主要错误是这个：Unable to find main class

解决办法有两种：

1、在blade-common的pom内加上如下配置

 <build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <skip>true</skip>
                <finalName>${project.name}</finalName>
            </configuration>
        </plugin>
        <plugin>
            <groupId>com.spotify</groupId>
            <artifactId>docker-maven-plugin</artifactId>
            <version>${docker.plugin.version}</version>
            <configuration>
                <skipDockerBuild>true</skipDockerBuild>
            </configuration>
        </plugin>
    </plugins>
</build>

2、在blade-common内随意一个类增加一个空的

 public static void main(String[] args) {
   
}

	<build>
	<plugins>
	<plugin>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-maven-plugin</artifactId>
	<configuration>
	<skip>true</skip>
	<finalName>${project.name}</finalName>
	</configuration>
	</plugin>
	<plugin>
	<groupId>com.spotify</groupId>
	<artifactId>docker-maven-plugin</artifactId>
	<version>${docker.plugin.version}</version>
	<configuration>
	<skipDockerBuild>true</skipDockerBuild>
	</configuration>
	</plugin>
	</plugins>
	</build>
