RE: [pde-dev] Resolving fullpaths from .classfile

[ravikanth.bhamidipati@xxxxxxx]

Hi 

Thanks for the responses,,,

Infact i cant share my source code,
but i am using IClasspathEntry and IClasspath classes already to differentitate
what type of classpath entry is that in .classpath...

Suppose if classpathentry kind is CPE_LIBRARY
i am doing it some way,, if it is CPE_SOURCE i am manipulating my path
some how,, 

But wha ti am hoping for is a general
strategy what ever may be the entry in .classpath file, read the library
or source and get its full path,, in other sense ,, 

Can I get the path platform takes for
building,,,, ?  What path eclipse sets for itself and compiler to
compile,, that path i want,,, 

can i get it,, 
so that one shot ,, every thing will
be done,, 

Thanks 
Regards






Hi boss,

  ok now look this method in a different angle.

  IProject myWebProject = myWorkspaceRoot.getProject("Myproject");

this will give instance of any project either closed or open / referenced
or 
not refernced that is in work space.  ok . what you've to do is give
any 
project name here, (itwill return null if the project doesnot exist in
work 
space)else give you a IProject instance of that project..... proceeed....

for example you want to refer a file in the project ABC which is not refered
by the current project,
at this time also you can use this method, to get instance of ABC, once
u 
get the IProject you can use this

       IFolder getFolder(String name) from IProject. where
name is again 
project name,

       which will give you where the project is mapped to
hard drive, then 
you can get absolute path of the project and blah blah....

      after getting absolute path write a small utility
using JDK to get 
llist of files present in the directory then include in them in classpath
if 
they are java and resource files and enjoy.

if this is also not working for you, there is a straightaway method to
retrieve all the classpath entries from a project can you try this. i will
look in to this tomorw, and get back to you bcas i m going home now,

        if you need this urgently pl. look into the
api of these classes 
i've specified below i am sure,  i've used it once(with out refferring
.classpath). can you please look into API of 
IClasspath/IClasspathEntry....>??? let me know if both are not working
....... from IClasspath entry you can get the absolute path also.

hope now yours seems ok now,  if not mail me, i will try my best.
Nothing is 
impossible...

regards,
Pradheep.

Yeah you are right till there..

myWorkspaceRoot =
ResourcesPlugin.getWorkspace().getRoot();

i was already using getReferencedProjects()  to get all the projects
being
referenced. ..But the problem lies here , it only gives me the project
referenced,,,i.e   if i specify my project "Project1" depends
on
"Project2" , but i didnt specify this instead i specified in
the java
buildpath , my project "Project1" is dependent on  some
class folder of
project2 i.e in my case "Project2/bin"  .

so no way i can get the project name from getReferencedProjects();
Another case is that if i keep my class files in some folder and then say
addclassfolder from java buildpath then it will ask me to enter a physical
name and asks me to map this name to the actual locaiton , at that time,,
it becomes even more difficult for me to find the actual full path..
  <classpathentry kind="lib" path="myclassses"/>
where myclasses is the name i have given to the platform and actually this
myclasses points to c:\myeclipseclasses\bin folder.

how can i resolve if the case is above

Thanks for continuous help
