spring-boot-maven-plugin多模块install问题解决办法

引用地址https://www.cnblogs.com/geekdc/p/10744903.html

 

一、问题描述：

　　项目分多个模块，open-eureka注册中心、open-provider服务提供者、open-common公共部分，provider依赖common。父pom使用spring-boot-maver-plugin插件，项目直接运行Main主类没问题，但是install报common中的类找不到符号.

二、查找问题：

　　spring-boot-maven-plugin 打包跟普通的apache-maven-plugin打包不一致，前者打的jar 包是可以直接用java -jar  name.jar 来执行的，但是common模块只是作为一个其他模块的依赖来使用，并不需要有启动类，也不需要执行。

三、解决办法：

　3.1、删除父pom中的spring-boot-maven-plugin插件依赖，父pom不需要<build>

parent.pom

　3.2、只在需要独立运行的模块，如provider模块中加载spring-boot-maven-plugin插件依赖  

provider.pom

复制代码
<?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">
    <parent>
        <artifactId>starfast-open</artifactId>
        <groupId>com.starfast.open</groupId>
        <version>0.0.1-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>
    <artifactId>open-provider</artifactId>
    <name>open-provider</name>

    <dependencies>
        <!--common模块-->
        <dependency>
            <groupId>com.starfast.open</groupId>
            <artifactId>open-common</artifactId>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>
复制代码

3.3、删除不需要独立运行的模块中的spring-boot-maven-plugin插件依赖

common.pom

install结果：

顺便吐槽，网上的垃圾文章真多，还好发现了该篇文章，

多谢作者。

ps：实际操作中，我原来项目就是在parent中定义了build，并且在所依赖的本项目中的jar包中使用了build

1.去掉parent中的build

2.去掉所依赖的本项目中的模块pom中的build部分（也解决了不需要发布的jar包，而只是被别的项目依赖的jar包，还需要写main入口程序的无用代码）

3.在需要发布的项目模块中，添加build，并且格式为

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
            </plugin>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <!--fork : 如果没有该项配置devtools不会起作用，即应用不会restart -->
                    <fork>true</fork>
                    <addResources>true</addResources><!--支持静态文件热部署 -->
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-deploy-plugin</artifactId>
                <configuration>
                    <skip>true</skip>
                </configuration>
            </plugin>
        </plugins>
        <resources>
            <resource>
                <directory>src/main/webapp</directory>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
            </resource>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
        </resources>

    </build>

 

4.注意要把资源文件也用build打包
