Eclipse: The resource is not on the build path of a Java project

Question

I have been given a Source Folder (src) of a Java Project. I have created a .project file, kept it inside that folder and imported that Project int

Answer 1

In my case the source folder wasn't specified correctly. To solve the problem :

• Right click on project name in project explorer
• Select Properties
• Select Java Build Path
• Select Source tab and inspect what is there. Make sure to Add Folder... and select the folder which is the root of your source files.

As a result, you will notice that your folder structure in the project explorer will be modified to display package icons and package names instead.
