第一步、我们先去官网下载我们要用的东西
1.Eclipse
2.SDK
3.Tomcat
这是官网下载地址--》https://www.liferay.com/zh/downloads
下面是图片说明
这是Eclipse下载说明
SDK下载图片
Tomcat下载
官网只有最新的Tomcat所以我们去这个下载地址：https://sourceforge.net/projects/lportal/files/Liferay%20Portal/
第二步、在Eclipse上配置Liferay
先配置Tomcat
然后配置sdk
在这一步之后可能会出现两个错误如果没有出现不用理会。
错误一
Invalid SDK settings.Configure app.server.parent.dir property in build.Robbin.properties（这个就是下面新建的文件名） to point to Liferay home
解决方法：
在SDK目录下面新建如下文件 这个文件名字就是上面标红的文件名
文件内容如下里面的路径根据自己的liferay Tomcat的路径修改

错误二

解决方法：

to
C:\Users\Robbin\.liferay\mirrors\cdn.repository.liferay.com\nexus\content\repositories\liferay-snapshots-ce\com\liferay\org.apache.ivy\2.4.0.LIFERAY-PATCHED-1-SNAPSHOT\org.apache.ivy-2.4.0.LIFERAY-PATCHED-1-SNAPSHOT.jar
上面标红的是报错信息意思就是说从上面的地址下载org.apache.ivy-2.4.0.LIFERAY-PATCHED-1-SNAPSHOT.jar 然后放到下面的地址去。
我们试着用上面的地址发现根本打不开，然后我们又来试
http://cdn.repository.liferay.com/nexus/content/repositories/liferay-snapshots-ce/com/liferay/org.apache.ivy/2.4.0.LIFERAY-PATCHED-1-SNAPSHOT/org.apache.ivy-2.4.0.LIFERAY-PATCHED-1-SNAPSHOT.jar
这个地址也打不开。
我们就直接使用https://repository.liferay.com这个地址 搜索内容 org.apache.ivy
这是百度网盘地址：org.apache.ivy-2.4.0.LIFERAY-PATCHED-1-SNAPSHOT.jar--->链接:http://pan.baidu.com/s/1nvjQeCD 密码: nekb
如果没有配置MAVEN，可以按照下图方式进行下载
下载下载放到提示的目录就可以了，我的目录是：
C:\Users\Robbin\.liferay\mirrors\cdn.repository.liferay.com\nexus\content\repositories\liferay-snapshots-ce\com\liferay\org.apache.ivy\2.4.0.LIFERAY-PATCHED-1-SNAPSHOT\org.apache.ivy-2.4.0.LIFERAY-PATCHED-1-SNAPSHOT.jar
然后再次上面配置SDK的步骤，会弹出一个框要等很长时间。
如果还是报错或者很慢就使用下面的方法。
在SDK目录下新建.ivy如果有了就不建了。
在.ivy里面放【ivy-2.4.0.LIFERAY-PATCHED-1-SNAPSHOT.jar】和 cache
ivy-2.4.0.LIFERAY-PATCHED-1-SNAPSHOT.jar是我们刚才下载的。
cache 这个文件它会自动生成。这是百度网盘下载地址---》链接: http://pan.baidu.com/s/1qY71DFm 密码: djt3
接下来就是成功的图片了
结束：第二个错误还行网上有解决方法，第一个错误我在网上找了一圈好象没有人遇到，所以解决起来有点费时所以在这儿记录一下。
