原文 2019-03-09 08:35:30 1 1 java/ eclipse/ eclipse-plugin

I have a brand new installation of the 2018‑12 R "Eclipse IDE for Enterprise Java Developers", and am attempting to go through an Eclipse Plugin development tutorial (eg. https://www.vogella.com/tutorials/EclipsePlugin/article.html ) While I can create a plugin project, I'm immediately confronted with: 我安装了全新的2018-12 R“面向企业Java开发人员的Eclipse IDE”，并尝试阅读Eclipse插件开发教程（例如https://www.vogella.com/tutorials/EclipsePlugin/article .html ），尽管我可以创建一个插件项目，但我立即遇到了：

NullPointerException at org.eclipse.pde.internal.core.plugin.WorkspaceExtensionsModel.getInstallLocation(WorkspaceExtensionsModel.java:79) on every view change 每次视图更改时，org.eclipse.pde.internal.core.plugin.WorkspaceExtensionsModel.getInstallLocation（WorkspaceExtensionsModel.java:79）处的NullPointerException
Unresolved imports for everything org.eclipse (and javax.inject) (source file) org.eclipse（和javax.inject）所有内容的未解决的导入（源文件）
Unknown extension point (plugin.xml) 未知扩展点（plugin.xml）
Unresolved bundle for every single entry (MANIFEST.MF) 每个条目的未解决的捆绑包（MANIFEST.MF）

I find it hard to believe that Eclipse plugin development is in such a sorry state, so I must be missing some feature. 我很难相信Eclipse插件的开发处于令人遗憾的状态，因此我必须缺少一些功能。 What do I need to look for? 我需要寻找什么？

The Eclipse IDE for Enterprise Java Developers is not for plug-in development . 用于企业Java 开发人员的Eclipse IDE 不适用于插件开发 。

Use one of the following IDE packages instead: 请使用以下IDE软件包之一：

the Eclipse IDE for Eclipse Committers or 用于Eclipse Committer的Eclipse IDE或
the Eclipse IDE for RCP and RAP Developers . 用于RCP和RAP开发人员的Eclipse IDE 。

If a bundle cannot be resolved in MANIFEST.MF , it is missing in the target platform (see Window > Preferences: Plug-in Development > Target Platform ). 如果在MANIFEST.MF无法解析包，则目标平台中将丢失该捆绑包（请参阅窗口>首选项：插件开发>目标平台 ）。 And bundles missing in the target platform cause unresolved imports and unknown extension points. 目标平台中缺少的捆绑包会导致无法解决的导入和未知的扩展点。
