 Description   

If I suppose correctly then gradle can only resolve dependencies that are declared with the default scope in a POM. This is not sufficient for us. So I wrote a task that resolves any dependency defined in a POM, creates a new configuration, resolves the dependencies and looks for some POMs and their dependencies and so on. The idea behind this task is to create a local repository (Please note, we can not use one of the commonly used repository managers.). This repository shall used by builds based on gradle and maven.

For each loop a new configuration is created and a dependency list is calculated by the task. With each loop this list gets larger and larger. The task is working very well for dependency to commons-logging version 1.1.1. Resolving spring-context version 3.1.2.RELEASE results in a NullPointerException (Stacktrace below). I tried to find out which transitive dependency is running into trouble. But if I resolve each transitive dependency with its own configuration, then everything is working very well.

Steps to reproduce: execute task 'retrieveAndParsePom' of attached script
NullPointerException:

* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':retrieveAndParsePom'.

I managed to reproduce the NPE. The NPE is also thrown for other gradle versions (I've tested 1.0-1.3).

Comment by Benjamin Muschko [ 15/Nov/16 ]

As announced on the Gradle blog we are planning to completely migrate issues from JIRA to GitHub.

We intend to prioritize issues that are actionable and impactful while working more closely with the community. Many of our JIRA issues are inactionable or irrelevant. We would like to request your help to ensure we can appropriately prioritize JIRA issues you’ve contributed to.

Please confirm that you still advocate for your JIRA issue before December 10th, 2016 by:

  • Checking that your issues contain requisite context, impact, behaviors, and examples as described in our published guidelines.
  • Leave a comment on the JIRA issue or open a new GitHub issue confirming that the above is complete.

We look forward to collaborating with you more closely on GitHub. Thank you for your contribution to Gradle!
