Eclipse Mars：ANT任务引用缺少的SWT库

Question

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) ?

Answer 1

这对我有用：

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

Answer 2

Move the eclipse program directory to another folder wihtout spaces

• for example simply to c:\\eclipse

Answer 3

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.

Answer 4

一个可能的解决方案是创建文件夹“C：\\ Program％20Files \\ eclipse_lunar \\ plugins”并从“C：\\ Program Files \\ eclipse_lunar \\ plugins”中放置实际* .jar的副本
