问题 I have been grinding at this for hours on end. I seem to do everything right according to google and other answers to this same question, yet I still get no R.java file in my project. I appear to not have any errors in any of my resources. as soon as I remove the library reference in my project, the R file is generated again. The errors in the project are simply due to the lack of an R.java file. 回答1: Please check the console section. Sometimes there is a JAR mismatch. The JAR in the library

问题 In my Gradle script, I have created a Javadoc task that generates documentation for my java files and for the auto-generated R.java, so that it creates links for my XML resources.

Is there a way to document my XML

This caused my R.java file to disappear. I tried cleaning my project again, building it again, closing eclipse, deleting the gen folder, checking all of my xml files for errors, all of that. Problem now is whenever I create a new completely blank application project that doesn't even generate an R file
