The Problem

When using new versions of Java (anything higher than 1.8), you may see the following error when attempting to use any of the SDK tools, e.g. sdkmanager...

Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema

Starting with Java 9, the XmlSchema library is not included in the base JDK.

To get around this, many people will resort to downgrading to JDK 1.8. This is unneccesary.

You may need to know the ITC_TEAM_ID, particularly when setting up automatic deployments to TestFlight in your CI/CD pipeline.

One way to do this is to use a Fastlane Spaceship playground.

I assume if you're reading this, you already have Fastlane installed.

To start a playground, run the following command in a terminal session:

fastlane spaceship

1. Remove any references to the submodule in your project
2. Delete the relevant section from the .gitmodules file
3. Stage the .gitmodules changes: git add .gitmodules
4. Delete the submodule reference in .git/config
5. Run git rm --cached path_to_submodule
6. Run rm -rf .git/modules/path_to_submodule
7. Run rm -rf path_to_submodule
8. Finally, git commit -m "Removed submodule "
