Ergonomic, hermetic, user-friendly software build system for Python, Go, Java, Kotlin, Protobuf, Scala, Shell. Pants lets you fearlessly scale up your codebase!

Pants

I think a concrete example will illustrate

OK, so `compile_classpath` and `runtime_classpath` are "products." `foo.jar` has a compile classpath and a runtime classpath

Within `test`, there is a task called `JunitRun` which, at effectively static scope, declares that it _needs_ the `runtime_classpath` product.  After all, you can't run tests if you don't have a classpath to run the JVM with.

`bar.jar` also has a compile classpath and a runtime classpath

Pants then says, "who provides `runtime_classpath`" ?

`ZincCompile`, a task under the goal `compile` says "I do" (or really, has already said so, since these are basically static annotations)

`ZincCompile` also says, "In order to run, I need a `compile_classpath` product"

I think my confusion was around your use of the word "product"

Pants then says, "who provides `compile_classpath`", and `IvyResolve` a task in the `resolve` goal says "I do"

Assuming (for simplicity) that `IvyResolve` has no products it needs, pants then says

OK, so the goal graph of "products" are of thingies like `compile_classpath` and not of thingies like "foo.jar"

"Okay, I will run `resolve` and then `compile` and then `test`"

And it _doesn't care about the target graph at all_

This is a totally separate graph, just there to schedule the minimal set of goals to run in the correct order

I thought foo.jar was a product, and so I wrongly said <https://pantsbuild.slack.com/archives/general/p1453938303000604>

yeah, you can see the linearized goal graph in pants output:

it's a file that I wanted the build to build.

```               Executing tasks in goals: bootstrap -&gt; imports -&gt; unpack-jars -&gt; deferred-sources -&gt; compute-buildprops -&gt; jvm-platform-validate -&gt; gen -&gt; resolve -&gt; resources -&gt; buildprops -&gt; compile -&gt; test```

In other build systems, you might say that foo.jar is a "target" but I don't know what I'd call it in pants
