Maven-resources-plugin: 2.6 - Unable to create resource output directory

So, I just created a Linux instance from EC2, and now I'm trying to install the AWS Java SDK on it. I am at the end of the installation when I run mvn clean compile exec:java and get the following:

 [ ec2-user@ip-xxx-xxx-xxx-xxx aws-java-sample]$ mvn clean compile exec:java [INFO] Scanning for projects...

I saw a question similar to this one in Stack Overflow, but it uses Windows as its host, where I use a Linux instance. Also, this answer includes a configuration with Eclipse that I am not using. I am not sure why this is so, and I do not know how to fix it.

In my case, this error appeared when I had the target directory open in the console (so maven cannot delete it).
Going from the destination folder allowed me to install through maven without any problems.

Try disabling the automatic assembly of your IDE; there may be a conflict with the Maven assembly. Also check that the folder is not open somewhere with Explorer or other applications. If it does not work, just restart the IDE
