maven bulid怎么会出现BOOT-INF

1.现象：通过maven install达成jar，目录中出现BOOT-INF
2.独立项目解决：
  <build>
<plugins>
<plugin> 
            <groupId>org.springframework.boot</groupId> 
            <artifactId>spring-boot-maven-plugin</artifactId> 
           <configuration> 
                <classifier>exec</classifier> 
            </configuration> 
        </plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
</build>
3.有依赖关系（多个module）解决
  除了pom.xml文件中增加第二步骤之外，还需在对应的parent的pom中，加入如下代码
  <plugin> 
            <groupId>org.springframework.boot</groupId> 
            <artifactId>spring-boot-maven-plugin</artifactId> 
             <configuration> 
                <source>${java.version}</source> 
                <target>${java.version}</target> 
            </configuration> 
            <executions> 
                <execution> 
                    <goals> 
                        <goal>repackage</goal> 
                    </goals> 
                </execution> 
            </executions> 
        </plugin>
