通过maven引入tika的几个组件：

<dependency>
        <groupId>org.apache.tika</groupId>
        <artifactId>tika-core</artifactId>
        <version>1.21</version>
    </dependency>
    
    <dependency>
            <groupId>org.apache.tika</groupId>
            <artifactId>tika-parsers</artifactId>
            <version>1.21</version>
        </dependency>  

项目编译后，eclipse的“marker”页，pom文件报错

ArtifactTransferException: Failure to transfer com.googlecode.juniversalchardet:juniversalchardet:jar:1.0.3 from http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced.

解决办法：

从网上下载了这两个jar包，放到“.m2”相应的目录下面，就可以了。

也可以下载tika-bundle-1.21.jar， 解开后，可以得到所有的依赖包。
