# 86.4 使用Maven创建可执行JAR

`spring-boot-maven-plugin`能够用来创建可执行的'胖'JAR。如果正在使用`spring-boot-starter-parent` POM，你可以简单地声明该插件，然后你的jar将被重新打包：

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

如果没有使用parent POM，你仍旧可以使用该插件。不过，你需要另外添加一个`<executions>`片段：

```markup
<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <version>2.0.0.RELEASE</version>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>
```
