You can set options to determine how artifacts that a transformation
generates are merged or overwritten in the target project. For example,
you can perform a visual merge in which you view and confirm changes
to the target project, you can silently merge nonconflicting changes,
or you can automatically overwrite the target source with all changes
that the transformation generates.
Procedure
- Open an existing transformation configuration file, or
create a new transformation configuration.
- On the Main page,
select from the following merge options:
| Option |
Description |
|---|
| Visual merge |
This option opens the Merge the Transformation Output window
and starts a merge session so that you can review and resolve differences
between generated target content and existing target content. |
| Silent merge |
This option prevents a transformation output merge when changes
occur either in the transformation source or in the transformation
target. |
| Do not merge: Overwrite files without a warning |
This option overwrites existing files with generated files
automatically. |
| Do not merge: Warn before overwriting any files |
This option opens the Replace Resources window, which prompts
you for confirmation before overwriting existing files with generated
files, and adds new artifacts automatically. If you do not want to
overwrite an existing resource, you can clear its selection in the
window. |
| Automatically add new elements to the target model |
When you use the visual merge capability, this option adds
new artifacts to the target project source without prompting you for
confirmation. To enable this option, select Visual merge. |
| Save changes before validating files |
To validate a transformation output artifact, you must save
a modified artifact. When you use the visual merge capability, this
option automatically saves resources that you select for validation.
To enable this option, select Visual merge. |
| Automatically validate saved changes |
When you use the visual merge capability, this option automatically
validates a resource after you save it. To enable this option, select Visual
merge. |
- Click .
Results
The options are applied the next time that
you run the transformation.
