Message 'A resource exists with a different case' is displayed

Symptoms:

• After a project has been imported, the following message is displayed for the specification {CustomImplementation} within the ST-editor: org.eclipse.core.internal.resources.ResourceException: A resource exists with a different case: 'path/file-name.h'. - See error log for details

• The statement {CustomImplementation} is highlighted as faulty.

Cause:

The name of the specified file does not match the requirements/expectations of logi.CAD 3. Most likely, the name is specified with small letters. However, logi.CAD 3 expects capital letters for the POU name that is part of the file name.
Example: For a function named TestVendor01 within the namespace com.oem1.lib1 that is declared after the specification {CustomImplementation}, logi.CAD 3 expects this file name: lcfu___COM.OEM1.LIB1.TESTVENDOR01.h – But if the file name is lcfu___com.oem1.lib1.testvendor01.h, the specification {CustomImplementation} is highlighted as faulty and the above specified message is displayed.

Solution so that the statement is not highlighted as faulty anymore:

1. Correct the name of the specified file so that the POU name is entered in capital letters. See the above example.

2. Make a minimal change within the ST-object with the specification {CustomImplementation} (e.g. insert a blank or an empty line). Then save the SP-object.

Background information: Usually, the specification {CustomImplementation} is only used by a user that creates →vendor blocks.
