Recently, I was in charge of a pure maven project (project requirements should be as light as possible), and I need to complete the packaging work by myself.
Therefore, based on Maven compiler plugin and Maven shade plugin, the project packaging is completed.

Among them:

• Maven compiler plugin is responsible for project compilation;
• maven-shade-plugin is responsible for the final packaging operation.

The following operations are performed in pom.xml file.

Project basic properties

    <groupId>com.test</groupId>
    <artifactId>app</artifactId> //
    <version>0.1.0</version>
    <packaging>jar</packaging>
    
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
    </properties>

Add plug-ins

        <plugins>

            <!-- Compile java project-->

            </plugin>
