Hi,
I just wrote my first gradle plugin to integrate a specific parser generator
into our builds. The parser generator uses velocity 1.6.2 and velocity has a
dependency to log4j 1.2.12.
Now as soon as the parser generator initializes velocity I am getting the
following exception:
Caused by: org.codehaus.groovy.runtime.InvokerInvocationException:
java.lang.NoSuchMethodError: org.apache.log4j.Logger.setAdditivity(Z)V

In my build.gradle I even added log4j as compile time dependency:
apply plugin: "groovy"
repositories
{
mavenCentral()
mavenRepo urls: "http://maven.hello2morrow.com/repository";
mavenRepo urls: "http://repo.gradle.org/gradle/libs";
}
dependencies
{
compile group: 'log4j', name: 'log4j', version: '1.2.12'
compile group: 'com.hello2morrow', name: 'javapg', version: '3.0'
compile gradleApi()
groovy localGroovy()
}
But that does not help. Googling the exception brings an association with slf4j
log4j bridge jar. Is that jar used by gradle? Is there any way to make velocity
run within the context of a gradle plugin?
Thanks for any help in advance. And kudos for the gradle team for creating this
marvelous gem.
Best regards
