Antwort: Re: [platform-ant-dev] Eclipse 2.1, Ant 1.5.2, log method -> NullPointerException



I've copied my custom jar to the directory org.apache.ant_1.5.2 and added
the corresponding entry in plugin.xml. That's all.
My task works fine outside of Eclipse.

Here is the stacktrace:
[greebo] Exception occured: java.lang.NullPointerException

Oliver,

I am guessing a little here as you neglected to provide the stack trace but
are you including your custom tasks within the plug-in JAR as well as in
your task JARs?

Please see
https://bugs.eclipse.org/bugs/show_bug.cgi?id=34466
or the Eclipse readme (known issues).

Hi everybody

I've downloaded Eclipse 2.1 where Ant 1.5.2 is integrated. If I want
register custom Ant task, I deployed my jars to the ant plugin and changed
the file plugin.xml. Unfortunately, I get a NullPointerException back. I've
found the reason in the call log() inside the task. The call log() does
work outside of Eclipse. Did anybody have the same problem?

Oliver
