我有系统：ubuntu-9.04-amd64。我从官方默认存储库安装了 IDE NetBeans 6.5。一切正常。
但现在，我决定使用 ubuntu-9.10-desktop-amd64。
我用：（/和/usr）格式化了我的部分内容。/home和以前一样。我已经正确安装了 ubuntu-9.10，正确（可能）安装了 IDE NetBeans 6.5。
但是现在，我什至无法使用这个 IDE 创建最简单的 java 应用程序。如果我使用 CommandLine 编译 java 类，一切正常（~/javac someclass.java | java）。
如果我启动 IDE (NB 6.5)，则 File->New Project-> This New Project 已创建，但未编译：如果显示 (F6) 错误：
