У меня есть многомодульный проект Gradle 4.4 - есть родительский build.gradle, а затем два дочерних проекта Gradle, каждый со своим build.gradle.Оба являются проектами Java (один для кода разработчика, другой для обеспечения качества).Проект dev является зависимостью от проекта QA (у меня testCompile project(':dev-project') в build.gradle проекта QA).В противном случае нет ничего интересного или необычного в файлах build.gradle - они импортируют плагин java и com.github.johnrengelman.shadow.
Если я пытаюсь собрать родительский проект дважды подряд (без открытых IDE,при запуске ./gradlew clean build из Git Bash без прав администратора) сборка завершается неудачно:

Я подозреваю, что dev-project JAR невозможно удалить, поскольку он зависит от проекта QA, и поэтому Gradleсохраняет некоторую блокировку.
Я могу успешно построить, если удаляю процесс Java(TM) Platform SE Binary в диспетчере задач Windows, но я бы хотел, чтобы он был автоматическим.
