Spring Boot creates a non-executable jar package instance tutorial, springjar

We often use this scenario. We only need to pack Spring Boot into a common jar package, which does not contain configuration files for other program applications.

This article describes how to use Maven to compress a Spring Boot application into a normal non-executable jar package.

Configure maven-jar-plugin

<build>  <plugins>    <plugin>      <groupId>org.springframework.boot</groupId>      <artifactId>spring-boot-maven-plugin</artifactId>      <configuration>        <classifier>exec</classifier>      </configuration>    </plugin>    <plugin>      <artifactId>maven-jar-plugin</artifactId>      <executions>        <execution>          <id>exec</id>          <phase>package</phase>          <goals>            <goal>jar</goal>          </goals>          <configuration>            <classifier>exec</classifier>          </configuration>        </execution>        <execution>          <phase>package</phase>          <goals>            <goal>jar</goal>          </goals>          <configuration>            <!-- Need this to ensure application.yml is excluded -->            <forceCreation>true</forceCreation>            <excludes>              <exclude>application.yml</exclude>            </excludes>          </configuration>        </execution>      </executions>    </plugin>  </plugins></build>
