Question

我正在尝试使用Eclipse RCP为多个系统构建产品（linux gtk / x86，macosx cocoa / x86_64，win32 win32 / x86），但是在专门导出到macosx时我一直在获取NullPointerException。我正在运行Linux，而linux和win32构建导出很好，没有问题。

我正在运行Eclipse 3.6.2（Helios）并为项目安装了所有必需的库（运行正常）。同样，我可以在OSX下运行它。我还安装了必要的delta来启用多平台RCP导出。

以下是导出的错误日志。请注意，在导出错误输出后，.metadata / .plugins / org.eclipse.pde.core /下的临时目录不存在。

非常感谢任何帮助。我在这上面杀了一整天，无处可去，而且我的优秀谷歌技能并没有带回任何东西。

前一段时间我遇到了同样的问题，我想通过删除品牌形象（Bug 292327）解决了这个问题。这个错误在前一段时间（2009年）得到了解决，但它可能是从...开始的一个点。

导出macosx的.product会导致NullPointerException
