RE: [pde-dev] Resolving fullpaths from .classfile
|
Hi
Even I tried the same, but jere is how the eclipse is doing (this i tried
with debug on eclipse source once , when i was given the task of computing
classpath for a given project) reads the .classpath and prepares
IClasspathEntry out of it and finds what kind of entry it is, is it a lib
or source folder or some other refrenced project(s) , ....
it is ding what we want , but what a pity thing is it is in the
internal package. as you know so we are not suppose to use the classes which
starts with internal keyword since they are not supported and can be changed
in future release, that logic was nothing but a way i told u in prev mail
using a utility class to find out all the list of class files in a folder,
(but eclipse does using IFolder concept not using jdk)
so for my task i followd the logic as I said in the previous mail.
upto my knowledge this is and till now its is the way. i will search for
some other stuffs, in the mean time better implement that logic in a
abstract class/interface and carry on. if i found that i will send it to u
and then replace the code. lets see ....
if you still want that code execute a this method in debug mode,
project.build(IProgressMonitor), this will take you finally to the code
which is in internal package. it will read classpath entry and prepare
absolute path etc... but for me complete debug took nearly 45 mins to get in
to the flow and understand what it does ...since all of them are eclipse
specific classes. instead of doing that simply with in 50-100 lines you can
do it using JDK utilities.
if you find any alternative do pl. mail me.
cheers,
Pradheep.

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..

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
