| Calling Ant from a Java main? | Calling Ant from a Java main? 2004-02-13 - By DDU DUQUENNOY Didier
Hi,
I'm (still) trying to automate the run of the junit tests of all my modules,
running Ant 1.6.0 on a Windows 2000 machine.
Each module has a build.xml script with a 'test' task defined. The test task
first compile the classes and then run a junit task which outputs a XML file.
I want to be able to invoke all these tasks and then build a report using
<junitreport>.
The problem I'm facing are:
- if a module doesn't compile, I want the next module to be tested.
- if a module doesn't compile I'd like to be able to see it in the final report
I first thought of a main script like this :
<target name="runtests" depends="clean">
<ant dir="${root}/module1" target="test"/>
<ant dir="${root}/module2" target="test"/>
[...]
</target>
but it isn't OK because the run will stop if a module doesn't compile.
So I though of writing a main java class to call my ant scripts. I should then
be able to detect the failure of a test a do what I want then.
Here are the techniques I tried:
- use java.lang.Runtime.exec(<cmd line>) : I go asynchronous and I can't check
the state of the run
- use org.apache.tools.ant.launch.Launcher : the first script runs, but it
seems that there is a System.exit() after :-(
- use or a ProjectHelper to build the project :
ProjectHelper.getProjectHelper();
Project project = new Project();
helper.parse(project, xmlFile);
Target target = (Target)targetTable.get("test");
target.execute();
but I get an error "Could not create task or type of type: junit". But junit
.jar and all the contents of Ant1.6/lib is in my classpath
- use of org.apache.tools.ant.taskdefs.Ant to simulate a <ant dir="${root}
/module1" target="test"/> :
Ant antTask = new Ant();
antTask.setProject(new Project());
antTask.setAntfile(xmlFile);
antTask.setTarget("test");
antTask.execute();
but I get an error "Could not create task or type of type: property". (???)
Well, how can I do the trick?
