Building With Ant
Echo uses the Apache Ant Build Tool for all build tasks, e.g., for building test application WAR files, running unit tests, or building final Echo releases that are uploaded to nextapp.com. If your system does not already have Ant installed, follow the directions on http://ant.apache.org to obtain and install it.
Servlet API Requirement
When building Echo, you will need to inform Ant of the location of a JEE servlet.jar file containing the Java Servlet API. This can be done by setting the SERVLET_LIB_JAR environment variable to the complete path of this jar, e.g.: /home/me/jetty/lib/servlet-api-2.5-6.1.5.jar or by specifying the location each time ant is called using the servlet.lib.jar variable, e.g.:
ant release -Dservlet.lib.jar=/home/me/jetty/lib/servlet-api-2.5-6.1.5.jar
Build Targets
The following build targets are supported by the Echo3 Ant build file:
release |
Builds a complete Echo release with source code, example applications, JARs, and documentation. This target takes a long time to build. |
dist.testapp |
Builds the server-side Java interactive test application. |
clean |
Cleans (deletes) all previous build output. |
