    internal val DEFAULT_REPOS = listOf(
            "<http://repo1.maven.org/maven2/>",
            "<https://maven-central.storage.googleapis.com/>",
            "<https://repository.jboss.org/nexus/content/repositories/root_repository/>",
            "<https://jcenter.bintray.com/>",
            "<http://repository.jetbrains.com/all/>",
            "<https://oss.sonatype.org/content/repositories/snapshots/>"
    )
```
