Reason and solution-  Everything happens for a reason      ERROR  Failed to execute goal org apache maven plugins maven-clean-plugin 3 1 0 clean  default-clean  on project   The reason of this problem is that the target folder is already in use  That means any jar or any war or any application is using that target folder   Solution- 1  Check the war and jar  also check jar if any running in background   terminate it   2  if u have opened command prompt  cmd   and are using that path to execute the jar  close it or change the path in cmd  This was the reason in my case  Do check this   Once u do this   u would be able to delete the contents of the target folder and and can also perform maven clean and maven install

I ve noticed that sometimes eclipse somehow picks up some of the jars and keeps a lock on them  in Windows only  and when you try to do mvn clean it says    ERROR  Failed to execute goal org apache maven plugins maven-clean-plugin 2 2 clean  default-clean  on project  The only solution so far is to close eclipse and run the mvn build again   And these are random jars - it can pick up anything it wants     Why that happens is a mystery to me  Probably eclipse opens the jars when you do Type Search or Resource Search and forgets to close them   release the file handlers

Try changing the permissions on the workspace folder  Make sure you have sufficient permissions to delete files in this folder  I faced the same problem and when i provided full control over the project folder  changing windows security permissions   it worked fine for me   Just to update  this morning it again started giving the same error even when i have given all the permissions  So i tried to delete the particular file  pointed in the error logs  manually to find out what s exactly the problem   I got the error  can not delete file because it s in use by Java TM SE   So the file was being used by java process due to which eclipse was not able to delete it   I closed the java process from task manager and after that it worked fine  Although its kinda hectic to close the java process every time I need to execute my project  its the working solution right now for me

Solution 1  Sometimes the build fails because  the target folder cannot be deleted   It might be open in the backend due to the previous builds    -  Open Task Manager  -  In the Process tab  -  Do  End Process  for the running  java exe  processess Solution 2   -  Restart eclipse  -  Perform Maven Build with command   clean install -DSkipTests

On Windows  I got  Unable to delete directory   What s wrong  For instance  clean could fail if you already have opened a command line with target as the current dir  Windows locks some ressources and you need to close the handles on these ressources   This works for me
