Hi,
I would like to know how to start a batch file in a new dos window
without blocking the java process and so naturally I
tried the following that does work:
<project name="project" default="target" basedir=".">
<target name="target">
<exec executable="cmd" spawn="true" dir="${basedir}">
<arg value="/c"/>
<arg value="start"/>
<arg value="test.bat"/>
</exec>
</target>
</project>
However I need to be able to do this from java and so I used the
following snippet of code that I thought would
represent the same functionality as the ant script:
public static void main(String[] args) throws IOException {
// top level project
Project project = new Project();
project.setName("project");
project.init();
// project has a target child
Target target = new Target();
target.setName("target");
project.addTarget(target);
// target has an exec child
ExecTask execTask = new ExecTask();
execTask.setProject(project);
target.addTask(execTask);
execTask.setExecutable("cmd.exe");
execTask.setSpawn(true);
execTask.setDir(new File("."));
addArg(execTask, "/c");
addArg(execTask, "start");
addArg(execTask, "test.bat");
target.execute();
}
However it doesn't matter whether or not I set true of false for the
spawn property the java process blocks
every time until I close the dos window by hand. Is there something
else I need to do to more closely
replicate the ant script?
Cheers
- Ashley
