java - eclipse 项目属性

Question

我正在IResource通过. 在这种情况下，属性值保存在文件夹中。这不是很好，因为财产与文件断开了连接。IProjectIResource.setPersistenceProeprty.metadata.project

如何将项目属性保存在.project文件中？

Answer 1

一个常见的解决方案是使用项目范围内的首选项，这些首选项存储在项目内的文件中（在<project>/.settings文件夹中）。

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()
