Hi
I am developing a plugin where I am managing
the java build classpath for a project. In this
way I can change the jar files the project is using.
In Eclipse when you select a jar file and open the
associated properties window you can manually attach
the java source (for debuging purposes). In my case
this is also a jar file.
My question is: how can I do this 'java source attachment'
programmically in my plugin?

What is missing?

The first IPath should be the path to the source JAR file, the second IPath
should be the root path in the source JAR file where the source starts. I.e.
if your source JAR file's structure is:
src/com/my/package/X,java
src/com/my/package/other/Y.java
then the root path is 'src'.
Note this root path can be null if you want is to be autodetected (this
costs a little bit more).
So you should write:
pfr.attachSource(jarSrcFile.getFullPath(), null, null);

Hi
Yes, I mixed up things with the attachSource method. When I have the jar
file and the source jar file in the project workspace then I can make it
work with the following code:
public void doAttachSource(IFile jarFile,IFile jarSrcFile){
try {
IPackageFragmentRoot pfr =
JavaCore.createJarPackageFragmentRootFrom(jarFile);
pfr.attachSource(jarSrcFile.getLocation(),new Path(""),null);
} catch (JavaModelException e1) {
...
} catch (Exception e2){
...
}
}
In my version of Eclipse (2.0.3 / wsad 5.0.1) I get a null pointer
exception
if I use null as the rootPath. However it works when creating a Path with
an empty string.
However, I have another problem. I also need to attach the source jar to
a jar file both placed outside the workspace. The jar file is included in
the projects java build path with a classpath variable (say X) and an
extension (say Y/file.jar).
Using either the full path to the jar file or the string (X/Y/file.jar)
I cannot successfully create the needed IFile object required to create the
IPackageFragmentRoot. How do I do this? I am a little bit stuck with this.
A final question. You can manually attach a source jar file to a jar file
through the properties window. If I do this by code instead, is there a
way to make this visible in the properties window? There seems to be
different
properties window for this when the jar file is placed local in the
project workspace and when it is referenced through a classpath variable.

Assume you have a classpath variable defined like this
MY_CLASSPATH_VARIABLE that is mapped to the path 'C:/a/b/c'
and that the jar files are placed relative to this at
'/some_folder/classFile.jar'
and '/some_folder/sourceFile.jar'
Sure you can define the IPath objects like this
IPath jarPath = JavaCore.getResolvedVariablePath(new
Path("MY_CLASSPATH_VARIABLE"));
jarPath = jarVariablePath.append("/some_folder/classFile.jar");
If you print this out with
System.out.println(jarPath.toString());
you get the string
'C:/a/b/c/some_folder/classFile.jar'
In a similar way you can define the source jar IPath object
IPath srcPath = JavaCore.getResolvedVariablePath(new
Path("MY_CLASSPATH_VARIABLE"));
srcVariablePath = srcVariablePath.append("/some_folder/sourceFile.jar");
In order to attach source to the jar file I have to create the
IPackageFragmentRoot
object. It takes an IFile object associated the jar file as argument.
My problem is to create the IPackageFragmentRoot object because when I
create
the IFile object based on the IPath object 'jarPath' it do not translate
into
a usefull IFile object.
If I do like this
IFile jarIFile = project.getFile(jarPath);
and make a printout:
System.out.println(jarIFile.getLocation().toString());
I get something like this
'C:/my_runtime_workspace_path/my_project/a/b/c/some_folder/c lassFile.jar'
that ofcourse do not exist, consequently I cannot create the
IPackageFragmentRoot object
on which I have to make the attachSource operation.
Any ideas?

Thanks, your comments helped a lot.
The last question I have is this:
If you select at jar file and through the view context menu open the
associated Properties window, you can select the "Java Source Attachment"
property. I am not sure if this is an Eclipse or WSAD feature though.
Nevertheless, here you manually can specify a source jar file to be
attached to. At a later time you can open the Properties window associated
the jar file resource and see what source jar file that is the current
attached source. I guess this value is stored as a persistent property.
However, if I attach the source by means of my own plugin as we have
discussed,
then this is not reflected by the Properties window. I suppose this is
because
the relevant persistent property has not been changed accordingly. Is
there a way for me to set this persistent property? I guess I just need to
get the qualified name for this property, but I don't know where to look.

It sounds like a bug. Please enter a bug against JDT/Core.
