Short Answer 
To resolve the ‘parent.relativepath’ error in Maven, first verify the existence of the parent POM file in the specified directory. Then, check that the relative path in the child POM correctly points to the parent POM, and if it’s missing, locate it in your repositories or download it online while ensuring version compatibility.
Step 1: Verify Parent POM Presence
Begin by confirming that the parent POM file exists in the location specified within your project structure. This step is crucial because if the parent POM is missing, Maven will not be able to find it, leading to the ‘parent.relativepath’ error. Check the designated directory to ensure the file is indeed present.
Step 2: Check Relative Path Accuracy
Next, inspect the relative path defined in the child POM file. This path should accurately reflect the position of the parent POM relative to the location of the child POM. Ensure that you follow these guidelines:
- The path should be precise and account for directory levels.
- Use correct naming conventions, including case sensitivity.
- Adjust any discrepancies if the structure of your project has changed.
Step 3: Locate or Download Missing Parent POM
If you find that the parent POM file is indeed missing, you have two options to resolve the issue. First, try to locate the file within your project or other repositories you may have access to. Alternatively, if it’s not available locally, you can download it from the appropriate repository online. Ensure to verify its version compatibility with your project.
