为什么 IResource.getRawLocation() 为 IProject 返回 null

Why does IResource.getRawLocation() return null for IProject(为什么 IResource.getRawLocation() 为 IProject 返回 null)

问题描述

我需要一个项目文件夹的绝对位置，所以我尝试了

I need the absolute location of a project folder, so I tried

project.getRawLocation()

但这会返回 null (至少在我使用 Import ... Existing projects into workspace 手动导入项目的情况下，我已经检查了 将项目复制到工作区复选框).

but this returns null (at least in my case in which I have imported the project manually using Import ... Existing projects into workspace and I have checked the Copy projects into workspace checkbox).

事情是这样的

project.getParent().getRawLocation() 

返回正确的 /work/Projekte/runtime-MyProduct.product

和

project.members()[0].getRawLocation()

返回 /work/Projekte/runtime-MyProduct.product/Test/.cproject 这也是正确的.

returns /work/Projekte/runtime-MyProduct.product/Test/.cproject which is correct as well.

因此，我希望如此

project.getRawLocation() 

会返回 /work/Projekte/runtime-MyProduct.product/Test，但它会返回 null.

would return /work/Projekte/runtime-MyProduct.product/Test, but it returns null.

谁能解释和/或告诉我哪里错了?

Can anyone explain and/or show me where I'm wrong?

推荐答案

getRawLocation() 说

如果此资源是现有项目，则返回的路径将为等于项目描述中的位置路径.

If this resource is an existing project, the returned path will be equal to the location path in the project description.

以及项目描述的 JavaDoc IProjectDescription.getLocation() 说:

and the JavaDoc for the project description IProjectDescription.getLocation() says:

如果应该使用默认位置，则返回null

null is returned if the default location should be used

getLocation() 调用会返回一个路径.

The getLocation() call will return a path.
