Checkout svn using gradle

Question

I want to checkout svn using gradle. According to example I wrote this

task dwnSnark << {
    ant.path(id: 'svnant') {
        ant.pathelement(location: 'antlib/svnClientAdapter.jar')
        ant.pathelement(location: 'antlib/svnant.jar')
        ant.pathelement(location: 'antlib/svnkit.jar')
    }
    ant.taskdef(resource: 'org/tigris/subversion/svnant/svnantlib.xml', classpathref: 'svnant')
    mkdir('destpath')
    ant.svn(javahl: 'false', svnkit: 'true', username: 'user', password: 'pass', failonerror: 'false') {//this is actually line: 37 from stacktrace
        ant.checkout(url: 'svn://code.threerings.net/snark/trunk', destPath: 'destpath')
        ant.update(dir: 'destpath')
    }
}

But when I execute it. It throws exception.

gradle dwnSnark --stacktrace
:dwnSnark
[ant:taskdef] Could not load definitions from resource org/tigris/subversion/svnant/svnantlib.xml. It could not be found.

Where I'm wrong?

Answer 1

This slight modification seems to get it working. I've downloaded and unzipped the latest svntask into the project and declare the classpath directly for the taskdef instead of declaring the path separately.

task dwnSnark << {
    ant.taskdef(resource: 'org/tigris/subversion/svnant/svnantlib.xml') {
        classpath {
            fileset(dir: 'svnant-1.3.1/lib', includes: '*.jar')
        }
    }
    mkdir('destpath')
    ant.svn(javahl: 'false', svnkit: 'true', username: 'user', password: 'pass', failonerror: 'false') {
        ant.checkout(url: 'https://svn.java.net/svn/groovychart~svn', destPath: 'destpath')
        ant.update(dir: 'destpath')
    }
}
