I am developing a collection of plugins on Eclipse 3.4 (official) on both mac and a PC.

At present (I'm aware it is not the best practice) some of my common plugins export all of their packages.

The problem is this: many of the listed packages are empty because subpackages are not, for example: prefix.core may be empty while prefix.core.model may not be.

Even though I use the same manifest file, having the empty packages listed on one platform raises an error in the manifest file on the other platform. If I omit the packages in that platform, then when I come to the other platform I'm told that the plugin does not export everything.

Any idea what is going on? I have no idea why there would be differences between the PC and the Mac on a non-UI related issue. The only significant difference is that the mac is running Java 5 (still not Eclipse for Java 6) while the PC is running Java 6, but the manifests should have nothing to do with it.

如果您要跨多台机器和平台开发插件，那么使用相同版本的 JVM 通常是一个好习惯。

如果您要在 PC 上构建插件并希望它们在 Mac 上运行，您应该在 Java 5 上进行标准化。您可以通过转到 Window->Preferences->Installed JREs 轻松安装和添加额外的 JRE 到 Eclipse。如果您不希望 PC Java 编码的其余部分使用 5，您甚至可以配置每个项目和启动配置使用的 JRE。

如果这也解决了您的清单问题，我不会感到惊讶。

问题可能是插件开发首选项中设置的错误/警告级别。可能是您在两台机器上都有不同的设置，这会产生问题。

在 Preferences -> Plug-in Development -> Compilers 下，有几个关于不同问题的错误和警告级别的选项，例如对不存在的资源的引用。您可能会发现有什么不同吗？
