Function of Project Clean in Eclipse

Question

What does Eclipse s Project  rarr  Clean    tool actually do

User · Answer

It removes whatever already-compiled files are in your project so that you can do a complete fresh rebuild

User · Answer

Its function depends on the builders that you have in your project  they can choose to interpret clean command however they like  and whether you have auto-build turned on  If auto-build is on  invoking clean is equivalent of a clean build  First artifacts are removed  then a full build is invoked  If auto-build is off  clean will remove the artifacts and stop  You can then invoke build manually later

I also faced the same issue with Eclipse when I ran the clean build with Maven  but there is a simple solution for this issue  We just need to run Maven update and then build or direct run the application  I hope it will solve the problem

There s another problem at work here  The Clean functionality of Eclipse is broken  If you delete files outside of Eclipse it will not pick up on the fact that the files are now missing  and you ll get build errors until you delete the files manually  Even then  that will not necessarily work either  especially if there are a lot of files missing  This happens to me rather often when I check out a branch of code that has had a lot of changes since the last time I built it  In that case  the only recourse I ve found is to start a brand new workspace and reload the project from scratch
