Oh no 😞 Could I see your

Copy code

jar_library(name='paradise',
  jars=[
    jar(org='org.scalamacros', name='paradise_2.12.7', rev='2.1.1'),
  ],
)

this is the BUILD at the root

brief-engineer-67497

10/19/2018, 3:52 PM

Copy code

jar_library(
  name = 'scalac-plugin-dep',
  jars = [
    jar(org='org.spire-math', name='kind-projector_2.12', rev='0.9.8'),
    jar(org='org.scalamacros', name='paradise_2.12.7', rev='2.1.1'),

)

10/19/2018, 3:52 PM

so there is two dependencies

brief-engineer-67497

10/19/2018, 3:53 PM

should I tag the one in

3rdparty/jvm/org/scalamacros/BUILD

runtime ?

brief-engineer-67497

10/19/2018, 3:53 PM

I'm migrating from an sbt conf

brief-engineer-67497

10/19/2018, 3:53 PM

and in sbt it has two be declared twice, as a compiler plugin and as a runtime dependency

red-balloon-89377

10/19/2018, 3:55 PM

So what I’d recommend is to just delete one of the jars (possibly the one in

scalac-plugin-dep

) and add a dependency to paradise. Not your final answer, but maybe worth a shot.

the runtime scope trick works !

red-balloon-89377

10/19/2018, 3:57 PM

Cool!

brief-engineer-67497

10/19/2018, 3:57 PM

I need to declare it in the

scalac-plugin-dep

: https://www.pantsbuild.org/scalac_plugins.html

brief-engineer-67497

10/19/2018, 3:58 PM

Hi, I'm having trouble to register a repository plugin. In pants.ini I have the following setting :

Copy code

[GLOBAL]
pants_version: 1.9.0
pythonpath: [
    '%(buildroot)s/pants-plugins',
  ]

backend_packages: [
     'foo'
  ]

in ./pants-plugins/foo/register.py

Copy code

# . . .
def build_file_aliases():
  return BuildFileAliases(
    objects={
      'nexus': foo_repo,  
      'testing': testing_repo,
    },
  )

brief-engineer-67497

10/22/2018, 1:24 PM

as is, I have an Invalid scope error

brief-engineer-67497

10/22/2018, 1:25 PM

the culprit is

backend_packages

brief-engineer-67497

10/22/2018, 1:26 PM

then if keep the same pants.ini, backend_packages included, but I replace

Copy code

def build_file_aliases():
 return BuildFileAliases(
   objects={

Copy code

def build_file_aliases():
 return BuildFileAliases(
   targets={

brief-engineer-67497

10/22/2018, 1:28 PM

I got the following error

Copy code

Exception message: Entrypoint build_file_aliases in foo.register must be a zero-arg callable: Only Target types and TargetMacro.Factory instances can be registered via the `targets` parameter, given item u'nexus' with value nexus -> <https://sf-nexus.foo.com/> (build-support/ivy/pushdb) of type Repository

I don't usually do python so I'm a bit lost

brief-engineer-67497

10/22/2018, 1:46 PM

got it !

brief-engineer-67497

10/22/2018, 1:46 PM

I was missing the + in

backend_packages: +[

brief-engineer-67497

10/22/2018, 1:47 PM

however, it's not mentioned in the documentation: https://www.pantsbuild.org/howto_plugin.html 😕
