 Description   

Consider the following build script:
apply plugin: "java"
ext.libraries = [dependency: "commons-logging:commons-logging:1.1.1"]
dependencies

{ compile libraries.dependencyyyy // here is a typo }

I get such a stacktrace:

This is too unclear to understand what is wrong.

Are you running with one of the logging command-line options, such as -s or -d? You might see if the default output without these options solves your problem.

Comment by Dmitry Dobrynin [ 01/May/13 ]

Default output is
C:\temp\sld>g build

FAILURE: Build failed with an exception.

  • Where:
    Build file 'build.gradle' line: 4
  • What went wrong:
    A problem occurred evaluating root project 'sld'.
    > java.lang.NullPointerException (no error message)
  • Try:
    Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Though such a message is not a critical bug but obscure. Sure a message like 'You specified null as a dependency' is a little bit clearer.

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!
