How to import multiple projects into Eclipse using command line?

Is there anyway that I can use command line to import multiple projects into Eclipse workspace all at once? I noticed that someone suggests using command line as follows:

eclipse -nosplash -application org.eclipse.cdt.managedbuilder.core.headlessbuild -importAll {[uri:/]/path/to/project}

But I cannot figure out the {[uri:/]/path/to/project} part correctly. Any example? Also, is the above command line the only way I can achieve this? (it seems like to depend on CDT?) Is there any other way I can do this in command line?

Thank you!

did you tried copying the project folders to workspace directly and see if they are available as projects - Satya
Hey did you find any answers yet? This would be a very powerful feature. - Denis

The only documentation of headlessbuild I've found so far is the source. This reveals that the argument to -importAll should be the path to a directory containing all your projects. You can use -importAll repeatedly to import multiple trees of projects.

e.g. if you have the structure

tree/
  core/
    alpha/
      .project
    beta/
      .project
  edge/
    one/
      .project
    two/
      .project

Then this will build the four projects in a workspace tree/workspace:

cd tree
eclipse -nosplash -data workspace -application org.eclipse.cdt.managedbuilder.core.headlessbuild -importAll core -importAll edge -build

On Windows, use eclipsec.exe.

The Eclipse CDT provides tools to import projects via the command line. You can use the following command / options to do so.

eclipse -nosplash 
  -application org.eclipse.cdt.managedbuilder.core.headlessbuild 
  -import     {[uri:/]/path/to/project} 
  -importAll  {[uri:/]/path/to/projectTreeURI} Import all projects under URI
  -build      {project_name | all} 
  -cleanBuild {project_name | all}

Try using the absolute path for the url. e.g. /usr/fred/foo

A few things to note:

  1. You can specify the -import option multiple times
  2. Use Linux file path separators instead of the evil DOS separators (i.e. / instead of \).
  3. The uri should point to a directory and not a project name. So, if you have a project called foo in the directory path/to/FooBar, the option would be -import path/to/FooBar

Here is a real world example that I use.

eclipsec -noSplash -data "WORKSPACE2" -application org.eclipse.cdt.managedbuilder.core.headlessbuild  -no-indexer  -import 21-6912-xx-xpathparser -import 21-6912-xx-xpathparser/lib

output:

Create.
Opening 'libxpathparser'.
Create.
Opening '21-6912-xx-xpathparser'.
Saving workspace.
