gradle project sync failed ; 这个问题怎么解决呢？

Configuration 'compile' is obsolete and has been replaced with 'implementation' and 'api'.

It will be removed at the end of 2018. For more information see: http://d.android.com/r/tools/update-dependency-configurations.html

Unable to resolve dependency for ':ui_dialog@debug/compileClasspath': Could not resolve project :ui_menudemo.
