    java_library
    is an alias for 
    JavaLibrary
    , a target

    any task can choose to operate over 
    JavaLibrary
    targets in the graph when that task is executed

    JavaLibrary
    is a class of targets, right?

    The difference between a 
    Task
    and a 
    Goal
    is really the trickiest part here

    That's correct

    I think what's confusing me is http://pantsbuild.github.io/target_addresses.html explains that 
    examples/src/java/org/pantsbuild/example/hello/main:main
    is the address of a target
  • b

    bored-art-40741

    01/27/2016, 11:36 PM
    That is correct

    and the main target in that example is a 
    java_library
    target

    tasks are ‘verbs’ - things you do to a target. compile, test, etc.
  • r

    rough-minister-58256

    01/27/2016, 11:36 PM
    targets are nouns

    @rough-minister-58256: 
    compile
    is a goal which is a verb, right?
  • b

    01/27/2016, 11:37 PM
    Correct

    goals are almost 1:1 with tasks
  • r

    rough-minister-58256

    01/27/2016, 11:37 PM
    goals are how tasks are invoked
  • r

    rough-minister-58256

    01/27/2016, 11:37 PM
    yeah
  • b

    01/27/2016, 11:37 PM
    Tasks are not verbs, right?

    goals are the ‘entrypoint’ to a task, they’re usually 1:1

    Restating my earlier sentence. When I create a BUILD file, I'm using the 
    java_library
    thingy? to define a target named foo, and I use the 
    compile
    goal to invoke it. That's correct, right?

    java_library
    is not, itself, a target; the target is "foo"
  • b

    bored-art-40741

    01/27/2016, 11:39 PM
    Yes
  • b

    bored-art-40741

    01/27/2016, 11:39 PM
    All correct

    java_library is an alias, a target factory

    is there a Compile task?
  • b

    bored-art-40741

    01/27/2016, 11:39 PM
    It's a compile goal
  • b

    bored-art-40741

    Which has tasks like 
    ZincCompile
    and so on

    Frequently, for simple tasks, there is one task with the same name as the goal

    Taking a step back, like Kris said a goal is a verb, a target is a noun, and a task is sort of a sub-component of a goal that does one specific thing
