无法在 Ubuntu 12.10 中更新 Eclipse Juno

我正在尝试从 Ubuntu 12.10 (amd/x64) 上的 Eclipse Juno (4.2) 获取更新并安装新插件。

我已经尝试了这个论坛上针对以前版本发布的每个解决方案（更改代理设置、更改 Java/jdk 设置、安装 gtk、在 /etc/eclipse.ini 中添加“-Djava.net.preferIPv4Stack=true”... 等等）。

我总是得到以下信息：

'eclipse.buildId=M20120914-1800
java.version=1.7.0_15
java.vendor=Oracle Corporation
BootLoader constants: OS=linux, ARCH=x86_64, WS=gtk, NL=en_US
Command-line arguments:  -os linux -ws gtk -arch x86_64

答案1

嗯，这个问题的答案相当令人惊讶，我无法解释为什么下面的解决方案有效，但事实上它确实有效！

您不需要在配置文件中执行任何操作，也不需要为 eclipse 命令添加任何命令行参数（启动 eclipse 时）。

需要做的就是：将代理设置为手动模式，并为代理仅设置 HTTP 和 HTTPS 值。确保将 SOCKS 代理保留为空。

这帮我解决了这个问题！
