GenerateJavaTask breaks Gradle configuration cache in 8.4.1 (regression from #918)

[mrmegapolys]

Description

GenerateJavaTask accesses Task.project at execution time via JacksonVersionDetector.detectVersions(project) in the @TaskAction generate() method. This was introduced in #918 (v8.4.1) and breaks Gradle configuration cache.

Works on 8.3.0, broken on 8.4.1.

How to Reproduce

1. Enable Gradle configuration cache (org.gradle.configuration-cache=true in gradle.properties)
2. Apply the DGS codegen plugin v8.4.1
3. Run ./gradlew generateJava

Error

Task `:generateJava` of type `com.netflix.graphql.dgs.codegen.gradle.GenerateJavaTask`:
invocation of 'Task.project' at execution time is unsupported with the configuration cache.

Root Cause

JacksonVersionDetector.detectVersions(project) resolves project.configurations.findByName("compileClasspath") and iterates resolved artifacts at execution time. The configuration cache requires that Task.project is not accessed during task execution.

This is a regression — the same class of issue was previously fixed in #587.

Environment

• DGS Codegen: 8.3.0 (works) / 8.4.1 (broken)
• Gradle: 9.4.1
• Configuration cache: enabled
