ->Project->Maven

GroupId: com.sky.cloud
Artifactid: sky-cloud-starter-parent
Version: 1.0-SNAPSHOT

• 1.1.删除src目录，只保留 pom.xom

2.创建子模块（module）

• 2.1 File > New > Module

GroupId: com.sky.cloud
Artifactid: sky-cloud-commons
Version: 1.0-SNAPSHOT

• 2.2 File > New > Module

GroupId: com.sky.cloud
Artifactid: sky-cloud-base
Version: 1.0-SNAPSHOT

3 修改pom文件

• 3.1父模块'sky-cloud-starter-parent'的pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.3.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <packaging>pom</packaging>

    <properties>
        <java.version>1.8</java.version>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <argLine>-Dfile.encoding=UTF-8</argLine>
        <ignite.version>1.7.0</ignite.version>
        <frontend.exists>false</frontend.exists>
        <frontend.build.params></frontend.build.params>
    </properties>

    <groupId>com.sky.cloud</groupId>
    <artifactId>sky-cloud-starter-parent</artifactId>
    <version>1.0-SNAPSHOT</version>
    <modules>
        <module>sky-cloud-commons</module>
        <module>sky-cloud-base</module>
    </modules>

    <!--申明依赖关系-->
    <dependencies>
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>1.1.1</version>
        </dependency>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.17</version>
        </dependency>

    </dependencies>
</project>

• 3.2修改子模块'sky-cloud-commons'的pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <parent>
        <artifactId>sky-cloud-starter-parent</artifactId>
        <groupId>com.sky.cloud</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>

    <artifactId>sky-cloud-commons</artifactId>

    <dependencies>
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
        </dependency>
    </dependencies>

</project>

• 3.3修改子模块'sky-cloud-base'的pom.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <parent>
        <artifactId>sky-cloud-starter-parent</artifactId>
        <groupId>com.sky.cloud</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>sky-cloud-base</artifactId>

    <dependencies>
        <dependency>
            <groupId>com.sky.cloud</groupId>
            <artifactId>sky-cloud-commons</artifactId>
            <version>${project.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka</artifactId>
            <version>1.2.3.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka-server</artifactId>
            <version>1.2.3.RELEASE</version>
        </dependency>
        <dependency>

            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>
</project>

最终目录结构如下：

生成jar包，供后续spring-cloud微服务使用
