maven-resources-plugin:2.6 - Cannot create resource output directory

Question

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

[ec2-user@ip-xxx-xxx-xxx-xxx aws-java-sample]$ mvn clean compile exec:java

I've seen the question similar to this on Stack Overflow, but that is using Windows as its host where I'm using a Linux instance. Plus that answer involves configuration with Eclipse, which I am not using. I'm not sure why it's behaving like this nor know how to fix it.

Answer 1

I my case this error appeared when I had target directory opened in console (so maven cannot delete it).
Navigating out of the target folder allowed me to install via maven without a problem.
