java - Gradle android找不到符号上下文

Question

我有一个 java + kotlin android 项目，可以在 Android Studio 中构建并运行良好。我现在正在设置 CI，需要从终端运行 Gradle。但是当我运行./gradlew :app:lint时我收到很多这样的错误:

symbol:   class Context
location: class ConnectivityMonitor
e: /*******/LocalAppHistory.java:20: error: cannot find symbol
public boolean hasSeenOnboarding(Context context) {
                                 ^

我收到 Context, CognitoUserSession, Typeface, CognitoCachingCredentialsProvider... 相同类型的错误还有很多。它仅适用于app项目，没有其他模块。

app gradle.build文件:

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'

Answer 1

一旦我从 Kotlin 编译器切换 git 分支时遇到此错误，无法找到符号，我可能是错的。

我清除了缓存然后它就工作了，

rm -rf $HOME/.gradle/caches/

似乎在切换分支时缓存的先前分支文件造成了此问题。

如果你愿意，可以尝试一下。
