Repro: Use this dependency file:

dependencies:
  com.google.guava:
    guava:
      version: 26.0-jre
      lang: java

bazel run  //:parse -- generate -r /home/me/Projects/foo -s 3rdparty/workspace.bzl -d dependencies.yml

Expected: Correct dependency for guava in 3rdparty/jbm/com/google/guava

Actual:

INFO: Build completed successfully, 1 total action wrote 6 targets in 6 BUILD files

workspace.bzl has these dependencies:

def list_dependencies():
    return [
    {"artifact": "com.google.code.findbugs:jsr305:3.0.2", "lang": "java", "sha1": "25ea2e8b0c338a877313bd4672d3fe056ea78f0d", "repository": "http://central.maven.org/maven2/", "name": "com_google_code_findbugs_jsr305", "actual": "@com_google_code_findbugs_jsr305//jar", "bind": "jar/com/google/code/findbugs/jsr305"},

    ]

And the workspace basically fails to load

% bazel info release release 0.18.0

Digging into existing bugs, it could be a duplicate of #184

[regisd]

Yes, workaround is to add these options in dependencies.yml:

options:
  languages: ["java"]
  resolverType: "coursier"

Yeah it seems aether is currently broken.

I’m very inclined to remove aether because it has other bugs we’ve found as well and requires new features to be written twice.
