eclipse项目属性

Question

我通过IResource.setPersistenceProeprty设置IResource（IProject更具体）的属性。在这种情况下，属性值保存在.metadata文件夹中。这不如财产与.project文件断开连接好。

如何在.project文件中保存项目属性？

Answer 1

常见的解决方案是使用project scoped preferences被存储在位于项目中的文件（在<项目> /.settings文件夹）。

ProjectScope ps = new ProjectScope(projectResource); 
IEclipsePreferences prefs = ps.getNode("my.plugin.id"); 
prefs.put("key", "value"); 
prefs.flush(); 

Answer 2

eclipse .project内容通过IProjectDescription接口公开。

IProjectDescription description = IProject.getDescription()
