Spring数据管道Maven配置

我正在尝试使用Spring数据、LingPipe和Mapreduce对文本进行分类。因此，我在本地maven存储库中安装了LingPipe

mvn install:install-file -DgroupId=com.aliasi -DartifactId=lingpipe -Dversion=4.1.0 -Dpackaging=jar -DgeneratePom=true -Dfile=lingpipe-4.1.0.jar

我已经将依赖项添加到我的pom文件中

        <dependency>
            <groupId>com.aliasi</groupId>
            <artifactId>lingpipe</artifactId>
            <version>4.1.0</version>
            <scope>compile</scope>
        </dependency>

---

有没有其他方法可以将第三方Jar添加到Maven中，或者我在这里遗漏了什么？

哼，没有一个响应！！无论如何，我找到了解决办法。它显示classNotFound的原因是我没有将lingpipe jar文件包含到hadoop类路径中。我已经将lingpipe jar导出到hadoop类路径中，并且它按照应该的方式工作。
