@steelhead31 OK, I actually spent proper time with Copilot in my IDE and got this to work.

Pull request overview

Updates the linux/ Gradle wrapper to 9.3.0 and adjusts Linux packaging Gradle builds to work under Gradle 9.x (notably around exec usage in task actions and JUnit runtime dependencies for package tests).

Changes:

• Bump Gradle wrapper to 9.3.0 (gradle-wrapper.properties, gradle-wrapper.jar, gradlew, gradlew.bat).
• Update multiple Linux packaging build.gradle files to use a new ExecHelper wrapper for exec calls and add junit-platform-launcher to package test runtime.
• Replace some project.copy {} usages with copy {} in Debian scripts.

• The PR description says the Gradle 9.3 compatibility fix is to use exec {} instead of project.exec {} inside doLast blocks, but this file introduces ExecHelper and calls execHelper.exec {} instead. Consider switching to exec {} directly (or updating the PR description) to avoid confusion and keep the change aligned with the stated approach.

	// Create ExecHelper instance for Gradle 9.x compatible exec operations
	def execHelper = objects.newInstance(ExecHelper)

The indentation in these if blocks is inconsistent (extra indentation on the execHelper.exec blocks and misaligned commandLine arguments), which makes it harder to verify what runs under each condition. Reformatting this section to a consistent indentation level would improve readability and reduce the chance of future brace/closure mistakes.

See below for a potential fix:

			execHelper.exec {
				workingDir "src/main/packaging"
				commandLine "docker", "build", "--no-cache", "--pull",
					"--build-arg", "IMAGE=arm32v7/debian:bullseye",
					"-t", "adoptium-packages-linux-jdk-debian",
					"--build-arg=CONTAINER_REGISTRY=${containerRegistry}",
					"-f", "Dockerfile",
					getProjectDir().absolutePath + "/src/main/packaging"
				}
		}

		if ("$arch" == "riscv64") {
			execHelper.exec {
				workingDir "src/main/packaging"
				commandLine "docker", "build", "--no-cache", "--pull",
					"--build-arg", "IMAGE=riscv64/ubuntu:jammy",
					"-t", "adoptium-packages-linux-jdk-debian",
					"--build-arg=CONTAINER_REGISTRY=${containerRegistry}",
					"-f", "Dockerfile",
					getProjectDir().absolutePath + "/src/main/packaging"
				}
		}

This looks good, I'll use this as a base for bumping gradle in the linux_new / jenkins automation processes also.
