"Could not find installation home path." running tests against an EAP snapshot

[rhdunn]

What happened?

Given:

allprojects {
    dependencies {
        intellijPlatform {
            create("IC", "2025.1") {
                useInstaller = true
            }
            testFramework(TestFrameworkType.Platform)
        }
    }
}

I can run the tests in my plugin without issues. However, when using an EAP snapshot I get the error:

• Could not find installation home path. Please make sure product-info.json is present in the installation directory.

I suspect that this is due to the useInstaller = false, but that is necessary as the EAP snapshot builds are not packaged with the full installer setup (e.g. with a JetBrains Runtime) like the release builds are.

Relevant log output or stack trace

java.lang.RuntimeException: Could not find installation home path. Please make sure product-info.json is present in the installation directory.

Steps to reproduce

allprojects {
    dependencies {
        intellijPlatform {
            create("IC", "LATEST-EAP-SNAPSHOT") {
                useInstaller = false
            }
            jetbrainsRuntime()
            testFramework(TestFrameworkType.Platform)
        }
    }
}

Thanks for reporting. When running tests, the IntelliJ Platform test platform tries to resolve the IDE location by locating the com.intellij.openapi.application.PathManager class.
Apparently, in your case, it's not loaded from the IDE's libraries directly but:

C:\Users\user\IdeaProjects\xquery-intellij-plugin\build\idea-sandbox\IC-2025.2\plugins-test\xquery-intellij-plugin\lib\util-252.23892.360-EAP-SNAPSHOT.jar

By some reason, you have the util jar leaked into the runtimeClasspath and the prepareTestSandbox task is copying it into your test sandbox.
