Instance Method Details

#artifact(spec, &block) ⇒ Object

:call-seq:

artifact(spec) => Artifact
artifact(spec) { |task| ... } => Artifact

Creates a file task to download and install the specified artifact in the local repository.

You can use a String or a Hash for the artifact specification. The file task will point at the artifact’s path inside the local repository. You can then use this tasks as a prerequisite for other tasks.

This task will download and install the artifact only once. In fact, it will download and install the artifact if the artifact does not already exist. You can enhance it if you have a different way of creating the artifact in the local repository. See Artifact for more details.

For example, to specify an artifact:

artifact('log4j:log4j:jar:1.1')

To use the artifact in a task:

compile.with artifact('log4j:log4j:jar:1.1')

To specify an artifact and the means for creating it:

download(artifact('dojo:dojo-widget:zip:2.0')=>
  'http://download.dojotoolkit.org/release-2.0/dojo-2.0-widget.zip')

#artifact_ns(name = nil, &block) ⇒ Object

:call-seq:

project.artifact_ns -> ArtifactNamespace
Buildr.artifact_ns(name) -> ArtifactNamespace
Buildr.artifact_ns -> ArtifactNamespace for the currently running Project

Open an ArtifactNamespace. If a block is provided, the namespace is yielded to it.

#artifacts(*specs, &block) ⇒ Object

:call-seq:

artifacts(*spec) => artifacts

Handles multiple artifacts at a time. This method is the plural equivalent of #artifact, but can do more things.

Returns an array of artifacts built using the supplied specifications, each of which can be:

  • An artifact specification (String or Hash). Returns the appropriate Artifact task.

  • An artifact of any other task. Returns the task as is.

  • A project. Returns all artifacts created (packaged) by that project.

  • A string. Returns that string, assumed to be a file name.

  • An array of artifacts or a Struct.

  • A symbol. Returns the named artifact from the current ArtifactNamespace

For example, handling a collection of artifacts:

xml = [ xerces, xalan, jaxp ]
ws = [ axis, jax-ws, jaxb ]
db = [ jpa, mysql, sqltools ]
artifacts(xml, ws, db)

Using artifacts created by a project:

artifacts project('my-app')               # All packages
artifacts project('my-app').package(:war) # Only the WAR

#concat(args) ⇒ Object

:call-seq:

concat(target=>files) => task

Creates and returns a file task that concatenates all its prerequisites to create a new file. See #ConcatTask.

For example:

concat("master.sql"=>["users.sql", "orders.sql", reports.sql"]

  ConcatTask.define_task(File.expand_path(file)=>deps)
end

#define(name, properties = nil, &block) ⇒ Object

:call-seq:

define(name, properties?) { |project| ... } => project

Defines a new project.

The first argument is the project name. Each project must have a unique name. For a sub-project, the actual project name is created by prefixing the parent project’s name.

The second argument is optional and contains a hash or properties that are set on the project. You can only use properties that are supported by the project definition, e.g. :group and :version. You can also set these properties from the project definition.

You pass a block that is executed in the context of the project definition. This block is used to define the project and tasks that are part of the project. Do not perform any work inside the project itself, as it will execute each time the Buildfile is loaded. Instead, use it to create and extend tasks that are related to the project.

For example:

define 'foo', :version=>'1.0' do

  define 'bar' do
    compile.with 'org.apache.axis2:axis2:jar:1.1'
  end
end

puts project('foo').version
=> '1.0'
puts project('foo:bar').compile.classpath.map(&:to_spec)
=> 'org.apache.axis2:axis2:jar:1.1'
% buildr build
=> Compiling 14 source files in foo:bar

  Project.define(name, properties, &block)
end

#download(args) ⇒ Object

:call-seq:

download(url_or_uri) => task
download(path=>url_or_uri) =>task

Create a task that will download a file from a URL.

Takes a single argument, a hash with one pair. The key is the file being created, the value if the URL to download. The task executes only if the file does not exist; the URL is not checked for updates.

The task will show download progress on the console; if there are MD5/SHA1 checksums on the server it will verify the download before saving it.

For example:

download 'image.jpg'=>'http://example.com/theme/image.jpg'

    end
  end

end

#filter(*sources) ⇒ Object

:call-seq:

filter(*source) => Filter

Creates a filter that will copy files from the source directory(ies) into the target directory. You can extend the filter to modify files by mapping ${key} into values in each of the copied files, and by including or excluding specific files.

A filter is not a task, you must call the Filter#run method to execute it.

For example, to copy all files from one directory to another:

filter('src/files').into('target/classes').run

To include only the text files, and replace each instance of ${build} with the current date/time:

filter('src/files').into('target/classes').include('*.txt').using('build'=>Time.now).run

end

#group(*args) ⇒ Object

:call-seq:

group(ids, :under=>group_name, :version=>number) => artifacts

Convenience method for defining multiple artifacts that belong to the same group, type and version. Accepts multiple artifact identifiers followed by two or three hash values:

  • :under – The group identifier

  • :version – The version number

  • :type – The artifact type (optional)

For example:

group 'xbean', 'xbean_xpath', 'xmlpublic', :under=>'xmlbeans', :version=>'2.1.0'

Or:

group %w{xbean xbean_xpath xmlpublic}, :under=>'xmlbeans', :version=>'2.1.0'

#install(*args, &block) ⇒ Object

:call-seq:

install(artifacts)

Installs the specified artifacts in the local repository as part of the install task.

You can use this to install various files in the local repository, for example:

install artifact('group:id:jar:1.0').from('some_jar.jar')
$ buildr install

    end
  end
end

#integration(*deps, &block) ⇒ Object

integration { |task| .... }
integration => IntegrationTestTask

Use this method to return the integration tests task.



711
712

# File 'lib/buildr/core/test.rb', line 711

def integration(*deps, &block)
  Rake::Task['rake:integration'].enhance deps, &block

# File 'lib/buildr/core/environment.rb', line 125

def options
  Buildr.options
end

#project(*args) ⇒ Object

:call-seq:

project(name) => project

Returns a project definition.

When called from outside a project definition, must reference the project by its full name, e.g. ‘foo:bar’ to access the sub-project ‘bar’ in ‘foo’. When called from inside a project, relative names are sufficient, e.g. project('foo').project('bar') will find the sub-project ‘bar’ in ‘foo’.

You cannot reference a project before the project is defined. When working with sub-projects, the project definition is stored by calling #define, and evaluated before a call to the parent project’s #define method returns.

However, if you call #project with the name of another sub-project, its definition is evaluated immediately. So the returned project definition is always complete, and you can access its definition (e.g. to find files relative to the base directory, or packages created by that project).

For example:

define 'myapp' do
  self.version = '1.1'

  define 'webapp' do
    # webapp is defined first, but beans is evaluated first
    compile.with project('beans')
    package :war
  end

  define 'beans' do
    package :jar
  end
end

puts project('myapp:beans').version

# File 'lib/buildr/core/project.rb', line 944

def project(*args)
  Project.project *args
end

#projects(*args) ⇒ Object

:call-seq:

projects(*names) => projects

With no arguments, returns a list of all projects defined so far. When called on a project, returns all its sub-projects (direct descendants).

With arguments, returns a list of named projects, fails on any name that does not exist. As with #project, you can use relative names when calling this method on a project.

Like #project, this method evaluates the definition of each project before returning it. Be advised of circular dependencies.

For example:

files = projects.map { |prj| FileList[prj.path_to('src/**/*.java') }.flatten
puts "There are #{files.size} source files in #{projects.size} projects"

puts projects('myapp:beans', 'myapp:webapp').map(&:name)

Same as:

puts project('myapp').projects.map(&:name)

#read(name) ⇒ Object

:call-seq:

read(name) => string
read(name) { |string| ... } => result

Reads and returns the contents of a file. The second form yields to the block and returns the result of the block.

struct(hash) => Struct

Convenience method for creating an anonymous Struct.

For example:

COMMONS             = struct(
  :collections      =>'commons-collections:commons-collections:jar:3.1',
  :lang             =>'commons-lang:commons-lang:jar:2.1',

end

#unzip(args) ⇒ Object

:call-seq:

unzip(to_dir=>zip_file) => Zip

Creates a task that will unzip a file into the target directory. The task name is the target directory, the prerequisite is the file to unzip.

This method creates a file task to expand the zip file. It returns an Unzip object that specifies how the file will be extracted. You can include or exclude specific files from within the zip, and map to different paths.

The Unzip object’s to_s method return the path to the target directory, so you can use it as a prerequisite. By keeping the Unzip object separate from the file task, you overlay additional work on top of the file task.

For example:

unzip('all'=>'test.zip')
unzip('src'=>'test.zip').include('README', 'LICENSE') 
unzip('libs'=>'test.zip').from_path('libs')

    task.enhance { setup.extract }
  end
end

#upload(*args, &block) ⇒ Object

:call-seq:

upload(artifacts)

Uploads the specified artifacts to the release server as part of the upload task.

You can use this to upload various files to the release server, for example:

upload artifact('group:id:jar:1.0').from('some_jar.jar')
$ buildr upload

Raises:

    end
  end
end

#write(name, content = nil) ⇒ Object

:call-seq:

write(name, content)
write(name) { ... }

Write the contents into a file. The second form calls the block and writes the result.

For example:

write 'TIMESTAMP', Time.now
write('TIMESTAMP') { Time.now }

Yields to the block before writing the file, so you can chain read and write together. For example:

write('README') { read('README').sub("${build}", Time.now) }

end

#zip(file) ⇒ Object

:call-seq:

zip(file) => ZipTask

The ZipTask creates a new Zip file. You can include any number of files and and directories, use exclusion patterns, and include files into specific directories.

For example:

zip('test.zip').tap do |task|
  task.include 'srcs'
  task.include 'README', 'LICENSE'
end
