Hbase依赖的guava是12.0，程序中用到的guava是22.0，jar包冲突，总是报NoSuchMethod和ClassNoDef之类的错误

解决方法：

将冲突的一方第三方依赖包所有的依赖打包成一个整体。借用: maven-shade-plugin插件。

建立一个新的maven项目，将guava-22.0单独打成jar包，并改名，再重新放回源程序

1、guava单独打成jar包，并加入源程序的maven本地仓库

（1）、guava单独打成jar包的pom文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>Guava</groupId><artifactId>guava</artifactId><version>1.0</version><dependencies><dependency><groupId>com.google.guava</groupId><artifactId>guava</artifactId><version>22.0</version></dependency>
</dependencies><build><plugins><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-shade-plugin</artifactId><version>3.1.0</version><configuration><createDependencyReducedPom>false</createDependencyReducedPom></configuration><executions><execution><phase>package</phase><goals><goal>shade</goal></goals><configuration><relocations><relocation><pattern>com.google.guava</pattern><shadedPattern>Guava.guava</shadedPattern></relocation><relocation><pattern>com.google.common</pattern><shadedPattern>Guava.common</shadedPattern></relocation></relocations><transformers><transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer" /></transformers></configuration></execution></executions></plugin></plugins></build></project>

（2）打入源程序的maven本地仓库

mvn install:install-file -Dfile=XXX/guava-1.0.jar -DgroupId=Guava -DartifactId=guava -Dversion=1.0 -Dpackaging=jar

2、源程序引入新的guava-22.0jar包

<dependency><groupId>Guava</groupId><artifactId>guava</artifactId><version>1.0</version></dependency>

3、程序中引用新的guava

//import com.google.common.base.Charsets;
//import com.google.common.hash.BloomFilter;
//import com.google.common.hash.Funnel;
//import com.google.common.hash.PrimitiveSink;import Guava.common.hash.BloomFilter;
import Guava.common.hash.Funnels;

注释部分是原来的import
