You can also use `-Dorg.gradle.internal.invalidate-coupled-projects=false` to force parallel configuration when there are access problems.

Please be aware that these options disable the validation that makes execution parallel- and caching-safe when isolated projects is enabled,
so you may see some unexpected behaviour when using them.
