java开发需要调用apache phoenix接口，配置pom.xml文件，内容如下：

<repositories>
        <repository>
            <id>apache release</id>
            <url>https://repository.apache.org/content/repositories/releases/</url>
        </repository>
    </repositories>
    
    <dependencies>
        <dependency>
            <groupId>org.apache.phoenix</groupId>
            <artifactId>phoenix-core</artifactId>
            <version>4.5.2-HBase-1.0</version>
        </dependency>
    </dependencies>

下载完成之后，出现错误：

解决方法：

因为依赖冲突，要下载的包在本地m2文件里已经存在，所以将本地资源删除，重新update即可。

从错误报告中可以看到，主要冲突的包有三个：

org.apache.hadoop:hadoop-common:jar:2.5.1

org.iq80.snappy:snappy:jar:0.3

net.sourceforge.findbugs:annotations:jar:1.3.2
