+## Adding local JARs as dependencies
+You can pass local JARs from the command line with the `--extra-jar` option:

+```bash ignore
+scala-cli compile Sample.sc \

+Local sources JARs can also be passed in a similar manner:

+scala-cli compile Sample.sc \
+  --extra-source-jar "./path/to/custom-sources.jar"

+Both can be handled with the appropriate `using` directives, too:

+:::caution
+Local JARs with the `*-sources.jar` suffix are assumed to be sources JARs and are treated as such.
