Hello,
I am posting to this group since I am not getting any guidance apart
from
"look at ant source code".
I am trying to use ant programmatically using the Ant API.
When executing the code
it throws NullPointerException for the line
tinstaller.setClasspath(class_path);
in the code.
It is for the class "org.apache.tools.ant.taskdefs.Taskdef;"
But for the other taskdefs e.g. Javac its O.K.
Is there any problem to load classpath in Taskdef object?
If not then where's the wrong with the code?
The Exception
Subir,
The reason we are all saying "look at the code" is because nobody else
has encountered this situation. If we were trying to do what you are
trying to do, then I'd probably set a breakpoint in my code before I
call this stuff, and find out why an NPE is being thrown. On the
particular line, something is being derefed that is null. Find out what
it is, find out why it isnt being set, make sure that it gets set and
continue.
Nobody can debug your code remotely, and if you are using ant
programmatically, you have to expect less support from ant-from-XML, as
that is how it is normally used.
