Maven output:

Here is javadoc plugin configuration:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-javadoc-plugin</artifactId>
<version>2.7</version>
</plugin>
mvn --version:
Apache Maven 2.2.1 (r801777; 2009-08-06 21:16:01+0200)
Java version: 1.6.0_20
Java home: C:\Program Files\Java\jdk1.6.0_20\jre
Default locale: hr_HR, platform encoding: Cp1250
OS name: "windows 7" version: "6.1" arch: "amd64" Family: "windows"
How to solve this?
Thanks in advance.
