Subject: RE: [Eap-list] ant build
failed
This is the
problem (similar to what) I and some other people were
having.
I _think_ I know
where the problem comes from (I faced it in slightly different
case):
new Xerces (2.0)
is trying to be smart about classloaders (prolly they are right here) and when
attempting to load parser impl. (and other stuff) it obtains classloader using
Thread.getContextClassloader() HOWEVER the problem is that Ant, when calling
tasks does NOT set context classpath (and sounds like it is not going to in
the near future). The result is that the classloader Xerces gets a hold on is
a wrong one (I think it is IDEA's CL in our particular case) and that finally
screws things up.
The workaround
(quite ugly) I found is to replace xerces.jar in idea/lib with an older
version of xerces (1.4.x). It makes the build work, but breaks XML
validation.
I also tried
using
<taskdef reverseloader="true"> attribute (see link below), I am
not sure what exactly does it do. For me it did not work - caused
Linkage error violating loader constraints.
See this link
for discussion of this problem:
Anton: I believe
you were on this problem. Hope this information may help. Would running Ant in
a separate process help here?

Hi,
I am using the
Ariadna build 614. My ant scripts never work when I have a doctype entry
defined with a link to a .dtd.
The error I get
is:
build.xml
null
Build completed with 1 error. Time: 1 s
Or in full text
mode:

Build completed with 1 error. Time: 1 s
My ant scripts run perfectly outside IDEA, but never from within IDEA. If a comment the doctype tag, the script works fine from IDEA.
Another
thing I noticed are the error messages in the bottom status
bar
<!DOCTYPE project SYSTEM "C:/ant141.dtd"> no
error in status bar, but script doesn't work
either
Anyone noticed the
same
problems?
Regards,
Willem
