generateLicenseInfo explicitly requests a pom for each dependency, but there isn't a pom in ivy repositories. This results in a build failure for a missing artifact:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':generateLicenseInfo'.
> Could not find <artifact-name>.pom (<group>:<artifact-name>:<version>).
  Searched in the following locations:
      <repo>

The workaround is to explicitly disable the task in your build.gradle:

generateLicenseInfo.enabled = false

I think it's desirable for the plugin to work by default if there are ivy repositories defined, and any of the following could be workable solutions:

• generateLicenseInfo.onlyIf { configurePublishing }
• generateLicenseInfo.onlyIf { all repositories are maven }
• issue a warning instead of failing if a pom cannot be found
