如何使 Eclipse 插件可部署在多个 Eclipse 版本中？
How to make a Eclipse plug-in deployable in many Eclipse versions?
我为 Eclipse Oxygen 3a 编写了自己的 Eclipse 插件。它在 Eclipse Oxygen 3a 中完美运行。
现在我需要在较新版本的 Eclipse 中部署相同的插件，但是当插件安装在 Eclipse Photon 中时，安装 window 说：
Cannot perform operation. Computing alternate solutions, may take a while: ...
确实拖了半天，结果说我的插件安装不上
如何使该插件适用于多个 Eclipse 版本？

根据要求，这是 Require-Bundle：
Require-Bundle: org.eclipse.ui,
org.eclipse.core.runtime,
org.eclipse.jface.text,
org.eclipse.core.resources,
org.eclipse.ui.editors,
org.eclipse.ui.views;bundle-version="3.8.0",
org.eclipse.ui.ide,
org.eclipse.jdt.ui;bundle-version="3.13.52",
org.eclipse.jdt.core;bundle-version="3.13.50"
没有导入包。

下面可以看到feature.xml文件。我在内部 Apache Web 服务器中部署了一个插件站点，并使用 Eclipse 的“帮助”菜单中的 "Install new software" 选项从 thare 安装。

在feature.xml中只能将自己的插件指定为<plugin ... />，而不是需要的(Eclipse)plug-ins/bundles .
例如，
<plugin

使当前版本的plug-in/bundleorg.eclipse.core.resources（version="0.0.0"是一个占位符，在构建更新站点时将被当前版本替换）的一部分可以被安装。因为org.eclipse.core.resources是一个单例plug-in/bundle（Bundle-SymbolicName: org.eclipse.core.resources; singleton:=true），所以不能和其他版本的plug-in/bundle一起使用。这会阻止您的插件在许多 Eclipse 版本中部署。
