Using gradlew 7.4, this `build.gradle` file:

```

apply plugin: 'java'



repositories {

    mavenCentral()

}



dependencies {

    implementation 'com.google.cloud:google-cloud-datastore:2.16.0'

    implementation 'com.google.guava:guava:32.1.1-jre'

}



print configurations.runtimeClasspath.files

...fails like this:

```

$ gradlew dependencies

It succeeds with 32.0.1-jre or if excluding the transitive listenablefuture dependency from datastore:

```

    implementation dependencies.create('com.google.cloud:google-cloud-datastore:2.16.0') {

        exclude group: 'com.google.guava', module: 'listenablefuture'

    }

```
