强制Eclipse（Helios）在应用程序运行时使用SWT的较新版本 [英] Force Eclipse (Helios) to use a newer version of SWT at application runtime
问题描述
我正在使用Eclipse-Helios开发RCP项目。
I'm developing an RCP project using Eclipse-Helios.
已安装的SWT版本（在plugins目录中）为[org.eclipse.swt -win32-3.6.2，& org.eclipse.swt.jar]
The version of SWT that is installed (in the plugins directory) is [org.eclipse.swt-win32-3.6.2, & org.eclipse.swt.jar]
我需要新的API功能，该功能仅在swt-3.8中可用。 （特别是，我希望在打开之前为SWT颜色对话框设置自定义颜色。）
I require new API functionality that is only available from swt-3.8. (specifically, I wish to set the custom colours, for an SWT color dialog before opening.)
我已经从SWT / Eclipse下载站点下载了3.8.1 [ a href = http://download.eclipse.org/eclipse/downloads/drops/R-3.8-201206081200/#SWT rel = nofollow> http://download.eclipse.org/eclipse/downloads/drops /R-3.8-201206081200/#SWT ]
I have downloaded 3.8.1 from the SWT/Eclipse downloads site [ http://download.eclipse.org/eclipse/downloads/drops/R-3.8-201206081200/#SWT ]
- SWT下载不是一个插件（几个jar，src。 zip和一些自述文件），所以我无法将其添加到目标平台（即使在位置中添加了包含目录之后，它也没有显示为可用的jar）
- 我找不到SWT的更新站点（或任何我可以获得较新版本插件的站点）
如果我将swt.3.8.jar添加到我的类路径中（然后在项目构建路径中增加它的顺序优先级），则可以从我的代码访问新的api功能（并查看源代码）。
但是，当我运行应用程序时，似乎运行时仍在使用旧的SWT jar，因为在尝试访问更新的功能时遇到未知的方法错误。
If I add the swt.3.8.jar to my classpath (and then increase it's order-priority in the project build-path), I am able to access the newer api functionality from my code (as well as view the source). When I run the application however, it seems as though the runtime is still using the older SWT jar, as i get an unknown method error, when attempting to access the newer functionality.
问题：
- 是否有一个SWT存储库位置，可用于使用Eclipse下载SWT的较新版本安装管理器？
- 如果没有，是否可以强制我运行时忽略旧版本（我假设通过plugin.xml）？
- 是否有更好的方法来实现我要执行的操作？
- 当前在helios插件目录中的两个SWT jar之间有什么区别（因为3.8下载仅包含win -32版本）？
- Is there an SWT repository location that I can use to download a newer version of SWT using the eclipse install manager?
- If not, is there a way I can force the runtime to ignore the older version (I assume via plugin.xml)?
- Is there a better way to achieve what I am trying to do?
- What is the difference between the two SWT jars currently in the helios plugins directory (as the 3.8 download only contains the win-32 version)?
预先感谢。
推荐答案
SWT可作为单独的插件在此处下载：
http://download.eclipse.org/eclip se / downloads / drops / R-3.8-201206081200 /＃SWT
SWT is downloadable as a separate plugin here:
http://download.eclipse.org/eclipse/downloads/drops/R-3.8-201206081200/#SWT
Eclipse 3.8包含常规插件，包括SWT（特定于Win32以及通用 org.eclipse.swt_.jar）。我当前使用的是3.8版本，它们作为插件出现。
Eclipse 3.8 contains regular plugins including the SWT (the win32 specific as well as the generic "org.eclipse.swt_.jar"). I am currently using the 3.8 version and they appear as plugins.
我也有Eclipse 3.6（Helios），并且可以使用文件- >导入->插件开发->插件和片段向导。我只是指定了eclipse 3.8目录，并且可以将它们导入我的工作区中。一旦导入，我当然可以将它们包含在运行时环境中。 Eclipse应该自动使用最新版本。
I also have Eclipse 3.6 (Helios) and I was able to import the swt plugins using the "File->Import->Plug-in Development->Plug-ins and Fragments" wizard. I just specified the eclipse 3.8 directory and could import them in my workspace. Once imported I can of-course use them to be included in the runtime environment. Eclipse should use the latest version automatically.
