What's Wrong?

The proxy used in Claude Code Web disallows downloads from plugins-artifacts.gradle.org - this is the host from which plugins published to the Gradle Plugin Portal are downloaded.

As CCW discovered itself:

The issue is clear: plugins-artifacts.gradle.org (Gradle's CDN) is blocked by the proxy.

This prevents any Gradle builds that use non-Gradle-builtin plugins (which is most of them) from working in CCW.

What Should Happen?

Gradle builds using published plugins should be able to resolve them to execute build logic when running in CCW.
