It helps, thx.
Do you think this will also handle both the cases where classpath is defined
in <taskdef> and
mytask.jar is in ANTHOME\lib or elsewhere?
if (this.getClass().getClassLoader() instanceof AntClassLoader){
AntClassLoader antClassLoader =
(AntClassLoader)this.getClass().getClassLoader();
taskClasspath = System.getProperty("java.class.path") + ";" +
antClassLoader.getClasspath();
}
else {
taskClasspath = System.getProperty("java.class.path");
}
Path classpath = new Path(getProject());
classpath.setPath(taskClasspath);
javaTask.setClasspath(taskClasspath);
Originally when I started it, I didn't want to wrap it with <java>. My jar
file has some external dependencies on JAXB, Spring etc. I can only succeed
when I copy it to Ant/lib. Injecting my own classpath into Ant class loader
is too challenging for me. I believe it is quite common situation for task
writer. I am interested to learn how to do it too if possible.
thanks again.
