当我尝试更新时，我收到此错误：

我通过从 ZIP 文件中复制必要的插件创建了 p2 更新站点。

如何强制 p2 更新插件？

【参考方案1】：

发生这种情况是因为 org.eclipse.equinox.simpleconfigurator 包在包清单中标记为“singleton=true”。这不允许 p2 director 安装此捆绑包的多个实例。

你可以更新它：

首先卸载原始包（这并不容易，因为此包是 RCP 功能的一部分），

或（这可能是更实用的解决方案）手动将 p2 存储库中的 1.0.200.v20110815-1438 捆绑包替换为原始 1.0.200.v20110502-1955 捆绑包。由于捆绑包的版本相同（1.0.200），您可能希望内容也相同。
