Gradle build time: Tuesday, May 7, 2013 9:12:14 AM UTC Groovy: 1.8.6 Ant: Apache Antâ„¢ version 1.8.4 compiled on May 22 2012 Ivy: 2.2.0 JVM: 1.7.0_17 (Oracle Corporation 23.7-b01) OS: Mac OS X 10.8.4 x86_64

Please find a minimal test case:

group = 'eu.plumbr'
  apply plugin: 'base'
  repositories {
  maven {
    url 'http://jcenter.bintray.com'
  }
}
  configurations {
  night
}
  dependencies {
  night group: 'eu.plumbr', name: 'plumbr', version: 'B1322', ext: 'txt'
}

With this build.gradle if I run

gradle dependencies

I get the NPE mentioned above. If I comment out first line, group declaration, then build runs just fine.

Hi Nikita,

Would you mind trying with the nightly?

There were a lot of Ivy issues resolved recently.


(Nikita Salnikov-Tarnovski) #4

Hi Luke. Yes, Gradle 1.7-20130702085240+0000 solves the problem. Thank you :slight_smile:
