如何使Eclipse插件可在许多Eclipse版本中部署？

Question

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，但是例如在Eclipse Photon中安装插件时，安装窗口会显示：

Cannot perform operation. Computing alternate solutions, may take a while: ...

确实需要很长时间，最后说我的插件将不会安装。

如何使此插件可用于多个Eclipse版本？

按照要求，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。

feature.xml文件可以在下面看到。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“安装新软件”选项从thare安装。

Answer 1

在feature.xml中，仅将您自己的插件指定为<plugin ... />，而不是所需的（Eclipse）插件/捆绑包。

例如，

    <plugin
         id="org.eclipse.core.resources"
         download-size="0"
         install-size="0"
         version="0.0.0"
         unpack="false"/>

使当前版本的插件/捆绑包org.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）是可以安装的东西的一部分。由于org.eclipse.core.resources是单件插件/捆绑包（Bundle-SymbolicName: org.eclipse.core.resources; singleton:=true），因此无法与其他版本的插件/捆绑包一起使用。这会阻止您的插件在许多Eclipse版本中进行部署。
