Explanation

The mvn dependency:list command produces a list of dependencies that's readable but not very program-friendly, looking like this:

[INFO] The following files have been resolved:
[INFO]    joda-time:joda-time:jar:2.3:compile
[INFO]    junit:junit:jar:4.11:test
[INFO]    log4j:log4j:jar:1.2.12:compile

A sed can shave off the extra formatting to turn this into:

joda-time:joda-time:jar:2.4
log4j:log4j:jar:1.2.12

Explanation:

  • -n don't print by default
  • -e s/..........// shave off the first 10 characters
  • -e /patterntoexclude/d you can exclude some unwanted patterns from the list using the d command like this
  • -e s/:compile//p -e s/:runtime//p replace and print :compile and :runtime

As multi-module projects may include duplicates, filter the result through | sort | uniq
