Run ant in verbose mode : ant -v and looks for clues. Robert Munteanu Robert Munteanu This helped me a lot. I first tried building a project into a lib with jdk 1. I later discovered I needed to build it on 1. Using ant -v I discovered that ant was correctly using jdk1.

So all I did was delete the temporary folder, and it recreated them, this time with jdk 1. Might help someone — Mauro Banze. You could achieve that with following steps, if you are using Eclipse IDE: Right click on the task in your ant build file build. Add followings to "Arguments": -Dant.

Last but not least Apache IvyDE offer editors of ivy. The API of IvyDE has been stabilized so that third party plugins can rely on it, while still not complete, and still not advertised as stable in Ivy, support of OSGi has been added, javadoc and source attachement can be edited now one by one, improved stability of the resolve process, improved logging for easier debugging. This release is expected to work with every version of Ivy 2.

The OSGi features require Ivy 2. Home Projects. Ant 1. Key features of the 2. Oh— start —yes, we could provide a target for that. We should package our application. Now it's only one class—but if you want to provide a download, no one would download several hundreds files A startable jar file would be nice And it's a good practise to have a clean target, which deletes all the generated stuff.

Many failures could be solved just by a "clean build". By default Ant uses build. While having a look at the buildfile, we will see some similar steps between Ant and the Java-only commands:. Now that we have a working buildfile, we could do some enhancements: many times you are referencing the same directories, main-class and jar-name are hardcoded, and while invoking you have to remember the right order of build steps. Somebody told us not to use System -statements.

We use Log4J for that, because. We store our external libraries in a new directory lib. Log4J can be downloaded [1] from Logging's Homepage. Create the lib directory and extract the log4j After that we have to modify our Java source file to use that library and our buildfile so that this library could be accessed during compilation and run.

Working with Log4J is documented inside its manual. Already on GitHub? Sign in to your account. Overview We have a dependency on Ant environment variable "ant. If it's Java 8, we copy tools. This however doesn't work very well, since Ant is returning 1.
