Netbeans 8.1 无法通过“打开模块”屏幕

本周，我在全新安装的 ubuntu 18.04 中安装了 netbeans 8.1。在此之前，我已经安装了 jdk、jre 并配置了 JAVA_HOME 变量。尝试打开 netbeans 后，我得到了 netbeans 加载屏幕。然而，当加载屏幕显示“打开模块”时，过一会儿 netbeans 就会关闭。我试过通过终端启动它，但没有出现任何错误。但是，我在 netbeans var 文件夹中找到了这个文本文件

知道为什么会发生这种情况吗？

答案1

我建议大家阅读评论中发布的聊天内容。我无法修复 netbeans 8.1。我所做的是从网站下载最新版本（8.2）并使用 bash 脚本安装它。但是打开 netbeans 8.2 后我无法创建新项目。

然后我发现了以下堆栈溢出问题：https://stackoverflow.com/questions/46476470/cant-create-project-on-netbeans-8-2

总之，我要做的是找到我的 netbeans.conf 文件并更改我的 java_home 路径

答案2

我最近遇到了这个问题，删除缓存文件夹没有帮助。

因此，我通过删除（备份后）文件夹中最近创建的一些模块解决了这个问题$HOME/.netbeans/8.2/modules。
