Eclipse The import org.hibernate 无法解析

Question

我对 Android SDK 很陌生。我正在尝试使用 Hibernate/Criteria，但出现错误。

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

我看到Eclipse中已经安装了Hibernate，但是为什么一直显示错误？

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

错误

        // Create a LatLng object for the current location
        LatLng latLng = new LatLng(latitude, longitude);      

        // Show the current location in Google Map        
        googleMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));

        // Zoom in the Google Map
        googleMap.animateCamera(CameraUpdateFactory.zoomTo(20));
        googleMap.addMarker(new MarkerOptions().position(new LatLng(latitude, longitude)).title("You are here!"));
    }

您需要将 Hibernate Jar 添加到项目类路径或 eclipse 库列表中。

此外，通过添加帮助-> 安装新软件，您正在为 eclipse 添加 Hibernate 插件，而不是向您的 eclipse 项目添加 Hibernate 库。

以下是一些用于将 jar 添加到 eclipse 项目或类路径的链接：
