java – Android：执行单元测试时Android支持中的IllegalStateException

我正在尝试在Andoid studio中运行一些单元测试.在“运行配置”选项卡中,我已将其设置为使我的JUnit在整个项目中搜索测试.我的JRE配置为1.8,我已启用代码覆盖率.但是,每次我尝试运行测试时,都会出现以下“IDE致命错误”：

Unable to determine list of modules to build
java.lang.IllegalStateException: Unable to determine list of modules to build

    at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)
    at java.lang.Thread.run(Thread.java:745)

我试图谷歌一个解决方案,这个线程接近：NullPointerExcepton in Android Studio plugin Android Support,但我的SDK和插件是最新的,并没有真正解决它.

谢谢
