Greetings,

In my attempt to upgrade to Eclipse IDE for PHP Developers 4.26.0.20221201-1200, I encountered the following error message:

"Cannot complete the install because one or more required items could not be found. Software being installed: Eclipse IDE for PHP Developers 4.26.0.20221201-1200 (epp.package.php 4.26.0.20221201-1200) Missing requirement: Eclipse IDE for PHP Developers 4.26.0.20221201-1200 (epp.package.php 4.26.0.20221201-1200) requires 'org.eclipse.equinox.p2.iu; org.eclipse.platform.feature.group [4.26.0.v20221123-2302,4.26.0.v20221123-2302]' but it could not be found."

I attempted to add download.oracle.com/otn_software/oepe/library/eclipse-oxygen.2 to the Available Software Sites, but this measure proved ineffective.

I would greatly appreciate any assistance you can provide on this matter.

The error message indicates that the Eclipse IDE for PHP Developers installer is unable to find a required dependency, specifically the 'org.eclipse.equinox.p2.iu; org.eclipse.platform.feature.group [4.26.0.v20221123-2302,4.26.0.v20221123-2302]' feature group. This suggests that there may be an issue with the available software sites or with the integrity of the Eclipse IDE for PHP Developers installation package.

Here are some troubleshooting steps you can try to resolve the issue:

Verify the Available Software Sites: Ensure that the Eclipse IDE for PHP Developers installer is using the correct software repositories. Check the Available Software Sites list for any errors or missing URLs.

Clear the Eclipse Cache: Sometimes, cached data can cause conflicts or prevent updates from being installed properly. Try clearing the Eclipse cache by deleting the contents of the following directories:

<workspace_directory>/.metadata/.plugins/org.eclipse.epp.mpc.core/cache
<workspace_directory>/.metadata/.plugins/org.eclipse.equinox.p2.core/cache
Download and Install the Missing Dependency: If the required dependency is available separately, try downloading and installing it manually. You can find the required feature group from the Eclipse website or from a trusted third-party repository.

Reinstall Eclipse IDE for PHP Developers: If the issue persists, consider reinstalling the Eclipse IDE for PHP Developers completely. This will ensure that you have a clean installation with all the necessary dependencies.

Seek Community Support: If you've tried all of the above steps and are still encountering the error, consider seeking help from the Eclipse community forums or from Eclipse support channels. They may be able to provide more specific guidance or identify underlying issues with your installation.
