Ant build script

Download from Subversion the directory tree ‘pi’ which contains several Java source files using the command:

svn checkout http://svn4.cvsdude.com/sjsu_cs/cs160mak_alpha/pi

(If you are prompted for a user name and password, use ‘mjayne’ for both.)

You should then have:

• pi/
• src/
• numbercruncher/
• mathutils/
• BigFunctions.java
• piutils/
• PiFormula.java
• program13_3/
• PiBorwein.java
• PiBorweinAlgorithm.java
• PiBorweinConstants.java
• PiBorweinParent.java

Assignment

Create an Ant script build.xml in directory pi/ containing tasks that will:

• Create the archive file utils.jar in a new subdirectory pi/lib/ from BigFunctions.java and PiFormula.java.
• Compile the PiBorwein*.java files and put the .class files (with the appropriate package subdirectory hierarchy) into a new subdirectory pi/classes/. Put the archive file utils.jar on the classpath of the compilation so that BigFunctions.java and PiFormula.java are not recompiled.
• Run the program numbercruncher.program13_3.PiBorwein. Besides the classes directory, it will also need to have utils.jar on its classpath. The program takes one argument: the number of digits of pi to compute and print, e.g., 1000. This value should be defined in a separate build.properties file.
• Delete all generated files in preparation for a clean build.

You can download Ant from http://ant.apache.org/bindownload.cgi.
