Gradle support for agent does not work.

[michael-simons]

Running

./gradlew -Pagent test   

followed by

./gradlew -Pagent nativeTest

does not work but ends with

> Task :nativeTestBuild FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':nativeTestBuild'.
> Agent output missing while `agent` option is set.
  Did you run the test task before with `-Pagent` enabled?

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

even though native files are generated:

 tree build/native 
build/native
└── agent-output
    └── test
        ├── jni-config.json
        ├── proxy-config.json
        ├── reflect-config.json
        ├── resource-config.json
        └── serialization-config.json

however the plugin tries to resolve

native-build-tools/native-gradle-plugin/src/main/java/org/graalvm/buildtools/Utils.java

Line 61 in a28d187

public static final String AGENT_OUTPUT_FOLDER = Paths.get(NATIVE_IMAGE_OUTPUT_FOLDER, "agent-output").toString();

with

native-build-tools/native-gradle-plugin/src/main/java/org/graalvm/buildtools/gradle/GradleUtils.java

Line 105 in a28d187

return project.getBuildDir().toPath().resolve(Utils.NATIVE_IMAGE_OUTPUT_FOLDER);

which is wrong in two places:

The test path is not in there but the native path will be resolved twice.

Moving the agent files into

tree build/native/native 
build/native/native
└── agent-output
    └── test
        ├── jni-config.json
        ├── proxy-config.json
        ├── reflect-config.json
        ├── resource-config.json
        └── serialization-config.json

"fixes" this…

Hi, Im getting the same error with 0.9.0 version

> Task :nativeTestBuild FAILED

My config:

plugins {
id 'org.graalvm.buildtools.native' version "0.9.0"

}
nativeTest {
    agent = true
    persistConfig = true
}

The folder src/main/resources/META-INF/native-image is already created.

is there a workaround?

Hey @jarpz! As a workaround for 0.9, could you try the running the tests like this:

./gradlew -Pagent nativeTest -DpersistConfig

Hey @jarpz! As a workaround for 0.9, could you try running the tests like this:

./gradlew -Pagent nativeTest -DpersistConfig

We got this:

WARNING: Could not resolve org.gradle.api.internal.tasks.testing.junit.AbstractJUnitSpec for serialization configuration.
Error: Cannot find serialization target class org.Gradle.api.internal.tasks.testing.junit.AbstractJUnitSpec. The missing of this class can't be ignored even if -H:+AllowIncompleteClasspath is set. Please make sure it is in the classpath
Error: Use -H:+ReportExceptionStackTraces to print stacktrace of underlying exception
Error: Image build request failed with exit status 1

I know we can customize the build but the problem is in the reflection-config.json, which are been including tests classes.

Is that right?

Also, the generated files are put in test/resources/** folder. those files are put in the main/resources/**, are they?
