任务'：app：compileDebugJavaWithJavac'的AndroidStudio执行失败

Question

我试图在AndroidStudio 3.0.1中构建一个示例应用程序，该示例应用程序使用私有Maven存储库中的库依赖项。 两个模块都使用compileSdkVersion和targetSdkVersion作为27。我没有在gradle中指定buildToolsVersion ，但是我的sdk-manager中安装了构建工具版本27.0.3 。

我看着这个和这个 ，但没有为我工作。

我正在使用Mac，并且也在bash配置文件中设置了JAVA_HOME。 我收到的错误是带有以下消息的编译错误：

Error:(66, 56) error: cannot find symbol variable M

更新 ：这是Gradle控制台的例外

似乎问题出在我正在使用的依赖项之一

implementation('com.github.tony19:logback-android-classic:1.1.1-6') {
        exclude group: 'com.google.android', module: 'android'
    }

它不包括android模块。 库中最近有更新，更新库后问题不再存在，该库不再排除android模块。
