maven-resources-plugin:2.5 - Cannot create resource output directory

Question

I occasionally receive this error when I build my project with

>mvn --version
Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602         


        

Answer 1

On Windows, there reasons for being unable to create a folder are:

1. Some other process is deleting this folder at the same time
2. You don't have permissions to access this folder
3. The folder is on a network share

Network shares are notoriously unreliable on Windows. Don't use them for any automated tasks. Always build projects with all files residing on a local hard disk.

If you use Maven and Eclipse to build at the same time, you should configure them to use different target folders. See https://stackoverflow.com/a/54366009/34088

Your POM should look like this:

  ...

  
    ${basedir}/${target.dir}/classes
    ${basedir}/${target.dir}/test-classes
  

  
    target
  

  
    
      eclipse-folders
      
        target-eclipse
      
    
  
  ...  

All that's left is to enable the profile eclipse-folders in the IDE.
