solved by deleting the target folder manually

User · Answer

Your problem is that a running process within STS is using files located in your target directory while you execute a mvn clean command  Maven will be unable to delete these files  since other processes are still accessing them  and thus fail with that error   Try to stop all processes  tests  servers  applications  from within STS before running Maven console commands  Look out  This behaviour might also appear if STS is cleaning up the projects and thus re-compiles the sources  and not running a process

For linux users  possible solution   Build error due to  Failed to delete  lt  any-file-or-folder    will occur if there is by chance of only delete access provided to root user rather to normal-user   Fix   type ll command to list file that cannot be deleted  if the file is given root access  change to normal user by        sudo chown -R user-name user-name filename   Later try for maven clean and build
