svn - 使用 gradle 结帐 svn

Question

我想使用 gradle 结帐 svn。根据 example我写了这个

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')
    }
}

但是当我执行它时。它抛出异常。

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

我错在哪里？

Answer 1

这个轻微的修改似乎让它工作。我已经将最新的svntask下载并解压到项目中，并直接为taskdef声明类路径，而不是单独声明路径。

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')
    }
}
