Methods

MethodDescription
exclude(excludeSpec)

Adds an exclude spec. This method may be called multiple times to append new specs.The given closure is passed a FileTreeElement as its parameter. The closure should return true or false. Example:

exclude(excludes)

Adds an ANT style exclude pattern. This method may be called multiple times to append new patterns and multiple patterns may be specified in a single call. If excludes are not provided, then no files will be excluded. If excludes are provided, then files must not match any exclude pattern to be processed.

exclude(excludes)

Adds an ANT style exclude pattern. This method may be called multiple times to append new patterns and multiple patterns may be specified in a single call. If excludes are not provided, then no files will be excluded. If excludes are provided, then files must not match any exclude pattern to be processed.

exclude(excludeSpec)

Adds an exclude spec. This method may be called multiple times to append new specs. If excludes are not provided, then no files will be excluded. If excludes are provided, then files must not match any exclude pattern to be processed.

include(includeSpec)

Adds an include spec. This method may be called multiple times to append new specs. The given closure is passed a FileTreeElement as its parameter. If includes are not provided, then all files in this container will be included. If includes are provided, then a file must match at least one of the include patterns or specs to be included.

include(includes)

Adds an ANT style include pattern. This method may be called multiple times to append new patterns and multiple patterns may be specified in a single call. If includes are not provided, then all files in this container will be included. If includes are provided, then a file must match at least one of the include patterns to be processed.

include(includes)

Adds an ANT style include pattern. This method may be called multiple times to append new patterns and multiple patterns may be specified in a single call. If includes are not provided, then all files in this container will be included. If includes are provided, then a file must match at least one of the include patterns to be processed.

include(includeSpec)

Adds an include spec. This method may be called multiple times to append new specs. If includes are not provided, then all files in this container will be included. If includes are provided, then a file must match at least one of the include patterns or specs to be included.

source(sources)

Adds some source to this task. The given source objects will be evaluated as per Project.files(java.lang.Object[]).

Method details

SourceTask exclude(Closure excludeSpec)

Adds an exclude spec. This method may be called multiple times to append new specs.The given closure is passed a FileTreeElement as its parameter. The closure should return true or false. Example:

copySpec {

  into 'destination'
  //an example of excluding files from certain configuration:
  exclude { it.file in configurations.someConf.files }
}

If excludes are not provided, then no files will be excluded. If excludes are provided, then files must not match any exclude pattern to be processed.
