Extend Lockfile checker and generator

[pombredanne]

As a follow up to:

• DEPLOCK: Create initial Lockfile checker and generator  #2

Here are the next candidates:

• Java:
  • Maven Create Maven "lockfile" using built-in from maven.... It supports a dot, graphml and tgf output format. (And soon JSON!) #6
    • See also https://github.com/search?q=maven+dependency+tree&type=repositories
    • Note that the mvn dependency:tree command would typically process all pom.xml in the codebase at once, and would generate one tree for each each pom.xml
    • a good set of args to run the command would be : mvn dependency:tree -DoutputFile=maven-dependency-tree.lock -DoutputType=graphml and optionally with-Dmaven.test.skip=true and -DskipTests to skip tests, or various other options (such as scope) to filter the tree. See https://maven.apache.org/plugins/maven-dependency-plugin/tree-mojo.html
  • Gradle Create Gradle gradle.lockfile using built-in features and #9
    • See https://docs.gradle.org/current/userguide/dependency_locking.html
    • https://github.com/GeekMasher/gradle-lock-dependency-submission-action
• Other:
  • Create composer lock file with composer
  • Create Ruby lock file with bundler
  • Create go.sum lock file with go (though this should be standard by now)
  • Create cargo/Rust lock file
  • Create Dart/pub lockfile
