jdepend & gradle - NullPointerException

[Tomek Kaczanowski-3]

hi all,

I try to run jdepend from Gradle - with no luck.

I started with the simplest ant build.xml and tried to convert it to
build.gradle.

build.xml works. It looks like this:
<?xml version="1.0"?>
<project name="MyProject" default="jdepend" basedir=".">
  <target name="jdepend">
    <jdepend outputfile="build/docs/jdepend-report.txt">
      <exclude name="java.*"/>
      <exclude name="javax.*"/>
      <classespath>
        <pathelement location="build"/>
      </classespath>
      <classpath location="build"/>
    </jdepend>
  </target>
</project>




equivalent (I hope so) build.gradle:
usePlugin('java')

repositories {
    mavenCentral()
}

configurations {
    jdependConf
}

dependencies {
    jdependConf 'jdepend:jdepend:2.9.1', 'org.apache.ant:ant-jdepend:1.7.1'
}

task jdepend << {
    println 'Running jdepend quality metrics tool'
    ant {
      taskdef(name:'jdepend',
classname:'org.apache.tools.ant.taskdefs.optional.jdepend.JDependTask',
classpath: configurations.jdependConf.asPath)
jdepend (outputfile: 'build/docs/jdepend-report.txt') {
        exclude {
                name: 'java.*'
        }
        exclude {
                name: 'javax.*'
        }
        classespath {
                pathelement {
                        location: 'build'
                }
        }
        classpath {
                location: 'build'
        }
}


    }
}



execution of "gradle jdepend" ends up like this:
:jdepend
Running jdepend quality metrics tool
Trying to override old definition of datatype jdepend

FAILURE: Build failed with an exception.

* Where:
Build file '/home/tomek/docs/gradle/cookbook/jdepend/build.gradle' line: 19

* What went wrong:
Execution failed for task ':jdepend'.
Cause: java.lang.NullPointerException

* Try:
Run with -s or -d option to get more details. Run with -S option to
get the full (very verbose) stacktrace.

Any hints ? I guess I'm doing something pretty silly...

Your mapping of the nested elements is not quite right. Attributes of an
element need to be passed as arguments to the element method, rather
than in the method closure:

jdepend(outputfile: ...) {
    exclude(name: 'java.*')
    exclude(name: 'javax.*')
    classpath { pathelement(location: 'build') }
    classpath(location: 'build')  // though, these 2 classpath elements
do the same thing
}
