Intellij+maven：jar包冲突的解决方法(Hbase和Guava的冲突)

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">

            <plugin>
                <groupId>org.apache.maven.pluginsgroupId>
                <artifactId>maven-shade-pluginartifactId>
                <version>3.1.0version>
                <configuration>
                    <createDependencyReducedPom>falsecreateDependencyReducedPom>
                configuration>
                <executions>
                    <execution>

                        <goals>
                            <goal>shadegoal>
                        goals>
                        <configuration>
                            <relocations>
                                <relocation>

                                    <shadedPattern>Guava.guavashadedPattern>
                                relocation>
                                <relocation>
                                    <pattern>com.google.commonpattern>
                                    <shadedPattern>Guava.commonshadedPattern>
                                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>GuavagroupId>
      <artifactId>guavaartifactId>
      <version>1.0version>
    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
