Scripts

The following script is available.

searchJars

This script will find jar files found on the directory passed as argument and subdirectories, will calculate its checksums and search for them in Maven Central repository.

The output is written to console, tab separated, it can be redirected to a file if desired. e.g.:

./searchJars.sh /project_dir/libs > output.tsv
