Liferay 6.1.2 第一次新建工程的时候报错。

阅读更多

第一次创建liferay项目失败：

1 创建liferay项目的时候，控制台报java.util.zip.ZipException: error in opening zip file的错误 ，十分诡异。

方法是：删除liferay-plugins-sdk-6.1.1-20130816114619181\liferay-plugins-sdk-6.1.1\.ivy 下的ivy-2.3.0.jar文件。

然后再创建项目， 项目会重新下载依赖，.ivy下会多一个cache文件。



2 接着继续报错，错误变成eclipse工作空间下的log日志显示：

3 查阅国外网站，找了解决方法：
https://issues.liferay.com/browse/IDE-1282

（1） 调整java complicance  编译环境为 1.6
（2） 调整tomcat下的jdk为1.6



再试，问题解决。
liferay 6.1.2居然只能用1.6的jdk来弄，坑爹呀。
