2.4.0 Configuration takes 25s vs 2s with 2.1.0

[jonathanlermitage]

What happened?

Disable gradle caching, then run gradlew clean buildPlugin test --scan:

• with platform plugin 2.4.0, the configuration phase takes 26 sec: https://scans.gradle.com/s/ffgutmwpb7krc
• with platform plugin 2.1.0, the configuration phase takes 4 sec: https://scans.gradle.com/s/ouijrsmhaq7bc

My unit test contains only one simple test case (assertTrue(true);).
If I do not run the tests (gradlew clean buildPlugin --scan), the performance of the configuration phase is good.
Also, I did not have this problem with the first 2.3.1-SNAPSHOTs. We had a discussion about #1836 on Discourse (Feb 28, via a private discussion), then I tested a 2.3.1-SNAPSHOT build. So, I guess I'm impacted by a recent change.

intellijPlatform {
            create("IC", "2024.3.5")
            instrumentationTools() // commented out when using platform plugin 2.4.0
            pluginVerifier()
            testFramework(TestFrameworkType.Platform)
            zipSigner()
        }

withType<Test> {
        dependsOn("prepareSandbox")
        useJUnitPlatform()

        jvmArgs("-Djava.awt.headless=true")

        testLogging {
            exceptionFormat = TestExceptionFormat.FULL
            events.add(TestLogEvent.PASSED)
            events.add(TestLogEvent.FAILED)
            events.add(TestLogEvent.SKIPPED)
            showStandardStreams = true
            showCauses = true
            showExceptions = true
            showStackTraces = true
        }
    }

I did not reproduce with the intellij template plugin.
I can send my project via https://uploads.jetbrains.com/ if needed.

Relevant log output or stack trace

Steps to reproduce

Disable gradle caching, then run gradlew clean buildPlugin test --scan

Gradle IntelliJ Plugin version

2.4.0

Gradle version

8.13

Operating System

Windows

Link to build, i.e. failing GitHub Action job

No response

Same here. I don't have any performance problems on macOS but on Windows, anything after 2.1 adds 30 seconds to my Gradle import in the IDE which is very annoying.

In the profiler I see that most of the time is spent creating nio file systems on ZIP files. This is extremely slow on Windows compared to macOS and Linux, so maybe you should cache that somehow.

[jonathanlermitage]

Good catch! I tested the intellij template plugin on Linux, not on Windows.

Thanks for the input!
Yes, Windows performance is terrible. IntelliJ Platform Gradle Plugin unit tests are also affected on CI and take two times more time than on other OSes.
