我将sdk更新为27.1.0，但现在我想降级到27.0.2 我的build.gradle包含以下行：
return thisAppDb.ref('userRemindMatches/'+child.key+'/'+compId).on('value',(snapshot)=> {
但android工作室说，它发现了一些版本为27.1.0的lib，并且所有版本都必须具有相同版本。
另一个问题是我无法在apply plugin: 'com.android.application'
apply plugin: 'org.greenrobot.greendao'
apply plugin: 'project-report'
android {
