Just faced an issue that cannot find openvideoplayer in maven repositories to simple add this as dependency.
Here is how to do it without official repo.

1. Download core-bin ovp from this location http://openvideoplayer.sourceforge.net/downloads
2. Unpack from ‘bin’ folder ‘owp_core.swc’ file.
3. Run this command

mvn install:install-file -Dfile=/path/to/lib/owp_core.swc \
-DgroupId=org.openvideoplayer \
-DartifactId=ovp \
-Dversion=2.1.6 \
-Dpackaging=swc \
-DgeneratePom=true

4. Add dependency to your pom

<dependency>
  <groupId>org.openvideoplayer</groupId>
  <artifactId>ovp</artifactId>
  <version>2.1.6</version>
  <type>swc</type>
</dependency>

That’s it!
