spring boot maven plugin Executa

spring-boot-starter-parent 包含了repackage goal，所以就不需要在pom.xml里面配置如下复杂的goal目标了：

<build>
  ...
  <plugins>
    ...
    <plugin>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-maven-plugin</artifactId>
      <version>2.1.3.RELEASE</version>
      <executions>
        <execution>
          <goals>
            <goal>repackage</goal>
          </goals>
        </execution>
      </executions>
    </plugin>
    ...
  </plugins>
  ...
</build>

因此，只需要简单地配置：

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

就能打成Executable Jar
