B.5 Utilizing incremental compilation using an Ant task in Java

Creator QR-Code in Java B.5 Utilizing incremental compilation using an Ant task

The AspectJ Ant task can be set to compile the source files incrementally, based on user input. Just like the incremental option to ajc (discussed in section A.8),

the incremental mode of the AspectJ Ant task tracks the files specified using the sourceroots element (or the sourceRoots or sourceRootsList attribute). The following Ant task compiles the source files under the shopping and tracing directories in incremental mode:

<target name="inc-compile"> <mkdir dir="dest"/> <iajc destdir="dest" incremental="true"> <sourceroots> <pathelement location="shopping"/> <pathelement location="tracing"/> </sourceroots> </iajc> </target>

Invoking the target results in a full initial compilation followed by a request for user input. The user must then press Enter (to recompile), r (to rebuild), or q (to quit the process):

> ant inc-compile Buildfile: build.xml inc-compile: [mkdir] Created dir: F:\aspectj-book\appendixB\sectionB.5\dest [iajc] press enter to recompile, r to rebuild, q to quit: [iajc] r [iajc] [iajc] q BUILD SUCCESSFUL Total time: 22 seconds press enter to recompile, r to rebuild, q to quit: press enter to recompile, r to rebuild, q to quit: press enter to recompile, r to rebuild, q to quit:

For large projects, you will notice a significantly reduced recompilation time compared to the initial compilation.

Here we ve compiled a listing of books, papers, and online resources related to AOP and AspectJ. In addition, we ve listed sites where you can find the technologies used in our examples. We ve also included URLs to useful mailing lists to which you can subscribe.
