[Anonymous]

Я пишу тесты для класса, который требует наличия определенных компонентов Android.
Используемые версии:
robolectric: 4.10.3
powermock: 2.0. 9
Я получаю эту ошибку

Я попробовал добавить следующее в testOptions в build.gradle, но это не помогло
all {
jvmArgs '--add-opens=java.base/java.lang.reflect=ALL-UNNAMED',
'--add-opens=java.base/java.lang=ALL-UNNAMED',
'--add-opens=java.base/java.util=ALL-UNNAMED'
}
