Unzip Archive with Groovy

Maybe Groovy doesn’t have ‘native’ support for zip files, but it is still pretty trivial to work with them.

I’m working with zip files and the following is some of the logic I’m using:

def zipFile = new java.util.zip.ZipFile(new File('some.zip'))

zipFile.entries().each {
   println zipFile.getInputStream(it).text
}

You can add additional logic using a findAll method:

def zipFile = new java.util.zip.ZipFile(new File('some.zip'))

zipFile.entries().findAll { !it.directory }.each {
   println zipFile.getInputStream(it).text
}
