eclipse项目属性

Question

我通过IResource设置IProject（IResource.setPersistenceProeprty更具体）的属性。在这种情况下，属性值保存在.metadata文件夹中。这不是很好，因为属性与.project文件断开连接。

如何在.project文件中保存项目属性？

Answer 1

一个常见的解决方案是使用存储在项目（位于＆lt; project＆gt; /。settings 文件夹中）的文件中的project scoped preferences。

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()
