导致错误原因

打包服务引用了guava-retrying:jar:2.0.0，这个jar包又依赖于com.google.guava:guava:jar:22.0-SNAPSHOT，私服库找不到这个依赖，所以导致错误。但是错误不是在私服库中，而是在pom.xml配置文件中。

错误配置

	<dependency>
			<groupId>com.github.rholder</groupId>
			<artifactId>guava-retrying</artifactId>
			<version>2.0.0</version>
		</dependency>

修改为正确配置

<dependency>
			<groupId>com.github.rholder</groupId>
			<artifactId>guava-retrying</artifactId>
			<exclusions>
				<exclusion>
					<groupId>com.google.guava</groupId>
					<artifactId>guava</artifactId>
				</exclusion>
			</exclusions>
			<version>2.0.0</version>
		</dependency>

最后测试，打包成功。
