Eclipse不会构建项目，因为有“构建路径pr0blem"，但是源文件夹确实存在

Question

这种情况越来越频繁地发生在我们身上。我们的项目中有一个源文件夹。eclipse经常会坚持它不能构建项目，即使：

• 文件夹存在，
• 权限允许读/写，
• eclipse实际上在“”视图中显示文件夹！

​

​

工作区日志和控制台中都没有相关的条目。我们对此没有很好的解决方案，通常需要多次执行以下操作：

• 刷新项目
• 关闭/开放项目
• 清洁工程
• 重新启动eclipse (使用-clean)

每次发生都要花20分钟左右。

我的Eclipse是最近的开普勒版本之一(4.3.2)，运行在Ubuntu12.04LTS上。

有什么已知的解决办法吗？我应该为eclipse提交一个bug吗？

Answer 1

到目前为止，最好的解决办法似乎是：

• 从eclipse构建路径对话框中删除有问题的条目，
• 重新开始月蚀
• 封闭工程
• 还原.classpath文件
• 开放式工程
• 清洁自动建造
