启用androidX原因'；无法更改配置的策略'；：应用程序：编译'；解决后'；错误

我目前正在尝试将OpenId/Android Apputh迁移到androidX，在执行所有更改后，我遇到了一个奇怪的问题gradle开始抛出以下错误：

> Cannot change strategy of configuration ':app:compile' after it has been resolved.

我加上

android.enableJetifier=true
android.useAndroidX=true

到“gradle.properties”

提示

我尝试记录所有可能的配置块（使用

println（cofigBlockName）

），发现在构建过程中没有调用

sourceset

configBlock。因此，Jetifier可能会将一些设置应用于

sourceset

有人知道怎么解决吗

这项工作对我来说很好：

实现'com.google.android.exoplayer:exoplayer核心：2.10.2'
实现'com.google.android.exoplayer:exoplayer dash:2.10.2'
实现'com.google.android.exoplayer:exoplayer用户界面：2.9.6'
实现'com.google.android.exoplayer:exoplayer smoothstreaming:2.10.2'

我也面临类似的问题。在我的例子中，java语言级别存在问题，注释处理器在java 9+上运行，而android编译为java 8或更低版本。因此，将org.gradle.java.home添加到构建选项起到了作用：

./gradlew--info--scan--stacktrace--debug:app:clean:app:compiledBugSources-Dorg.gradle.java.home=/Applications/Android\Studio.app/Contents/jre/jdk/Contents/home

希望这有帮助

我也在为同样的事情挣扎。。。正在寻找一个解决方案……您是否设法解决了这个问题？android stuido提供了迁移到androidX的选项。你试过了吗？这个问题最终解决了吗？
