使用传递的参数重命名gradle中的文件 [英] Rename file in gradle with passed parameter

问题描述

我正在从gradle版本中打包我的版本文物.这是一个Android Studio项目.

I'm packaging up my build artefacts from a gradle build. It's an Android Studio project.

我有一些任务可以成功创建一个包含两个jar的zip文件.假设zip文件名为"my.zip".

I have tasks that successfully create a zip file containing two jars. Let's say the zip file is called 'my.zip'.

我有以下gradle任务:

I have the following gradle task:

task renameArtifacts (type: Copy) {
    from ('build/')
    include 'my.zip'
    destinationDir file('build/')
    doLast {
        println "my-${versionString}.zip"
        rename('build/my.zip', "build/my-${versionString}.zip")
    }
}

我用gradle -PversionString="123" :sdk:renameArtifacts

我在doLast闭包中有一个println，可以看到我的字符串插值在输出my-123.zip时正常工作.

I have a println in the doLast closure and can see the my string interpolation is working correctly as it outputs my-123.zip.

但是，'my.zip'不会重命名为'my-123.zip'.它仍然是'my.zip'，实际上导致文件大小为零字节，并且不能再作为zip文件打开.

However, 'my.zip' is not renamed to 'my-123.zip'. It remains 'my.zip' and in fact results in a file with a size of zero bytes and is no longer openable as a zip file.

我显然在某个地方出错了，但是在哪里?

I'm obviously going wrong somewhere, but where?

推荐答案

rename是CopyProcessingSpec上的一种方法，该方法将任务配置为在操作时执行一些重命名.如果将其包装在doLast中，则复制已经发生，并且将不执行重命名.此外，重命名仅使用文件名，而不使用相对或绝对文件路径.这应该起作用:

rename is a method on CopyProcessingSpec, that configures the task to perform some renamings while operating. If you wrap it in doLast, the copying has already happened, and no rename will be performed. Furthermore, rename takes only file names, not relative or absolute file paths. This should work:

project.ext.versionString = versionString
task renameArtifacts (type: Copy) {
    from ('build/')
    include 'my.zip'
    destinationDir file('build/')
    rename 'my.zip', "my-${project.versionString}.zip"
}

$ versionString在任务中不可访问.建议使用额外的项目属性来在任务中传递这些属性(请参见这里).

$versionString is not accessible in tasks. Using extra project property is the suggested way how to pass these in tasks (see here).
