Why Isn't My Eclipse Code Completion Working?

Eclipse Code Completion Not Functioning

In Eclipse, code completion is an essential tool for enhancing productivity. However, users may encounter instances where code completion ceases to function. If you're experiencing this issue after setting up Eclipse 3.4.2 with plugins, here's a possible solution:

Restoring Default Content Assist Options

Navigate to "Windows > Preferences > Java > Editor > Content Assist > Advanced." Under "Content Assist Proposals," make sure to restore the default options. These should include:

• Other Java Proposals
• SWT Template Proposals
• Template Proposals
• Type Proposals

If you notice duplicate entries, uncheck any that do not end with "(Mylyn)."

Once these defaults are restored, restart Eclipse and try invoking code completion again. By resetting the content assist options, you can potentially resolve the "No Default Proposals" issue and restore code completion functionality.
