Base class for code quality tasks.

### Properties

Property | Description
`excludes` | The set of exclude patterns.
`ignoreFailures` | Incubating Specifies whether the build should break when the verifications performed by this task fail.
`includes` | The set of include patterns.
`javaLauncher` | Incubating Java launcher used to start the worker process
`maxHeapSize` | Incubating The maximum heap size for the worker process. If unspecified, a maximum heap size will be provided by Gradle. Supports units like the command-line option `-Xmx` such as `"1g"`.
`minHeapSize` | Incubating The minimum heap size for the worker process. When unspecified, no minimum heap size is set. Supports units like the command-line option `-Xms` such as `"1g"`.
`source` | The source for this task, after the include and exclude patterns have been applied. Ignores source files which do not exist.

### Methods

Method | Description
`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[])`.

### Property details

#### ``Set`<`String`>` `excludes`

The set of exclude patterns.

#### `boolean` `ignoreFailures`

Note: This property is incubating and may change in a future version of Gradle.

Specifies whether the build should break when the verifications performed by this task fail.

Default value:
  false

#### ``Set`<`String`>` `includes`

The set of include patterns.

#### ``Property`<`JavaLauncher`>` `javaLauncher`

Note: This property is incubating and may change in a future version of Gradle.

Java launcher used to start the worker process

#### ``Property`<`String`>` `maxHeapSize`

Note: This property is incubating and may change in a future version of Gradle.

The maximum heap size for the worker process. If unspecified, a maximum heap size will be provided by Gradle. Supports units like the command-line option `-Xmx` such as `"1g"`.

#### ``Property`<`String`>` `minHeapSize`

Note: This property is incubating and may change in a future version of Gradle.

#### `FileTree` `source`

The source for this task, after the include and exclude patterns have been applied. Ignores source files which do not exist.

The `PathSensitivity` for the sources is configured to be `PathSensitivity.ABSOLUTE`. If your sources are less strict, please change it accordingly by overriding this method in your subclass.

### 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 {
      from 'source'
      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.

#### `SourceTask` `exclude`(``Iterable`<`String`>` 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.

#### `SourceTask` `exclude`(``String`...` 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.

#### `SourceTask` `exclude`(``Spec`<`FileTreeElement`>` 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.

#### `SourceTask` `include`(`Closure` 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.

#### `SourceTask` `include`(``Iterable`<`String`>` 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.

#### `SourceTask` `include`(``String`...` 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.

#### `SourceTask` `include`(``Spec`<`FileTreeElement`>` includeSpec)
