You can add a file to override the default-B-unit-engine config if needed, such as

<config file="engine-configuration.xml" />

Nested element

<engineProperties>

accepts a file relative or absolute path to a properties file with engine

config path=value

pairs in the format required by java.util.Properties. The file attribute is optional and instead nested

<engineProperty name="…" value="…"/>

elements can be used to set engine properties. If both the file attribute and the engineProperty elements are used, the elements will override the values in the properties file if the same config path is specified twice.

Examples of multiple engine properties:

<engineProperty name="Logging" value="urn:ae:execution" />
<engineProperty name="CustomFunctions/MyCustomFunction" value="com.test.my.custom.Function" />
