Build error: missing artifact com.sun:tools:jar:1.6

Trying to build PlayN sample projects I get:

Missing artifact com.sun:tools:jar:1.6  pom.xml /playn-cute line 6  Maven Dependency Problem

On every pom.xml file. How do I resolve it?

Edit:

I've added the profiles node to the pom.xml, but the error remains. I've checked the tools.jar is actually exists, and it didn't. So I've added tools.jar to lib folder. And still the error remains.

The full pom.xml:

This artifact is always handled as a 'system' dependency. It is never stored in a repo.

See https://web.archive.org/web/20151031071007/http://maven.apache.org/general.html#tools-jar-dependency for the details.

if there is no tools jar, and you aren't on a Mac, you are trying to use a JRE when the requirement is a JDK. You can't turn one into the other by copying file.
