`java.import.gradle.user.home` Setting not Respected

Environment

• VS Code Version: 1.99.22418 (Flatpak build)
• Extension Version: vscjava.vscode-java-pack 0.29.0
• JDK Type & Version: Eclipse Temurin 21.0.7+6.0.LTS
• OS Type & Version: GNU/Linux x64 6.12.23-1-lts #1 SMP PREEMPT_DYNAMIC

Step to Reproduce

• Set GRADLE_USER_HOME environment variable within the operating system — GRADLE_USER_HOME="/path/to/user-home/.cache/gradle"
• Set "java.import.gradle.user.home": "/path/to/user-home/.cache/gradle in global settings.json
• Create/Open a Gradle project

Expected Behavior

Gradle processes should use the correct location defined by java.import.gradle.user.home.

Actual Behavior

Gradle processes still default to /path/to/user-home/.gradle

Additional Information

I've also tried to set java.import.gradle.user.home in settings.json at the project level.

Start by reproducing the issue with GRADLE_USER_HOME and java.import.gradle.user.home set as described, then trace how the Java extension pack passes Gradle settings to Gradle processes. Done means Gradle processes use the configured cache location rather than the default .gradle path, including when the setting is defined at project level.
