Openbravo编译失败

Question

我有一个openbravo-3.0MP28.2.tar，正在尝试安装它，当我进入"ant install.source“步骤时，我得到了以下异常：

我做错了什么？我的$CLASSPATH变量是空的，但当我在不同的机器上使用空的全局$CLASSPATH编译openbravo时，它仍然可以正常运行。

这不是平台问题，而可能是某个特定Openbravo配置中的错误。遵循这里描述的步骤

http://wiki.openbravo.com/wiki/How_to_setup_Eclipse_IDE

可以成功安装、配置和使用Openbravo实例(您缺少jar文件)
