A quick&dirtyquick-and-dirty batch solution (based on Alex's answerAlex's answer):
libs.bat
@ECHO OFF FOR %%I IN (*.jar) DO ( echo ^<dependency^> echo ^<groupId^>local.dummy^</groupId^> echo ^<artifactId^>%%I^</artifactId^> echo ^<version^>0.0.1^</version^> echo ^<scope^>system^</scope^> echo ^<systemPath^>${project.basedir}/lib/%%I^</systemPath^> echo ^</dependency^> ) Execute it like this: libs.bat > libs.txt. Then open libs.txt and copy its content as dependencies.
In my case, I only needed the libraries to compile my code, and this solution was the best for that purpose.
