I just upgraded to Eclipse Mars and suddenly my ANT task working fine with Lunar complains:

The archive: C:/Program%20Files/eclipse_lunar/plugins/org.eclipse.swt.win32.win32.x86_64_3.104.0.v20150528-0211.jar which is referenced by the classpath, does not exist.

Which is weird, because

  • I'm sure none .classpath file does reference to this jar
  • the jar actually exists under that path

After some research it seems it is related to https://bugs.eclipse.org/bugs/show_bug.cgi?id=470390

Anyone has a solution to run my ANT (besides from using lunar again) ?

This worked for me: 

mklink /D D:\Program%20Files "D:\Program Files"

Move the eclipse program directory to another folder wihtout spaces

  • for example simply to c:\eclipse

Problem:

Error message:

The archive: C:/Program%20Files%20(x86)/Eclipse%20Mars/plugins/org.eclipse.swt.win32.win32.x86_64_3.104.0.v20150528-0211.jar which is referenced by the classpath, does not exist.

The problem was the Eclipse Mars is downloaded and extracted under a folder which space contained in its name. In the above error message the path contains folder names with spaces in between and displayed as %20.

Solution:

Inorder to solve this use anyone of the workaround mentioned below,

  • Remove any spaces in any of the directory where you have stored Eclipse.
    eg: Rename My Folder to MyFolder
  • Move you eclipse to the root of any drive(C: or D: or F: etc)
    eg: D:\eclipse-jee-mars-R-win32-x86_64

  • Create a symbolic link folder in windows using mklink command,

    mklink /d D:\My%20Folder "D:\My Folder"

You'll get the following message,

symbolic link created for D:\My%20Folder <<===>> D:\My Folder

Note: For creating symbolic link you need to run the above command in the elevated command prompt.

Now you can run the ant scripts without the above error. This is a bug reported to eclipse and will be patched in the future releases.

A possible solution is to create the folder "C:\Program%20Files\eclipse_lunar\plugins" and place a copy of the actual *.jar from "C:\Program Files\eclipse_lunar\plugins" there

  • I wouldn't recommend this, as it could potentially cause inexplicable behavior from other programs further down the line. A contrived example is to try to cd into that folder in a batch script. – Tyler Hoppe Mar 03 '16 at 23:50
