Quickstart

This quickstart is meant to be illustrative. For ideas on how to use degasolv in real life, have a look at Some Useful Recipes.

Given these artifacts:

• http://example.com/repo/a-1.0.zip
• http://example.com/repo/b-2.0.zip
• http://example.com/repo/b-3.0.zip

1. Generate dscard files to represent them in a degasolv respository, like this:

   $ java -jar degasolv-<version>-standalone.jar generate-card \
       --id "a" \
       --version "1.0" \
       --location "https://example.com/repo/a-1.0.zip" \
       --requirement "b>2.0" \
       --card-file "$PWD/a-1.0.zip.dscard"
   
   $ java -jar degasolv-<version>-standalone.jar generate-card \
       --id "b" \
       --version "2.0" \
       --location "https://example.com/repo/b-2.0.zip" \
       --card-file "$PWD/b-2.0.zip.dscard"
   
   $ java -jar degasolv-<version>-standalone.jar generate-card \
       --id "b" \
       --version "3.0" \
       --location "https://example.com/repo/b-3.0.zip" \
       --card-file "$PWD/b-2.0.zip.dscard"
   

2. Generate a dsrepo file from the cards:

   $ java -jar degasolv-<version>-standalone.jar \
       generate-repo-index \
       --search-directory $PWD \
       --index-file $PWD/index.dsrepo
   

3. Then use the dsrepo file to resolve dependencies:

   $ java -jar degasolv-<version>-standalone.jar \
       resolve-locations \
       --repository $PWD/index.dsrepo \
       --requirement "b"
   

   This should return something like this:

   a==1.0 @ http://example.com/repo/a-1.0.zip
   b==3.0 @ http://example.com/repo/b-3.0.zip
   

To see the help page, call degasolv or any of its subcommands with the -h option. If this is your first time using degasolv, it’s recommended that you read Some Useful Recipes.
