Question

我是Liferay / java / Eclipse的新手。

我正在尝试设置一个简单的Liferay插件项目，但每当我尝试创建项目并单击Finish时，我都会收到错误消息：

“创建Liferay插件项目时出错。”

以下是我正在使用的配置：

Eclipse的开普勒

Liferay Plugins SDK 6.2

Liferay Portal / Tomcat 6.2

java版本：1.8.0_05

环境变量设置为：

$ JAVA_HOME = C：\ Program Files \ Java \ jdk1.8.0_05 $ PATH = / c / Program 文件/爪哇/ jre8 / bin中

以下是错误日志中的堆栈跟踪：

eclipse.buildId=4.3.2.M20140221-1700
java.version=1.8.0_05
java.vendor=Oracle Corporation
BootLoader constants: OS=win32, ARCH=x86_64, WS=win32, NL=en_US

关于导致这种情况的任何想法？

Answer 1

通过删除jre8并使用jre7来修复问题。

Answer 2

我刚从其他地方读到有关编译器的事情。这也可能是一个原因。好吧，我确实将我的改为1.6，它的效果非常好所以你去：

Windows - ＆gt;首选项＆GT; Java的＆GT;编译

在那里你可以改变它
