Maven will rely on third-party packages to package (package) into the jar

Prerequisite : The project is a pure maven java project, created through file-->new-->project-->maven in the idea, not a spring boot project (not through file-->new-->project--> , The spring boot project can pass the default ), no additional operations are required.

1. Encountered a problem, the project is packaged, and there is no third-party package in the jar

Directory Structure

 

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>

    <version>1.0-SNAPSHOT</version>
    <properties>
        <java.version>1.8</java.version>
        <spring-cloud.version>Greenwich.SR1</spring-cloud.version>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

        <!--辅助工具类 maven仓库引入方式-->
        <dependency>
            <groupId>cn.hutool</groupId>
            <artifactId>hutool-all</artifactId>
            <version>4.5.9</version>
        </dependency>

    </dependencies>

</project>

 

 

maven: clean-->compile-->package

No hutool.jar

2. Solve

The guess is that the packaging elements are missing in pom.xml

Add build plugin

<?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"

        </dependency>

    </dependencies>

    <build>

        </plugins>
    </build>
</project>

Execute in maven

Result (depending on the package has been entered, but become a class):

 

 3. Into the jar package

Modify the plugin configuration

C:\Users\Lenovo\.m2\repository\org\apache\maven\plugins\maven-assembly-plugin\2.2-beta-5

 

 

 Open with winzip, and drag the jar-with-dependencies.xml file (press and hold the left mouse button) out, modify the unpack to false

Drag the modified file into the compressed package

Repack

result:
