如何在Gradle中压缩单个文件？

Question

How to compress a single file inside a Copy task without having extra headache with creating and compressing temporary files manually?

For example, when you build a deb package, you should compress some files with gzip :

task buildDeb(type: Deb, dependsOn: ['jar']) {

    // ...

    from (file('packaging/deb-package/manpage')) {

        into '/usr/share/man/man1'
        //rename(/.*/, deploymentName + '.1.gz')
        rename(/.*/, deploymentName + '.1')

        filteringCharset = 'UTF-8'
        filter(ReplaceTokens, tokens: [
            'TITLE': appTitle,
            // ...
        ])

        // XXX
        //compressItWithGzip();

    }

    // ...

}

The built-in ant tools support only text filtering via the Reader interface. So, how to do something like compressing (or, in general, any binary manipulation)?

Answer 1

You can try:

ant.gzip(src: <source>, zipfile: <target>) 

in you task, catch the docs .

Also, maybe instead of putting too much logic in a single task, define a set of tasks (one would be responsible for this gzipping) and tie them with dependencies.
