Ant 1.10.3 released with JUnit 5 support

We just released 1.9.11 and 1.10.3 versions of Ant today. The downloads are available on the Ant project's download page. Both these releases are mainly bug fix releases, especially the 1.9.11 version. The 1.10.3 release is an important one for a couple of reasons. The previous 1.10.2 release, unintentionally introduced a bunch of changes which caused regressions in various places in Ant tasks. These have now been reverted or fixed in this new 1.10.3 version.

In addition to these fixes, this 1.10.3 version of Ant introduces a new junitlauncher task. A while back, the JUnit team has released JUnit 5.x version. This version is a major change from previous JUnit 3.x & 4.x versions, both in terms of how tests are written and how they are executed. JUnit 5 introduces a separation between test launching and test identification and execution. What that means is, for build tools like Ant, there's now a clear API exposed by JUnit 5 which is solely meant to deal with how tests are launched. Imagine something along the lines of "launch test execution for classes within this directory". Although Ant's junit task already supported such construct, the way we used to launch those tests was very specific to Ant's own implementation and was getting more and more complex. With the introduction of this new API within the JUnit 5 library, it's much more easier and consistent now to launch these tests.

JUnit 5, further introduces the concept of test engines. Test engines are responsible for "identifying" which classes are actually tests and what semantics to apply to those tests. JUnit 5 by default comes with a "vintage" engine which identifies and runs JUnit 4.x style tests and a "jupiter" engine which identifies and runs JUnit 5.x API based tests.

The "junitlauncher" task in Ant introduces a way to let the build specify which classes to choose for test launching. The goal of this task is to just launch the test execution and let the JUnit 5 framework identify and run the tests. The current implementation shipped in Ant 1.10.3, is the basic minimal for this task. We plan to add more features as we go along and as we get feedback on it. Especially, this new task doesn't currently support executing these tasks in a separate forked JVM, but we do plan to add that in a subsequent release.

The junit task which has been shipped in Ant since long time back, will continue to exist and can be used for executing JUnit 3.x or JUnit 4.x tests. However, for JUnit 5 support, the junitlauncher task is what will be supported in Ant.

More details about this new task can be found in the junitlauncher's task manual. Please give it a try and report any bugs or feedback to our user mailing list.

WildFly 12.0.0.Beta1 tagged and available

WildFly 12.0.0.Beta1 has been tagged and has been (I think) officially released. The announcement happened a few days back in the dev mailing list and unlike the previous releases, this time the release binaries seem to be only available in Maven repository and can be obtained from here - WildFly 12.0.0.Beta1 distribution (the .tar.gz and .zip are the relevant ones). The list of changes for this release can be found in the JIRA release notes.

As you'll notice in the release notes, there's some initial support for EE 8 specs, including Servlet 4.0 among others. Plus there's also numerous bug fixes in this release from the previous 11.0.0.Final version which was released some months back. As usual, please give this version a try and if there are any issues or feedback that you would like to report, please start a discussion in the WildFly user forum

If you haven't been following the WildFly dev mailing list, there's also a discussion which outlines the release plans for WildFly going forward. You can find that discussion here

Finally, there's been major changes to Java EE processes and committee and even the name, over the past year. If you haven't been following those changes, then you can read through Mark Little's recent blogs including the most recent ones which talk about the new brand name for Java EE  and setting up of the working group.

Apache Ant new versions (1.9.10 and 1.10.2) released

This past year has been pretty hectic, so I haven't had a chance to update this blog more often.

In my limited spare time last year, I started contributing to Apache Ant project. Although Ant probably isn't as widely used as some years back, it still is used in many projects, as the build tool. Some of the products I'm involved in, does use Ant and that motivated me to contribute to some bug fixes in Ant. After a period of time, last year, I was invited to be a committer and a few weeks back, to be part of the Ant project management committee (PMC), which I consider a honour.

Just today, we released a couple of new versions of Ant - 1.9.10 and 1.10.2. These are essentially bug fix releases but do contain some new enhancements. The complete release notes, for each of these releases, can be found  here and here.

The downloads are available from the project's download page and the full announcement, in the mailing list, can be read here

If you have any issues/suggestions/feedback about the project, feel free to report it in the user mailing list which is listed on this page.
