hello,

with this maven works fine in IntelliJ
    <dependency>
        <groupId>org.jopendocument</groupId>
        <artifactId>jOpenDocument</artifactId>
        <version>1.3</version>
    </dependency>

I have restarted KS and after that all should be in classpath but somehow KS not found this lib from classpath
