我有一个基于插件的RCP应用程序，可以将其导出为产品，直到添加Guava库，它都可以正常工作。我将Guava-23.0库添加到了项目中，并将插件添加到了依赖项中（但是出于某种原因它列出了guava插件为21.0而不是23.0吗？），当我从Eclipse中进行测试时，它运行良好。
但是，当我导出产品然后尝试打开应用程序时，它没有启动，而是创建了这个巨大的错误文件：

我无法终生弄清为什么会发生这种情况或如何解决它。
最佳答案
经过更深入的研究，我找到了解决该问题的方法。这似乎是一种错误，但解决方法是在产品文件的内容标签下手动指定com.google.guava和org.apache.lucene.core的确切版本。
见this answer to the same question on the Eclipse bugzilla
关于java - 将Guava添加到依赖项后，基于插件的RCP产品版本将无法运行，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/47799228/
