Gradle build scan fails when there is a plugin whose code source does not have a location URL

[nikita-tkachenko-datadog]

Current Behavior

If a Gradle build has a plugin whose classes' CodeSource returns null location, then the following exception is thrown when running build scan:

Gradle version: 8.6

Expected Behavior

The build scan should not assume that every plugin class has a code source whose location is non-null.

Context (optional)

No response

Steps to Reproduce

When running a Gradle build with the Datadog Java tracer attached, the tracer dynamically registers a plugin.
This plugin's classes have a code source that has no location specified.

wget -O dd-java-agent.jar 'https://dtdg.co/latest-java-tracer'
./gradlew --scan cleanTest test -Dorg.gradle.jvmargs=\
-javaagent:dd-java-agent.jar=\
dd.civisibility.enabled=true,\
dd.env=ci,\
dd.service=dummy

Gradle version

8.6
