maven工程jar与平台jar冲突解决办法

1、打包时报错信息如下：

[INFO] --- maven-enforcer-plugin:1.3.1:enforce (enforce-banned-dependencies) @ xc_exam ---
[WARNING] Rule 1: org.apache.maven.plugins.enforcer.RequireUpperBoundDeps failed with message:
Failed while enforcing RequireUpperBoundDeps. The error(s) are [

2、com.zmbsms.os:zmbsms_core:4.1为我们的平台包，平台包中也引用了httpclient、poi-2.5.1-final，但与该工程中的版本不同，处理方式为：

<!-- zmbsms-core -->
<dependency>
			<groupId>com.zmbsms.os</groupId>
			<artifactId>zmbsms_core</artifactId>
			<version>4.1</version>
</dependency>

改为：

<!-- zmbsms-core -->
<dependency>
			<groupId>com.zmbsms.os</groupId>
			<artifactId>zmbsms_core</artifactId>
			<version>4.1</version>
			<exclusions>
			    <exclusion>
				   <groupId>org.apache.httpcomponents</groupId>
			       <artifactId>httpclient</artifactId>
			    </exclusion>
			    <exclusion>
			        <groupId>poi</groupId>
			        <artifactId>poi-2.5.1-final</artifactId>
			    </exclusion>
			</exclusions>
</dependency>
