Hi Raskolnikov,
Would you please add back the deleted part to the pom.xml and try the following command again:
mvn install:install-file -Dfile=ojdbc14.jar -DgroupId=com.oracle -DartifactId=ojdbc14 -Dversion=10.2.0.4.0 -Dpackaging=jar -DgeneratePom=true
The last parameter for generating a POM will save you from pom.xml warnings
And check if this works now?
