Eclipse The import org.hibernate cannot be resolved

提问by Naveen Gamage

I'm quite new to Android SDK. I'm trying to use Hibernate/Criteria but it gives an error.

我对 Android SDK 很陌生。我正在尝试使用 Hibernate/Criteria，但它给出了一个错误。

I have installed Hibernate following these steps.

我已经按照这些步骤安装了 Hibernate。

Help -> Install New Software
Click on Add. Location: http://download.jboss.org/jbosstools/updates/stable/
Inside JBoss Web and Java EE Development folder, select Hibernate Tools
Click on Next

I can see that Hibernate has been installed in Eclipse but why the error keeps showing?

我可以看到 Eclipse 中已经安装了 Hibernate，但为什么错误一直显示？

import org.hibernate.Criteria;
Criteria criteria = new Criteria();

You need to add Hibernate Jar to your project classpath or to your eclipse library list.

您需要将 Hibernate Jar 添加到您的项目类路径或您的 eclipse 库列表中。

Also, by adding Help-> Install New Software you are adding Hibernate plugin for eclipse and not adding Hibernate lib to your eclipse project.

此外，通过添加 Help-> Install New Software，您将为 eclipse 添加 Hibernate 插件，而不是将 Hibernate lib 添加到您的 eclipse 项目中。

Here are some links for adding jars to eclipse project or classpath:

以下是将 jars 添加到 eclipse 项目或类路径的一些链接：
