Could not find a valid gem ...libxml-ruby-2.9.0.gem

[palmoff]

Could not build packaged version under macOS 10.14 Mojave.

Getting two errors:
xcode-select: error: invalid developer directory '/Applications/Xcode-7.3.1.app'
(looks like linked to previous version of Xcode)

ERROR: Could not find a valid gem '/Users/username/packaged-fastlane-master/patches/libxml-ruby-2.9.0.gem' (>= 0) in any repository

Could you please help ?
Any ideas ?

Hello,
It seems like you are having trouble building a packaged version on mac OS 10.14 Mojave due to issues with Xcode and gem dependencies. To fix the Xcode related error, update the xcode path using sudo xcode-select -s /Applications/Xcode.app to point to your current xcode version. For the gem dependency error ADP Vantage HCM try reinstalling the gem with gem install libxml ruby to ensure it's correctly installed and up to date. After addressing these issues, attempt to build your packaged version again. Make sure all necessary dependencies are properly configured for your mac OS environment to avoid further complications.
