I have a Java project running on Eclipse Galileo, on Windows 7 32-bit. I installed Helios on the same machine and tried to run the existing project but I get the error: 'The project: Builder which is referenced by the classpath, does not exist.. . The project runs fine in Galileo but not in Helios. Now I have a new computer running Windows 7, 64 bit. Installed Eclipse Indigo (64 bit) and copied the existing project files to the same location on new computer. After Eclipse Indigo starts I try to run the project and get the same error.

Do I need to create a new project instead of just manually copying the files? I need help to move existing projects from one version of Eclipse to another. Your assistance is appreciated.

Hi, try to create a new project from existing source code, or import an existing project into workspace.

Open Project->Properties->BuildPath and see if you could find out the exact classpath entry.

Thank you, Nick. I tried creating a new project and then 'Import Projects into Workspace'. I get no errors starting Indigo, but when I try to run any of the configurations i get the error: 'Launching XXXXXX' has encountered a problem. The project: XXXXX which is referenced by the classpath, does not exist.
I checked the Java Build Path and I don't have any entries under the Projects tab.

The message mentions the ClassPath. Could this be a problem in the CLASSPATH User Variable in Windows?

Thank you, Satyam. I checked the Build Path and did not see anything. I have seen other posts where users are having problems when they move a project from one version of Eclipse (Galileo) to a newer one (Helios or Indigo).

In my case, I can run the project in Galileo, but not Helios or Indigo. I need to find out what needs to be different in the newer versions. Any suggestions are welcome. Thank you.

Look at the Launch Config (Run->Run Configurations page). On the Classpath tab for the launch config check to see if it is referencing another project.

By the way, Satyam. About the message...
The project: XXXXX which is referenced by the classpath, does not exist.

Where does the classpath reference the XXXXX project? There is a 'Classpath' tab under 'Run Configurations' can it be there?

Thanks again.

David, Thanks again for your comments. I checked and found a strange entry in the Classpath tab of Run Configurations. Under the 'User Entries' and under 'XXXX (default classpath)' There is a line item that has just an icon but no description next to it. When I compare it to the version that works (in Galileo), the same line item has a different icon with text next to it. I tried to correct it but could not edit or remove that item. I included a screenshot that shows the differences. See file attachments.

I think this may be the source of the error. Can you tell me how to correct it?

Thank you.

I took a look at the screenshot. Is Builder also a Java project? If so, you need to import that project into the same workspace as your current project. The icon without description text is due to Eclipse could not found the project.
