Options Tab (Ant Transformations)
When you create a new transformation scenario or edit an existing one, a configuration dialog box allows you to customize the transformation with various options in several tabs.
The Options tab allows you to specify the following options:
- Working directory
- The path of the current directory of the Ant external process. You can
specify the path by using the text field, the
Insert Editor
Variables button, or the 
Browse button. - Build file
- The Ant script file that is the input of the Ant external process. You can
specify the path by using the text field, the Insert Editor
Variables button, or the Browse button.
- Build target
- Optionally, you can specify a build target for the Ant script file. If no target is specified, the Ant target that is specified as the default in the Ant script file is used.
- Additional arguments
- You can specify additional command line arguments to be passed to the transformation (such as -verbose).
- Ant Home
- You can choose between the default or custom Ant installation to run the transformation.
- Java Home
- You can choose between the default or custom Java installation to run the transformation. The default path is the Java installation that is used by Oxygen XML Developer plugin.
- JVM Arguments
- This parameter allows you to set specific parameters for the Java Virtual Machine used by Ant. For example, if it is set to -Xmx384m, the transformation process is allowed to use 384 megabytes of memory. When performing a large transformation, you may want to increase the memory allocated to the Java Virtual Machine. This will help avoid Out of Memory error messages (OutOfMemoryError).
- Libraries
- By default, Oxygen XML Developer plugin adds libraries (as high priority) that are not transformation-dependent and also patches for certain DITA Open Toolkit bugs. You can use this button to specify additional libraries (jar files or additional class paths) to be used by the Ant transformer.
