ArcGIS Engine Developer Guide

BUILDING A COMMAND-LINE JAVA APPLICATION
• validate-engine—ensures that the ArcGIS Engine developer environment is
properly set.
• compile—compiles the scenario.
• execute—runs the scenario in a separate JVM instance.
• all—the default target, which builds the entire scenario.
• clean—cleans all build products.
• run-scenario—builds and runs the scenario application.
To get an idea of the structure of Ant targets, look at a sample compile target
line by line.
The entire build script is not discussed in detail
here; to learn more about building Ant scripts
see the Ant documentation available from the
Apache Ant Web site, http://ant.apache.org/.
As shown in the first line, this target has a name to reference and depends on
another target. To ensure a successful build, the ‘depends’ attribute is used to
confirm that the environment is set correctly.
In the last section of this sample target, one of ANT’s core tasks, “javac”, is
created to compile the files in the source directory and place them in the class
directory. The javac task supports a class path task to ensure the class path settings.
The complete sample target, including closure of the XML tags, is as shown
below:
Now that you have a basic understanding of targets and their usage in Ant,
proceed with creating the build.xml file for this scenario.
1. Create an XML file named build.xml and add the following:
&properties;
