hi

first you have to take the actual classpaths:

IClasspathEntry[] oldEntries = javaProject.getRawClasspaths();

then create a new array of IClasspathEntry, but now with capacity for the
new classpath we want to add

IClasspathEntry[] newEntries = new IClasspathEntry[oldEntries.length+2];
System.arrayCopy (oldEntries,0,newEntries,0,oldEntries.length);
newEntries[oldEntries.length]=JavaRuntime.getDefaultJREConta inerEntry();

and then you have to add the path of the folder you want. To create a
IClasspathEntry out of a path you can use:

JavaCore.newSourceEntry
JavaCore.newLibraryEntry

depending on the the kind of classpath you want to create

then have to set the new claspaths:

javaProject.setRawClasspath (newEntries,null);

> JavaCore.newSourceEntry
> JavaCore.newLibraryEntry

I know this and I add easy base source, runtime library and jar libraries
and I want add folder btw:

/home/snpe/classes

When I create IClasspathEntry for this ?

I try
IClasspathEntry entry = JavaCore.newLibraryEntry(new
Path("/home/snpe/classes"),null,null);

but after javaProject.setRawClassPath my src lib,runtime lib and jar libs
are in classpath, but folder path not

Thanks

I play with classpath yet - Classpath engine in eclipse try find class in
workspace when path is folder - don't try /home/snpe/classes then
WORKSPACE_HOME/home/snpe/classes (probably need project home too)
It is a problem with test environment - test start in empty workspace and I
have export to jar libraries all dependencies plugins for test project

Is there solution ?

You can create a folder in your project linked to the folder you want to
add to the classpath. Then, instead of adding the original folder, add the
linked one.

I think that a bug related to this problem has been posted.

don't know if there's a better solution for this. At least i don't know
it. If you ever find another way, please send me an email telling me how.
