How to place a file on classpath in Eclipse?

As this documentation says, "For example if you place this jndi.properties file on your classpath", but how can I place the .properties file on my classpath if I am using Eclipse?

Solution 1:

Just to add. If you right-click on an eclipse project and select Properties, select the Java Build Path link on the left. Then select the Source Tab. You'll see a list of all the java source folders. You can even add your own. By default the {project}/src folder is the classpath folder.

Solution 2:

One option is to place your properties file in the src/ directory of your project. This will copy it to the "classes" (along with your .class files) at build time. I often do this for web projects.

Solution 3:

This might not be the most useful answer, more of an addendum, but the above answer (from greenkode) confused me for all of 10 seconds.

"Add Folder" only lets you see folders that are the sub-folders of the project whose build path you are looking at.

The "Link Source" button in the above image would be called "Add External Folder" in an ideal world.

I had to make a properties file that is to be shared between multiple projects, and by keeping the properties file in an external folder, I am able to have only one, instead of having a copy in each project.
