How to adjust the position of items in the Package Explorer in Eclipse?

Issue

Currently, my "Package Explorer" in Eclipse shows as follows:

I want to move the "src" folder to the top of "JRE System Library".

How should I do to achieve it?

Solution

The order of the displayed elements is given by the order of the elements in the .classpath file.

To move the source folder src to the top, open the .classpath file (which is only visible in the Navigator view) and move the following line up so that it is the first child element of the <classpath> element:

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