pomDependencyGenerator

An utility script to iterate over jars in a directory and generates related pom entries.
Helpful if you are migrating from ant to Maven.

**Note: ** Works with MavenCentral only.

How it works??

1. Script iterates on directory passed as command-line argument.
2. For each jar file :

• First tries to query "Maven central" with sha1 checksum of the jar file.
• If fails to identify with sha1, it switches to artifact & version search.
  • For each combination from jar name (Combinations using separator '-')
    • Query "Maven central" with artifactName and version.
    • On success returns result
• If search is successful hit (found exact match) from either of the above methods, writes "dependency" markup entry at input directory.
• If search is unsuccessful (happens 1/10 jars) writes a "dependency" mark-up entry with artifactId as Jar name.

Usage:

python pomDependencyGenerator.py "< Absolute path to directory where your jar files are >"

Example:
