gradle - svnant的嵌套复制任务无法在gradle中工作

Question

我是gradle和groovy的新手，现在我尝试在Subversion存储库中设置标签。以下是我的gradle脚本:

task svnrev {
    // use ant to retrieve revision.
    ant.taskdef(resource: 'org/tigris/subversion/svnant/svnantlib.xml') {
        classpath {
            fileset(dir: 'lib/DEV/svnant', includes: '*.jar')
        }
    }
    ant.svn(javahl: 'false', svnkit: 'true', username: "${_svn_user}", password: "${_svn_password}", failonerror: 'false') {
        ant.info(target: "${_svn_source_url}", propPrefix: 'svninfo')
    }
    // retrieve property of ant project and assign it to a task's property, refer to:
    // http://gradle.1045684.n5.nabble.com/can-t-find-or-extract-properties-from-svnant-info-function-in-gradle-td3335388.html
    ext.lastRev = ant.getProject().properties['svninfo.lastRev']
    // retrieve property of gradle project
    //getProject().properties['buildFile']
    }

task svntag << {
    ant.svn(javahl: 'false', svnkit: 'true', username: "${_svn_user}", password: "${_svn_password}", failonerror: 'false') {
        copy(srcurl: "${_svn_source_url}", desturl="${_svn_tag_url}", message="Create tag: ${_svn_tag_url}")
    }
}

任务“svnrev”正常工作，但是当运行“gradle svntag”时，我不断收到错误消息:

* What went wrong:
A problem occurred evaluating root project 'AFM-IGPE-v2.0.0'.
> Could not find method copy() for arguments     [{srcurl=svn://192.168.2.9/IGPE/trunk_dev}, svn://192.168.2.9/IGPE/tag/AFM, Create tag: svn://192.168.2.9/IGPE/tag/AFM] on root project 'AFM-IGPE-v2.0.0'.

我也尝试过

ant.copy(srcurl: "${_svn_source_url}", desturl="${_svn_tag_url}", message="Create tag: ${_svn_tag_url}")

这次显示了另一条错误消息:

* What went wrong:
A problem occurred evaluating root project 'AFM-IGPE-v2.0.0'.
> No signature of method: org.gradle.api.internal.project.DefaultAntBuilder.copy() is applicable for argument types: (java.util.LinkedHashMap, org.codehaus.groovy.runtime.GStringImpl, org.codehaus.groovy.runtime.GStringImpl) values: [[srcurl:svn://192.168.2.9/IGPE/trunk_dev], ...]
Possible solutions: any(), notify(), wait(), grep(), every(), find()

实际上，我只是简单地将ant build.xml转换为gradle，而我的ant build.xml效果很好。我已经搜索了一段时间，但是没有找到结果。请帮助，并提前感谢您的帮助。

乍一看，我可以发现两个问题:

必须是task svnrev << {，而不是task svnrev {。

Groovy命名参数是使用:而不是=编写的。 (相反，后者将默认值分配给位置参数。)这可能就是为什么会收到ant.copy错误的原因(您在:和=之间混合和匹配)。
