## Introduction

Apache Ant provides several optional tasks for working with ClearCase. These tasks correspond to various ClearCase commands using the `cleartool` program. The current tasks available for Ant correspond to only a few of the significant ClearCase commands.

More tasks can be easily added by deriving from the ClearCase class and then adding functionality that is specific to that ClearCase command.

Important: these tasks all require `cleartool` on the command line. If a task fails with an `IOException`, especially `error=2` on Windows, this is your problem.

## CCCheckin

### Description

Task to perform a `cleartool checkin` command to ClearCase.

### Parameters

Attribute | Values | Required
--- | --- | ---
viewpath | Path to the ClearCase view file or directory that the command will operate on | No
comment | Specify a comment | No; only one of the two may be used
commentfile | Specify a file containing a comment
nowarn | Suppress warning messages | No
preservetime | Preserve the modification time | No
keepcopy | Keeps a copy of the file with a `.keep` extension | No
identical | Allows the file to be checked in even if it is identical to the original | No
failonerr | Throw an exception if the command fails | No; default is true

### Examples

Perform a ClearCase `checkin` on the file `c:/views/viewdir/afile`. Comment text from the file `acomment.txt` is added to ClearCase as a comment. All warning messages are suppressed. The file is checked in even if it is identical to the original.

    <cccheckin viewpath="c:/views/viewdir/afile"
               commentfile="acomment.txt"
               nowarn="true"
