The former, now `@Deprecated` usage:

```groovy
tasks.named('test') {
    reports.junitXml.setDestination(layout.buildDirectory.file('reports/my-report-old').get().asFile) // DEPRECATED
}

```

can be replaced with:

```groovy
tasks.named('test') {
    reports.junitXml.outputLocation = layout.buildDirectory.dir('reports/my-report')
}
```
