Relative Path for adding jar files? [message #266970]

Hi,
I'm adding some third party jar files in my project and want to distribute
my project along with the jar files to some people. But the problem is,
when I add the jar files in my project, the classpath copies the absolute
path of the files, which will of course not work on some other machine if
he doesn't copy the files at the exact same location.

How to make eclipse to add a path relative to my project?

Thanks !

I put jar files directly in the root of my project. This makes the
..classpath file system independent and suitable for version control. It
is a bit more troublesome to have source and javadoc locations relative
as well. Along with that you can add *.jar to svn:ignore (or whatever
system you’re using).

Where exactly do you put these jars? If you put them somewhere inside
your project, e.g. in a directory named 'libs', and add them to the
build-path, the classpath entry should be relative to your project root.
To add a jar, simply rightclick it and select 'Add to build-path'.

Hi,
I'm doing exactly the same. I have created a folder called 'lib' in my
root project folder, which has others like .settings, bin, src folders at
the same level.

And I added these .jar files by clicking 'configure build path' and doing
an 'add external jars'

It did not take relative path.

Got it. I had to click 'Add jars' after refreshing the project. Earlier I
was not seeing anything in the add jar button because I had not refreshed
the project to show my lib folder.

Thanks for your help.

If you did not want to include the JARs in your project, you could use a
User Library or Classpath Variable to allow each user to specify their
location on his own machine. Here is the relevant Help page:
http://help.eclipse.org/ganymede/topic/org.eclipse.jdt.doc.u ser/reference/preferences/java/ref-preferences-build-path.ht m

Hope this helps,
Eric
