未设置JAVA_HOME

Question

我正在尝试安装opennlp，所以我可以将它用于我的nlp课程项目。我的Windows 8计算机上有eclipse kepler 我读了这么多关于如何安装但没有运气的在线页面我读 http://sharpnlp.codeplex.com/discussions/263620 http://sharpnlp.codeplex.com/discussions/263620 以及该网站不允许我添加的许多其他链接

但他们似乎没有帮助我我所做的是以下内容：

这基本上就是我所做的一切然而我无法在eclipse kepler上使用opennlp 任何建议.. ??

Answer 1

我认为你有很多无关的问题。让我们从顶部开始：

未设置JAVA_HOME

您的JAVA_HOME未设置，您已自行修复。好！但是，我认为如果你想在Eclipse中使用OpenNLP，这并不是绝对必要的。

C:\Users\lina>set JAVA_HOME=C:\Program Files\Java\jdk1.7.0_51

缺少JAR文件

Unable to access表示JAR文件不在那里。文件夹opennlp-tools-1.5.0.jar中没有名为C:\Users\lina>的文件。它很容易修复：将JAR文件放在文件夹中;）

C:\Users\lina>java -jar opennlp-tools-1.5.0.jar
Error: Unable to access jarfile opennlp-tools-1.5.0.jar

构建OpenNLP

然后你尝试构建OpenNLP。我认为构建OpenNLP不是必须使用它。您获取的最后一个错误意味着您正在构建的项目的依赖项缺失。

使用OpenNLP

由于您使用Maven和Eclipse，因此使用OpenNLP应该很容易。在Eclipse上创建一个新的Maven项目，打开pom.xml文件并为OpenNLP添加Maven依赖项（你可以在OpenNLP的网站上找到它）：

<dependency>
  <groupId>org.apache.opennlp</groupId>
  <artifactId>opennlp-tools</artifactId>
  <version>1.5.3</version>
</dependency>

现在Maven将下载OpenNLP并将其放在Eclipse项目的路径上。你可以在事后使用它。

我会选择这个解决方案。
