Earlier I was using some other build tool to build my project. Here if a target is built and if the same target is used to build some other target, it compares the timestamp and will not build the dependent targets again.
Ant doesnt compare the timestamps on targets, but it looks at the timestamp of artifacts consumed and created by tasks. e.g <javac> does work only if there is java source to compile, but the <javac> task is called on every build.
As I started working on ANT, I found it very useful and intersting.
But in ANT, while building each target, it will try to build all the dependent targets that many times as it occurs in different targets.
As a result it is increasing project\'s build time.Is there any task to ensure that the dependent targets once built will not be built again ????
Every target in a build file should run once. if the same targets run again and again in a single build, your are using <ant> when you dont need to. Every task in a target should do its own dependency rules, though some <javadoc> dont. You can use <uptodate> to determine if targets need skipping
