没有主属性清单：springcloud项目父子工程，子工程jar

在父maven pom中添加

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <fork>true</fork>
                    <addResources>true</addResources>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

重点添加

<executions>
    <execution>
        <goals>
            <goal>repackage</goal>
        </goals>
    </execution>
</executions>
