问题
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.
FAILURE: Build failed with an exception.

Where I'm wrong?
回答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')
}
}

Hi I got the following to run, but nothing seems to get check out
in the same directory of gradle.build I added a lib folder with the requisite jars
ant.path(id: 'svnant') {
ant.pathelement(location: 'antlib/svnClientAdapter.jar')
ant.pathelement(location: 'antlib/svnant.jar')
ant.pathelement(location: 'antlib/ganymed.jar')
ant.pathelement(location: 'antlib/jna.jar')
ant.pathelement(location: 'antlib/svnjavahl.jar')
}
