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

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