斯坦福大學NLP RuntimeIOException

我想用Java中的斯坦福NLP做一些情感分析。我正在使用Maven，但出現以下錯誤：斯坦福大學NLP RuntimeIOException

我不確定該怎麼做。我已經從here下載了Stanford CoreNLP，但我不確定我應該在哪裏提取它。

我還添加了

<dependency> 
    <groupId>edu.stanford.nlp</groupId> 
    <artifactId>stanford-corenlp</artifactId> 
    <version>3.5.0</version> 
</dependency> 
<dependency> 
    <groupId>edu.stanford.nlp</groupId> 
    <artifactId>stanford-corenlp</artifactId> 
    <version>3.5.0</version> 
    <classifier>models</classifier> 
</dependency>

我pom.xml文件，並開始運行mvn package時下載，但似乎並沒有幫助。

提取罐子到你的項目文件夾。像projectPath/lib – Nuwanda

當你正在使用Hadoop，您可以通過使用Maven Shade Plugin

用java脂肪罐子項目的建設項目（MVN包），它會創建一個單獨的jar具有所有依賴性合併成it.You需要經過把你的hadoop驅動類作爲mainClass在這裏就像

<transformer> implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer"> 
<mainClass>your-driver-class</mainClass> 
</transformer>
