Issue Running Plugin with all 2025.2 EAP Versions

IntelliJ Platform
1

Hi Team,

I’m encountering the following exception when attempting to run my plugin using the latest EAP. The plugin builds successfully, but the issue arises specifically when executing the runIdeLocally task.

The problem seems to be related to this line in the build.gradle file:
version = providers.gradleProperty("ideTargetVersion")

The value provided for ideTargetVersion is:
ideTargetVersion=252.21735.32

runIdeLocally 
intellijPlatformTesting.runIde {
    runIdeLocally {
        version = providers.gradleProperty("ideTargetVersion")
        type = IntelliJPlatformType.IntellijIdeaCommunity
        task {
            jvmArgumentProviders.add({
                [
                        "--add-exports",
                        "java.base/jdk.internal.vm=ALL-UNNAMED"
                ]
            } as CommandLineArgumentProvider)
            systemProperty("ide.native.launcher", "true")
        }
    }
}

possible solution: How to develop against 2025.1 but run against 2025.2? - #5 by jansorg

TLDR: try to disable “Attach coroutine agent” in the host IDE.
