class Buildr::Packaging::Java::JarTask

Extends the ZipTask to create a JAR file.

This task supports two additional attributes: manifest and meta-inf.

The manifest attribute specifies how to create the MANIFEST.MF file.

A hash of manifest properties (name/value pairs).
An array of hashes, one for each section of the manifest.
A string providing the name of an existing manifest file.
A file task can be used the same way.
Proc or method called to return the contents of the manifest file.
False to not generate a manifest file.

The meta-inf attribute lists one or more files that should be copied into the META-INF directory.

For example:

package(:jar).with(:manifest=>'src/MANIFEST.MF')
package(:jar).meta_inf << file('README')

Public Instance Methods

with(options) → self click to toggle source

Additional Pass options to the task. Returns self. ZipTask itself does not support any options, but other tasks (e.g. JarTask, WarTask) do.

For example:

package(:jar).with(:manifest=>'MANIFEST_MF')

Calls superclass method Buildr::ArchiveTask#with

# File lib/buildr/java/packaging.rb, line 227
def with(*args)
  super args.pop if Hash === args.last
  fail 'package.with() should not contain nil values' if args.include? nil
  include :from=>args if args.size > 0
  self
