Eclipse: How to add an existing source folder?

Question

ARGH Eclipse is SO frustrating

I have a directory called c:\RemoteSrc . Under this there are 3 directories which are currently source folders (I think? the icon is an open folder with a little orange grid in it) in my Eclipse project. I have dropped a new directory under c:\RemoteSrc which I also want to add to my project.

BUT

If I right click on my project and go "Build Path..." -> "Link Source" and try to add it it tells me "Folder already exists with a different case". Yes i KNOW that the folder already exists THATS WHY IM TRYING TO ADD IT.

Answer 1

A screen capture might help, but if the GUI is un-cooperative, you can:

• close Eclipse
• open the .classpath file which defines your project (it may be located in your workspace)
• see if you can define a new classpathentry of kind "src": this is not the easy method, but that may give you an idea why the GUI refuses to define the same entry.

Answer 2

I think all you need to do is refresh the project. Eclipse does not automatically pick up folders (or files) dropped into it's project directory.

Answer 3

For Linked Sources, you should have something like the following in your .classpath

<classpathentry kind="src" path="module_name"/>

With a corresponding matching entry (within <linkedResources>)in your .project

<link>
  <name>module_name</name>
  <type>2</type>
  <location>path/to/your/module</location>
</link>

NOTE: Removing a linked project doesn't necessarily remove it from the project.
