Bug#810817: gradle fails to install, because of circular dependency between maven core plugins

[Cyrille Chépélov]

Package: gradle
Version: 2.9-1 
Severity: normal

Dear Maintainer,

While building Cascading (https://github.com/cwensel/cascading), gradle
fails to run the following task

  LC_ALL=en_US.UTF-8 gradle clean install -x test -x platformTest --stacktrace 

(which works fine on Cascading's upstream CI suite), with the following
error message (abridged):

---------------------
:cascading-core:install FAILED

BUILD FAILED

----------------------

gradle 2.9-1 from Debian pulls in maven 3.3.9

When downloading gradle 2.10 binaries from https://www.gradle.com, the build as specified above proceeds fine. 
Gradle.com's binaries include maven 3.0.4, whereas the Debian package libgradle-plugins-java requires libmaven3-core-java (>= 3.3.3).

Thanks in advance

Hi Cyrille,

Thank you very much for reporting this issue.

Our Maven 3.3 integration is incomplete, Mikolaj Izdebski pointed out on
IRC that Fedora has additional changes solving this issue. We have to
use Sisu and enable auto-wiring to deal with the cycles.

Gradle 2.7 in the Jessie backports isn't affected by this issue since it
uses Maven 3.0.x.
