Android build java.lang.NullPointerException (无错误信息) org.gradle.api.ProjectConfigurationException BUILD FAILED

Question

这个 android 项目在 Windows 机器上创建，设置 MacOS 构建机器并从 Git 获取文件夹并在 Mac 中构建它。

这是我在mac上执行gradle时出现的问题。 org.gradle.api.ProjectConfigurationException:配置项目“:app”时出现问题是发生错误。

我在使用 JDK9(特别是 9.0.4)时遇到过这个问题。当我切换回 JDK8 时，gradle 命令成功了。这是一个使用 Gradle 4.4 构建的项目，目标 SDK 27 并使用 JavaVersion.VERSION_1_8 的源和目标兼容性。当我将它们切换回 1.7 兼容性时，问题就消失了。
